As I stated before this video dropped, the QBombs are good budget SPL oriented prefab boxes. Can you do better with a custom built box? Of course but, but if you need something cheap and easy or catch these on sale, it's hard to imagine a better boom for your buck.
I love your honesty, and totally agree with everything you said in this video. In my experience the heavier and stronger your box is the better it'll perform and longer it'll last. I haven't heard much about d4s prefabs but I can't say I wouldn't enjoy seeing an honest un-biased review of it. Thanks for sharing and taking the time to enlighten us all. Take care and stay healthy
I have a dual 10 d4s prefab box. I had pair of american bass xr in it and they banged hard. I tried to put a pair of soundqubed and they sound trap but they require more space
For those whom not aware of the box tuning, one can not tune a box without a sub to tune it to. Not most are not aware that Qpower offers their own in house subs for which they tune these boxes from. Most subs will play well in these and other enclosures but the tuning will very due the specs of each sub being used. It's great to see these prefab tested and look forward to seeing more of them tested in the future
I was really impressed in in the qbomb myself I have had probably 6 different style ones. Great price and decent sound for dirt cheap prefab box. I do appreciate that you take the time to read all are comments and try things out that we like see.
Damn one day is tomorrow go buy the smallest van you can find Sound deadening that sucker put two 18's in the right kind of enclosure and Exo and Sandman will be worried 😟
I loved the look of mine for two kicker r 12's. Sounded horrible on lower end frequencies. So I added some poly batting sheets to inside walls with spray adhesive. Sounded awesome after that.
Thanks for being honest, that is appreciated. I also felt the same when my son first bought one of these boxes, but after listening to it I quickly changed my mind. Audio has come a long way in the last 20 years the names I once held in high prestige I have learned to question lately. These up and coming brands are beating the brakes off of them and doing it for a fraction of the cost. Skar Audio is one of the company’s I have found that is very impressive for the price.
Best box for the price, I have the same box with a 12" skar SDR-12 d2, @ 1ohm. I think the coating/logo/etching is cool, better than the boring rat fur carpet style, but no one looks in my trunk. Great Video
If you ever want to upgrade from the SDR, I would HIGHLY recommend looking at the DDX-12. SUPER SUPER Efficient sub! Get's REALLY loud on very little power, but they can handle 1500w~ RMS too.
I highly recommend buying a different box. When I connected my 12 sub it shook a lot like you said and after a month or 2 the bottom of the front side cracked all the way through. Sounded like complete garbage after that. It’s a good temporary box, but don’t get it if you plan on keeping it for more than a few months.
As a box builder, I have seen many prefabs...... some sound good but its the life of the box. most dont last very long. Ive been building for 8 years and never

@@DIYAudioGuy no, I used 2 JL 10w6 subs though. From the quality of most of the prefab Ram boxes I’m sure they’re meant for some 150 watt subs- not 600 watt subs. From all that I’ve seen separate, the subs being used were 500 watts each and up. Guessing too much force exerted on the boxes. They came apart in the middle, separating the top and bottom. Looked fine from the outside, but when bass hit it would come apart and make a slapping sound.
@@DIYAudioGuy I haven’t had the third brake light leak yet but I do have the front driver sore windshield leak. It’s awesome. Even better since almost nothing that breaks on this truck seems to be covered under the factory warranty. I’ll never buy another Ram.
the only qbomb i'd use are the hp's. they're large (the dual 12 is 2 cuft per sub) they're tuned low (30 hz), and the port is flared. i got the 10" version and planned to use it temporarily, but it ended up being permanent for that installation. first prefab i was ever impressed by. they do need some bracing though, in a bad way. i had a set of k9's in it and they where almost tearing it apart. i think the bed liner was the only thing keeping it from exploding because it did eventually develop a leak.
I have 3 Qbomb boxes..8, 10 and a 10 box with the horn type/front port.....i have to say....it sounds amazing....the only draw back is the cheap mdf material tho.... about 3 to 4 times removal of the sub and the screw port are done with
I always keep an eye out for used to gear on Facebook marketplace and craigslist and every used QBomb box is completely trashed. I think people don't drill out their screw holes.
I feel like the audio community get so caught up on giving a stink eye towards the existence of prefab boxes that we forget that it’s not outside the realm of possibilities for a company make good quality boxes. Plus I feel like we judge prefabs too harshly without realizing that they’re not trying to be the best or win in any SPL lanes, they’re just being there for the newcomers who may have a curiosity or don’t really mind having something like these. After all, it’s like a wise basshead always says: bass is bass! 🔊🔊
...yeah, let's not CONFUSE anybody with whether it's a WELL MADE, or that it is GENERICALLY made = one size fits all.. keep everyone arguing over apples and oranges, so that no one realizes any Sub Driver will ALWAYS perform better in an enclosure MADE exclusively for IT. Ready Made enclosures, are like Fat Chicks in Spandex.... might fit, but never with the desired results..
I’m a Basshead and Bass is Bass is not true , prefab suck bad , I want bass but good deep bass better than high tune , some love high bass notes , I love deep notes
I picked up this box with an Audiopipe 4 stack 12", pushed by a JP23 and I'm very happy with my start up system. Thanks for the reassurance on the box.
I tuned mine to 36hz. Kicker cvx 12 4ohm DVC with RAZR 2500.D set at 2ohms a long with the sub is parallel wired. Minimum on the sub is 1.7sqft. so it works great with no distortion
I bought one of these QBOMB enclosures for a 15" subwoofer a while back and it had a slot port on the side. The cutout for the sub was plenty big and the box did sound very hollow so I just added some bracing to the inside and it sounded fantastic for a Skar EVL 15 with 1500 watts going to it. I did the math on it and it was a 3cuft tuned to about 33hz. I would say if you don't know how to build a box and the specs are close to what your sub calls for, get it. Just add a couple of thick dowels going from one walls across to the opposite wall inside. That will definitely eliminate that hallow sound
Is been two years since you post this but man i have a Q bomb with 2.4 cubic and i have it with a menphis mojo 1212 that is recommended 2.6 cubic feet of air and let me tell you this things sound amazing. They have a formula and is working
My girl wanted a sub so put I skar in a qbomb.... I was actually impressed.. considering I'm used to handmade cust tuned boxes... Also not looking to bad after paint. At least I didn't have to slam you for being a hater. 😂
I actually bought the skar audio box that is 2 cubic feet and it sounds pretty good I was leaning towards q bomb box but liked the look of the skar better I have a kicker comp vr 12 but I am going to a skar vxf 12 now so will be building a custom box later
the scar boxes are very impressive i have become a scar prefab fan actually 😁 they do the best especially customer service!! cant be beat only down side i've encountered cant install rockford fosgates p3's and i am dying to chop em so they will swallow a pair 😎
I've never used one of those. There are a ton of prefab enclosures out there. If I keep getting views and support from my audience I might be able to review more of them.
I have the same Qbomb box in my truck with a Walmart power acoustik gothic 12 with the matching rzr 2500d. For a budget setup it really impresses me it hits cleanly down to 28hz with some rebassed music I’ve played.for a single 12 that cost me about $80 I can’t complain.
Had a prefab walmart box on my power acoustic walmart sub running on fosgate p200-2 wired down to 2ohms and bridged . I switched to the Qbomb....for 80 bucks it was a game changer in my low budget system from the seat of the pants everything was 100 percent t better. Get daily compliment and it's about 200 bucks all in.
I had one for my 2 12's and damn the rhino layer and I had a big slot port and ibwas pushing 2,000 watts bridged I installed the whole thing by myself. Had my woofs slappin and people's heard it from a far distance.
I have this box with a meso 12 running a skar rp1500.1 @ 1ohm . Changed the port to 3"x4.5" to get the tuning down to 35 hz and its violent. Steering wheel shaking bass.
I bought the duel 12 slot port box from them late last year for 80$ it felt light and cheap. While i had a proper custom box built for my he2 15s so i decided to put my old sony xplod 12s on a r2 500x1 fosgate amp in a honda crx at 2ohm, set the gain with a multimeter and I've been listening to different styles of music, rock music sounds the best definitely but not impressed with the enclosure. The sonys do sound very good in a sealed enclosure, so i inverted the sonys and set the headunit to reverse sub output and they sound a bit punchier. I have no clue what the box is tuned to, there was no description. Im looking forward to getting the 15s back in the car. Thanks for doing videos like this. Hope you do the D4S enclosure review.
@@DIYAudioGuy if my subs are inverted hooked to a mono block amp, should i switch the subwoofer phase on the head unit to reverse? Or switch polarity on the amplifier outputs? Or does it matter? Im still learning about all this, sorry lol
Just joined your subscribe I have a 05 Dodge quad cab and I'm looking for putting a box in it and I've been looking at the quad boxes and I was about to buy a quad dual 12-inch sub box with two rockfosgate p3 said it wrong but it's okay I will fix it later and tell you what it is I've had a couple beers tonight just trying to find something good for my truck
Nicely done! In my experience, the Placement of the port in the enclosure, as well as the location you fire the port in the vehicle, can dramatically make the effective tuning of the enclosure play a lot differently in the vehicle and make your overall vehicle response with the subwoofer extremely different than any modeling software can predict. unless you are a wiz at using horzrep 🤓. But also something to consider is the depth behind the sub to the back wall in conjunction with the port being on the same shared back wall can affect the effective tuning as well. But I’m probably preaching the the choir for the most part. Great video though awesome content!!
@@DIYAudioGuy the only program that takes into consideration the box dimensions and room (cabin) dimensions with regard to measurements from said room walls and the enclosures faces/or sides is hornsrep. But it’s very intricate and touchy. But im with you, I’m no expert either. What I think I’ve learned through all my builds has definitely help solidify the math and physics that i come up with when modeling. More importantly, what I’ve learned the most is that when I think I’ve got it all figured out and taken into consideration everything I can to predict the modeling the best, I unknowingly forget something and have to tell myself that I just didn’t get enough info and that’s why the response is not what I wanted it to be. Instead of just saying it’s a mystery. There’s always some type of math or physics behind why it does what it does, and I’m just trying to figure out all those things in my journey!!
My experience with the 2 12s huge port Q Bomb was that it's extremely loud. The box was very loud but didn't hit the lows like my custom box did. I didn't care how the box sounded overall either. It was loud, that's it. I kinda equate it to Flowmasters, they're noisy but not tuned very well.
@@DIYAudioGuy If someone has never had a custom box and only used prefab boxes, they'd absolutely love the Q Bomb because of their limited frame of reference. The extra loudness would be very enticing.
This proves my point. There is NO WAY to predetermine port tuning without knowing the parameters of the driver going in it. Hope people see this video as proof.
Well i am using an 8 string guitar with a 12" guitar speaker, i was looking at the triangle ports tube shaped one with the triangulated internals, Could it do well? The guitar speaker is Warehouse guitar speakers 12" REAPER HP 50.
Dude epic videos I love these keep it up! I’d love to see the pro fab box! I’d love to see skars bed liner box compared. I just bought the other skar box on your review I love it!
The best prefab box I've ever owned is the box that comes with the skar audio evl 5000 watt package. They don't sell it independently. I currently have 2 vfx 12s in it and it bangs hard.
Thank you for the video and much valuable info here. My uncle once said a single phone call is worth hundreds to a person to pay for the info gained. Marconi.
Awesome video. Thank you for testing this. Does your 1.8cft. include for sub basket displacement? Have you thought about inverting the sub to maximize you cubic footage? 😊
That's just the internal dimensions. The amount that you lose will depend on the sub, the amount that you gain from inverting it will also depend on the sub.
Not got one, but I've always heard SUV's tends to have a resonant frequency around 40 HZ. If this is true then this box (size withstanding) is probably marketed specifically for those applications. That 1.8 sounds more like a sealed enclosure size for a some 12's, so could possibly be perfect depending on the woofer used
It doesn't look like it was glued. Is it just stapled together? I heard the sealed version is u shaped stapled nailed together without construction glue within the internal seams.
My guess is the tuning was stated for an "as is" basis. Once a subwoofer is mounted, the displacement of that subwoofer affects the tuning by shrinking the internal volume of the enclosure. Finickey things, subwoofer enclosures.
I have this box for a alpine type r. I find it sounds even better if you stuff the port with polyfill, with this combo. It evens it out a little better IMO.
Nice video! To be honest most prefabs are fine when you have low power or a sub that calls for a small box, Most suffer from inadequate port area for the power being used in the application
Did you notice in the specs on Amazon? They say it's not waterproof. I thought the whole point of the bedliner was to make the box waterproof. I guess maybe it's water resistant? I figure that's important in a Jeep.
@@DIYAudioGuy I didn’t see that in my initial purchase. I mainly got the box because I’m hoping the box can take a bit more beating with things being in the trunk potentially crashing into the box like groceries or tools.
great video, I think it will be good if one day you try the Rockville RQ12TB Single 12" Triangle Ported box, it is 2.2 cubic feet and 35 hz tuning frequency, it seems to have the same build quality as the box in this video
Nice honest review. I still would rather make one but it’s next to impossible being in a condominium. In my case I had a shop make mine and I love it. As far as Qbomb goes, I guess this one isn’t that bad. I’d avoid the dual box with the 4 triangle ports not because of how it looks but because it’s tuned to 52hz I think
I feel like you were biased, almost jealous of this sub box. I think it is a great looking box with a lot of attention to appearance and build quality. However you did admit you hated to say anything good about this awesome enclosure that will help a lot of people get some decent bass in their vehicle without having to spend a ridiculous amount on a custom "pro" box.
You're exactly right, I'm pretty sure I said that in the video. I bought it with the intention of giving it a negative review. I was wrong. It's a great box.
Great video Justin 👍🏼 I appreciate the honesty even with stating that you were not a fan at all of these enclosures. Something big to consider on these is the lack of strength becomes more of an issue when people install much beefier drivers into these single baffle jobs. I’ll end the comment with saying I’d much rather see folks running the D4S Profab prefabs
@@beardedforlife3740 amplifier power is cheap so people tend to just throw power at their problems. Not much thought into the problems that that might cause.
@@DIYAudioGuy I totally agree with that. Like people that throw 2 or 3 batteries at their system and not realize that their stock alt is really the issue. The profab I had from D4S was plenty for the power I was asking for. My next setup is going to be in a custom box not only because they are stronger, but that you can build it exactly how you want it
I own a 2 12" QBOMB enclosure. It gives me a stiffy, whenever I see it and it makes entry level subs sound good. I "MAY" put both my Alpine S's inside it (debating)
One of the biggest mistakes that new car audio guys do is buy the wrong box, not knowing how important it is. The box is just as important as the subs. It is a night and day difference between the right and wrong box
Absolutely. It's so easy to get fixated on the sub because it's just so much more exciting than a rectangular box made out of wood. I've been tring to develop a rule of thumb, for every dollar you spend on subwoofers how many dollars should you spend on the enclosure? 1:1, 2:1? What do you think?
@@DIYAudioGuy I think it depends on what subs you get but if your gonna spend big money on subs then definitely get a custom made box that fits your vehicle and most importantly, is in the specs of the subs. Down4sound is a great site to get an amazing custom made subwoofer box just how you want it
I bought a single 12in ported enclosure from QPower. It does the job, but everything in the product description on Amazon was false. Smells horrible and stinks up my whole car. Also, it's tuned to the high 40s low 50s I believe, which isn't good for a subwoofer
These boxes sound better with poly fill glued to the walls. I never really understood side ports in boxes that wouldn’t be made for spaces like behind seats etc.
@@DIYAudioGuy it worked on one I had. I just use spray adhesive and apply thin layer to the walls. I buy the type that comes in like a roll or folded long piece. It’s like 16”wide 1/2” thick it’s great because it’s easy to cut to length and apply to surfaces with the adhesive. Also doesn’t blow apart like loose poly fill does.
That port open was to small for it to be tune that high. You need a large short port for that high of a tuning. In my country we listen different type of music my box is tune to 45 hz and have max spl at 50 hz where many songs have there bass frequency which is between 40 and 63 hz
i mean, buried in a trunk this wouldn't be too bad. i agree that giant billboard on the top is fugly as is the routing all over the box. i don't mind the rest. i prefer my port to face the same direction of the subs but eh.
you can buy calipers at harbor freight for 20 bucks. much more accurate than using a square to measure wood thickness. I use my cheap calipers all the time. Just a suggestion.
Greaat review. Really loving your channel. I'm glad I've subscribed 👍👍you put out great reviews and knowledge. Just a little different then the other guys. (Not dissing anyone)
It totally depends on the sub u use. If u put a sundown sa in there (so a sub with a bigger motor) the tune of the box will be higher. This is a good box for subwoofers with less power.
I'm getting a RAV4 and seriously considering three kicker cwr 15s to run sealed. I like all kinds of music so how would you rate the transient response of the comp r's ( sealed) I've always preferred quadruple sealed subwoofer setups over two ported on the same power and box volume. I could just run four of the kicker Comp C's 15s in a box facing up as well.
Fun video Justin! Box looks built well. I like it because it has a more pro audio look. Just a different look. What's the sub at the end? Looks like a CT Sounds. They do white everything.
Love the honesty. Kinda weird for tuning to be off by 10Hz or more. The engineers/designers at Q Bomb needs to see this video. Good content 👍

I have 3 Qbomb boxes..8, 10 and a 10 box with the horn type/front port.....i have to say....it sounds amazing....the only draw back is the cheap mdf material tho.... about 3 to 4 times removal of the sub and the screw port are done with
I always keep an eye out for used to gear on Facebook marketplace and craigslist and every used QBomb box is completely trashed. I think people don't drill out their screw holes.
Oh heck yah please get one of those D4S boxes to test out!
Share the video, I need about 50,000 views before I can justify buying one to review.
I feel like the audio community get so caught up on giving a stink eye towards the existence of prefab boxes that we forget that it’s not outside the realm of possibilities for a company make good quality boxes. Plus I feel like we judge prefabs too harshly without realizing that they’re not trying to be the best or win in any SPL lanes, they’re just being there for the newcomers who may have a curiosity or don’t really mind having something like these. After all, it’s like a wise basshead always says: bass is bass! 🔊🔊
Have the infinity primus 1270b s .. they have blown me away for plug and play.. couldn't be happier especially at the cost of the woofer alone. Gems
...yeah, let's not CONFUSE anybody with whether it's a WELL MADE, or that it is GENERICALLY made = one size fits all.. keep everyone arguing over apples and oranges, so that no one realizes any Sub Driver will ALWAYS perform better in an enclosure MADE exclusively for IT.
Ready Made enclosures, are like Fat Chicks in Spandex.... might fit, but never with the desired results..
I’m a Basshead and Bass is Bass is not true , prefab suck bad , I want bass but good deep bass better than high tune , some love high bass notes , I love deep notes
@@LTVX2 lmao 😂
I like having a box because it’s easy to bring in and out
I picked up this box with an Audiopipe 4 stack 12", pushed by a JP23 and I'm very happy with my start up system. Thanks for the reassurance on the box.
Awesome!
I tuned mine to 36hz. Kicker cvx 12 4ohm DVC with RAZR 2500.D set at 2ohms a long with the sub is parallel wired.
Minimum on the sub is 1.7sqft. so it works great with no distortion
👍
I bought one of these QBOMB enclosures for a 15" subwoofer a while back and it had a slot port on the side. The cutout for the sub was plenty big and the box did sound very hollow so I just added some bracing to the inside and it sounded fantastic for a Skar EVL 15 with 1500 watts going to it. I did the math on it and it was a 3cuft tuned to about 33hz. I would say if you don't know how to build a box and the specs are close to what your sub calls for, get it. Just add a couple of thick dowels going from one walls across to the opposite wall inside. That will definitely eliminate that hallow sound
A lot of people just go with a pre-fab box. The trick is to make sure you get one that matches with the sub, and avoid the cheap ones.
The bigger slot port box is the only I used to run with my P3s & Type Rs when I was a teenager, they are quite a bit bigger and are tuned a lot lower.
They are very popular enclosures.
Is been two years since you post this but man i have a Q bomb with 2.4 cubic and i have it with a menphis mojo 1212 that is recommended 2.6 cubic feet of air and let me tell you this things sound amazing. They have a formula and is working
My girl wanted a sub so put I skar in a qbomb.... I was actually impressed.. considering I'm used to handmade cust tuned boxes... Also not looking to bad after paint. At least I didn't have to slam you for being a hater. 😂
Of the three boxes I've tested so far is the best one. It's also the most expensive!
@@DIYAudioGuy your information is amazing btw
I actually bought the skar audio box that is 2 cubic feet and it sounds pretty good I was leaning towards q bomb box but liked the look of the skar better I have a kicker comp vr 12 but I am going to a skar vxf 12 now so will be building a custom box later
I've got a video on the Skar box. It definitely looks better, and it's every bit as good of a box. ruclips.net/video/H3quYaP2Bt4/видео.html
the scar boxes are very impressive i have become a scar prefab fan actually 😁 they do the best especially customer service!! cant be beat only down side i've encountered cant install rockford fosgates p3's and i am dying to chop em so they will swallow a pair 😎
Great video I have a duel 10" Q bomb for my L7 Q class subs and I have been questioning if I need to replace my box.
I'm a big believer in the value of a custom box, but if you're happy with what you have there's really no reason to change.
GREEAATTTT VIDEOOOO !!! Have you ever used a RhinoBox before ? Any opinion on them? If you can a video would be perfect ! Much love and support !!!!
I've never used one of those. There are a ton of prefab enclosures out there. If I keep getting views and support from my audience I might be able to review more of them.
I’ve had a Q Bomb 15” sealed box for almost 2 yrs. and it still performing really well
Awesome!
If I can get 60,000 views on this video I will review a D4S Enclosure: lddy.no/1073r
I have the same Qbomb box in my truck with a Walmart power acoustik gothic 12 with the matching rzr 2500d. For a budget setup it really impresses me it hits cleanly down to 28hz with some rebassed music I’ve played.for a single 12 that cost me about $80 I can’t complain.
That's awesome.
Had a prefab walmart box on my power acoustic walmart sub running on fosgate p200-2 wired down to 2ohms and bridged . I switched to the Qbomb....for 80 bucks it was a game changer in my low budget system from the seat of the pants everything was 100 percent t better. Get daily compliment and it's about 200 bucks all in.
Hell yeah!
I have a Q bomb box with 2 15inch DS 18 EXL (2500 watts) and I love it.
I had one for my 2 12's and damn the rhino layer and I had a big slot port and ibwas pushing 2,000 watts bridged I installed the whole thing by myself. Had my woofs slappin and people's heard it from a far distance.
I have this box with a meso 12 running a skar rp1500.1 @ 1ohm . Changed the port to 3"x4.5" to get the tuning down to 35 hz and its violent. Steering wheel shaking bass.
That is the best kind of bass.
I bought the duel 12 slot port box from them late last year for 80$ it felt light and cheap. While i had a proper custom box built for my he2 15s so i decided to put my old sony xplod 12s on a r2 500x1 fosgate amp in a honda crx at 2ohm, set the gain with a multimeter and I've been listening to different styles of music, rock music sounds the best definitely but not impressed with the enclosure. The sonys do sound very good in a sealed enclosure, so i inverted the sonys and set the headunit to reverse sub output and they sound a bit punchier. I have no clue what the box is tuned to, there was no description. Im looking forward to getting the 15s back in the car. Thanks for doing videos like this. Hope you do the D4S enclosure review.
These things have definitely gotten more expensive as lumber prices have gone up.
@@DIYAudioGuy if my subs are inverted hooked to a mono block amp, should i switch the subwoofer phase on the head unit to reverse? Or switch polarity on the amplifier outputs? Or does it matter? Im still learning about all this, sorry lol
@@ckillac5258 either or, it should not matter. Personally I would swap it at the speaker terminals, but that's just me.
@@DIYAudioGuy thank you sir
Just joined your subscribe I have a 05 Dodge quad cab and I'm looking for putting a box in it and I've been looking at the quad boxes and I was about to buy a quad dual 12-inch sub box with two rockfosgate p3 said it wrong but it's okay I will fix it later and tell you what it is I've had a couple beers tonight just trying to find something good for my truck
I had a few beers last night myself. Had to stop responding to comments because I was just pumping out gibberish.
Nicely done! In my experience, the Placement of the port in the enclosure, as well as the location you fire the port in the vehicle, can dramatically make the effective tuning of the enclosure play a lot differently in the vehicle and make your overall vehicle response with the subwoofer extremely different than any modeling software can predict. unless you are a wiz at using horzrep 🤓. But also something to consider is the depth behind the sub to the back wall in conjunction with the port being on the same shared back wall can affect the effective tuning as well. But I’m probably preaching the the choir for the most part. Great video though awesome content!!
I am not an expert on port loading. I guess I need to try some different port configurations and see what I can learn.
@@DIYAudioGuy the only program that takes into consideration the box dimensions and room (cabin) dimensions with regard to measurements from said room walls and the enclosures faces/or sides is hornsrep. But it’s very intricate and touchy. But im with you, I’m no expert either. What I think I’ve learned through all my builds has definitely help solidify the math and physics that i come up with when modeling. More importantly, what I’ve learned the most is that when I think I’ve got it all figured out and taken into consideration everything I can to predict the modeling the best, I unknowingly forget something and have to tell myself that I just didn’t get enough info and that’s why the response is not what I wanted it to be. Instead of just saying it’s a mystery. There’s always some type of math or physics behind why it does what it does, and I’m just trying to figure out all those things in my journey!!
My experience with the 2 12s huge port Q Bomb was that it's extremely loud. The box was very loud but didn't hit the lows like my custom box did. I didn't care how the box sounded overall either. It was loud, that's it. I kinda equate it to Flowmasters, they're noisy but not tuned very well.
I like that analogy.
@@DIYAudioGuy If someone has never had a custom box and only used prefab boxes, they'd absolutely love the Q Bomb because of their limited frame of reference. The extra loudness would be very enticing.
They have about six or seven different Flowmasters and you can listen to the different sounds somewhere here on RUclips
This proves my point. There is NO WAY to predetermine port tuning without knowing the parameters of the driver going in it. Hope people see this video as proof.
I've almost reached that conclusion, everything I've designed, all the math that I've done. The DATS always says it's tuned lower than estimated.
@@DIYAudioGuy I'm sure. Design and build a box around a specific drivers T/S parameters and it should be spot on or super close.
I’m going to need one of those digital tape measures
There is a link to one in the description.
Great you to point people in the right direction who really don't want to go custom. Love the show and keep doing what you doing.. 👍👍👍
I'm having the time of my life, as long as people keep watching I'm going to keep filming!
Well i am using an 8 string guitar with a 12" guitar speaker, i was looking at the triangle ports tube shaped one with the triangulated internals, Could it do well?
The guitar speaker is Warehouse guitar speakers 12" REAPER HP 50.
I think that would be a bit of a mis-match. Guitar cabinets, even for bass guitars, are usually tuned a bit higher.
What's better the skar or the q bomb box for the single 12? Thanks.
Dude epic videos I love these keep it up! I’d love to see the pro fab box! I’d love to see skars bed liner box compared. I just bought the other skar box on your review I love it!
Also take a look at the harmony box it’s only $75!
Glad you liked it, I will have to give that harmony box a look.
The best prefab box I've ever owned is the box that comes with the skar audio evl 5000 watt package. They don't sell it independently. I currently have 2 vfx 12s in it and it bangs hard.
Awesome!
Thank you for the video and much valuable info here. My uncle once said a single phone call is worth hundreds to a person to pay for the info gained. Marconi.
Thanks
Awesome video. Thank you for testing this. Does your 1.8cft. include for sub basket displacement? Have you thought about inverting the sub to maximize you cubic footage? 😊
That's just the internal dimensions. The amount that you lose will depend on the sub, the amount that you gain from inverting it will also depend on the sub.
Not got one, but I've always heard SUV's tends to have a resonant frequency around 40 HZ. If this is true then this box (size withstanding) is probably marketed specifically for those applications. That 1.8 sounds more like a sealed enclosure size for a some 12's, so could possibly be perfect depending on the woofer used
Matching the woofer and enclosure to the car is really tricky. Whenever I get that figured out I'll make a video on it.
@@DIYAudioGuy, Ok, Like I said, that was just what I heard. Not a basshead, I like to hear all the music, but also not a Q maniac either
I'm doing a build and install today for 1 of them exact trucks
Just got to keep the box dry. That rear brake light tends to leak. ruclips.net/video/7UNgvvfYuUI/видео.html
I appreciate that you can say you dont like it. But also it performs well so its a good box
That is my honest opinion.
I just finished designing my dual bass reflex box and can't wait to put it together! Maybe you can do a vid on those.
My video to do list just keeps getting longer!
It doesn't look like it was glued. Is it just stapled together? I heard the sealed version is u shaped stapled nailed together without construction glue within the internal seams.
My guess is the tuning was stated for an "as is" basis. Once a subwoofer is mounted, the displacement of that subwoofer affects the tuning by shrinking the internal volume of the enclosure. Finickey things, subwoofer enclosures.
When the enclosure volume decreases the tuning frequency increases.
You got me sold on buying one of these for my 10 inch JL audio.
If you're going to go with JL I would recommend having a shop build a custom box.
I have this box for a alpine type r. I find it sounds even better if you stuff the port with polyfill, with this combo. It evens it out a little better IMO.
Thanks for the tip!
I also have this box for an alpine type r, the r2-w12d4. What amp are you pushing it with?
Love your commitment and honesty, great videos, please keep the content coming.
Nice video! To be honest most prefabs are fine when you have low power or a sub that calls for a small box, Most suffer from inadequate port area for the power being used in the application
Absolutely. Amplifier power is cheap so people tend to just throw power at their problems.
What’s funny is, I have basically the same setup in my Jeep Grand Cherokee. I too was surprised with this box.
Did you notice in the specs on Amazon? They say it's not waterproof. I thought the whole point of the bedliner was to make the box waterproof. I guess maybe it's water resistant? I figure that's important in a Jeep.
@@DIYAudioGuy
I didn’t see that in my initial purchase.
I mainly got the box because I’m hoping the box can take a bit more beating with things being in the trunk potentially crashing into the box like groceries or tools.
4.8 Hole Near Back At Edge Hole. No Tube NeeDed.
Great video appreciated! Could you fiberglass resin the inside to get more solid sound
II honestly don't know, but I don't suspect it would help.
great video, I think it will be good if one day you try the Rockville RQ12TB Single 12" Triangle Ported box, it is 2.2 cubic feet and 35 hz tuning frequency, it seems to have the same build quality as the box in this video
Sounds like a good box.
I have a qbomb in my Jeep Wrangler for my 8” Image Dynamic idq with a zed audio amp, it bumps, no lie
That is a nice sub, I really need to try one.
@@DIYAudioGuy I was shocked at the fact it was made in USA 🇺🇸
Wooden port long enough to reach opposite wall behaves like curved port, so it effectively longer, hence the lower Fs.
You’re gonna run outta room quickly testing all these pre fabs! Great video
I ran out of room a long time ago!
Give aways!!!! 😆
Nice honest review. I still would rather make one but it’s next to impossible being in a condominium. In my case I had a shop make mine and I love it. As far as Qbomb goes, I guess this one isn’t that bad. I’d avoid the dual box with the 4 triangle ports not because of how it looks but because it’s tuned to 52hz I think
That's the danger of doing a review like this, people might see it and think that QBomb is OK, I only said this one is okay.
Do you mind me asking how much you paid the shop for your box?
I feel like you were biased, almost jealous of this sub box. I think it is a great looking box with a lot of attention to appearance and build quality. However you did admit you hated to say anything good about this awesome enclosure that will help a lot of people get some decent bass in their vehicle without having to spend a ridiculous amount on a custom "pro" box.
You're exactly right, I'm pretty sure I said that in the video. I bought it with the intention of giving it a negative review. I was wrong. It's a great box.
Great video Justin 👍🏼 I appreciate the honesty even with stating that you were not a fan at all of these enclosures. Something big to consider on these is the lack of strength becomes more of an issue when people install much beefier drivers into these single baffle jobs. I’ll end the comment with saying I’d much rather see folks running the D4S Profab prefabs
I still don't like the box.
I had a D4S profab and I thought it was a good box. They even tell you they aren't recommend over a certain power level
@@beardedforlife3740 amplifier power is cheap so people tend to just throw power at their problems. Not much thought into the problems that that might cause.
@@DIYAudioGuy I totally agree with that. Like people that throw 2 or 3 batteries at their system and not realize that their stock alt is really the issue. The profab I had from D4S was plenty for the power I was asking for. My next setup is going to be in a custom box not only because they are stronger, but that you can build it exactly how you want it
Those thing's are expensive though even more than the Bobby gately boxes.
Ordered one of their boxes recently, claimed to be 3/4….. yeah only the front is 3/4 the wrest is 1/2 with bed liner….
I own a 2 12" QBOMB enclosure. It gives me a stiffy, whenever I see it and it makes entry level subs sound good. I "MAY" put both my Alpine S's inside it (debating)
One of the biggest mistakes that new car audio guys do is buy the wrong box, not knowing how important it is. The box is just as important as the subs. It is a night and day difference between the right and wrong box
Absolutely. It's so easy to get fixated on the sub because it's just so much more exciting than a rectangular box made out of wood. I've been tring to develop a rule of thumb, for every dollar you spend on subwoofers how many dollars should you spend on the enclosure? 1:1, 2:1? What do you think?
@@DIYAudioGuy I think it depends on what subs you get but if your gonna spend big money on subs then definitely get a custom made box that fits your vehicle and most importantly, is in the specs of the subs. Down4sound is a great site to get an amazing custom made subwoofer box just how you want it
I bought a single 12in ported enclosure from QPower. It does the job, but everything in the product description on Amazon was false. Smells horrible and stinks up my whole car. Also, it's tuned to the high 40s low 50s I believe, which isn't good for a subwoofer
I just got an Sonix enclosure stage two. Seems decent for the price.
Yea, those are solid.
These boxes sound better with poly fill glued to the walls. I never really understood side ports in boxes that wouldn’t be made for spaces like behind seats etc.
You are the second person to say that in the comments. Polyfill is cheap, I might have to give that a try.
@@DIYAudioGuy it worked on one I had. I just use spray adhesive and apply thin layer to the walls. I buy the type that comes in like a roll or folded long piece. It’s like 16”wide 1/2” thick it’s great because it’s easy to cut to length and apply to surfaces with the adhesive. Also doesn’t blow apart like loose poly fill does.
Rocker fosgate P3 punch 12" is the best for a qbomb
Your crazy that box looks great but at least you gave it a fair shake
Glad you enjoyed the video.
Great review. Thank you, I've been thinking of getting one for two 10's. Soundstream tarantula.
Glad to help.
Sounds like once you corrected the port length to include it using the back of the box and after woofer displacement it landed at a good tuning.
Yep.
This box is a masterpiece for a Rockford p2 @2 ohm or a cp amp
👍
That port open was to small for it to be tune that high. You need a large short port for that high of a tuning. In my country we listen different type of music my box is tune to 45 hz and have max spl at 50 hz where many songs have there bass frequency which is between 40 and 63 hz
So which is the best single box for a 12” sub? Love your videos
This one: lddy.no/1jwux
Its certainly ot tue for 43 hertz at the size of the box for my 12 inch cerwin vega i run a 2.5 cubic feet sealed box tune to 40hertz
Skar triple 8 heavy duity try that one it has the bed liner spray do not the carpet model
i mean, buried in a trunk this wouldn't be too bad. i agree that giant billboard on the top is fugly as is the routing all over the box. i don't mind the rest. i prefer my port to face the same direction of the subs but eh.
Yea, not a fan of the look.
I have two 10" soundqubed in a qbomb box tuned to 30hz kerf. It slams! People hear it and can't believe it's a prefab.
Yeah, I was pleasantly surprised.
Justin great video . you should test these boxes in a van. love your content.
Best van for the win.
I have two jl audio 12w6-D4 which box would you recommend
Have a local shop build you a custom box.
you can buy calipers at harbor freight for 20 bucks. much more accurate than using a square to measure wood thickness. I use my cheap calipers all the time. Just a suggestion.
Now that you mention it I do have a set calipers. I never think to get them out. They just sit in a drawer and take up space.
Greaat review. Really loving your channel. I'm glad I've subscribed 👍👍you put out great reviews and knowledge. Just a little different then the other guys. (Not dissing anyone)
If everybody was exactly the same then RUclips would be a boring place.
@@DIYAudioGuy yea true. Very true
It totally depends on the sub u use. If u put a sundown sa in there (so a sub with a bigger motor) the tune of the box will be higher. This is a good box for subwoofers with less power.
Yep.
I got a 12” kicker compVR will that sound good in this box?
I'm getting a RAV4 and seriously considering three kicker cwr 15s to run sealed. I like all kinds of music so how would you rate the transient response of the comp r's ( sealed)
I've always preferred quadruple sealed subwoofer setups over two ported on the same power and box volume. I could just run four of the kicker Comp C's 15s in a box facing up as well.
I have not tried it sealed yet.
Fun video Justin! Box looks built well. I like it because it has a more pro audio look. Just a different look. What's the sub at the end? Looks like a CT Sounds. They do white everything.
That's going to be September's surprise (or you can just look at the links in the description).
