Can you just sell me one? 🙏
what about the cable wiring?
So frustrating not hearing the actual sub, having the music overlaid makes me think it doesn't work at all.
No crossover??
Im confused .. should i laugh or cringe at the intro?
Yes 😁
@@Toid LOL!
Both. Lol
I don't know, but he keeps calling 8 inches TINY...
Definitely cringe
the music does not come from the box, it comes clearly from the audio file uploaded to youtube
no shit
You are totally right, Listen to Ship Wrek featuring Essy, Fool's Gold. Any recording using microphones would have added phase shifting, ambient environment artifacts and noise. Man, be honest and admit you synchronized your video with a track!
I like how you guys have a sense of humor. We do a ton of custom work ourselves. I'm glad I came across your Channel. Look forward to the next video
Sweet. I'm going to build this for my desk.
Many thanks for picking a beat with a sick af bass line!
Reminds me my Totem Storm in my living room. The best 8in sub I ever had, even best sub period.
we use that wax on all our tablesaws etc, outfeed tables, works great. its so nice to have a nice slippery surface when ripping 4x8 3/4 ply like birch
So I'm using 4 of these subs tuned to 34hz in a ported box. They do every bit of that. Great little subs, was very impressed.
They really are super impressive subwoofers for their size. I never used them due to their price. I always thought, man I can get much cheaper and bigger. But there is a reason these cost more. They are insane! Sounds like you built a sweet project!
Can you share the measurements of the ported box ?
What a awesome video. Once again nice work.
That opening line is great. HAHA classic.
Nice build! Something to try if you haven't: Before assembly, saturate your wood with boiled linseed oil and let sit 15 minutes; then wipe off the excess. Then apply your wax!. I was going to build some Overnight Sensations for my desktop and want to add this for a mini-sub.
What does the boiling linseed do?
Thx
@@ds1919ds1919 Gives wood "character" by bringing out the grain and enhancing the color.
Good job. 🔈👍
I use Johnson's paste wax on my cast iron, but that stuff reeks for anything you're gonna bring into the house. Pick up some Walrus Wood Wax or something similar and you won't regret it. Heck, I make my own from carnuba wax, beeswax, and orange oil. It smells great and is completely non-toxic.
I built mine using a 6.5 " sony sub feel it hitting my heart😁😁 awesome build bro
Enjoy it!
I tried the exact same thing with those same drivers but tuned to 42Hz in a small bookshelf. In that enclosure, the TB just hammered the PR's and ran them completely out of excursion.
Cool man
Very nice Sir👍
I use the furniture wax all the time on my build, it is easy to use and it puts a durable finish on the speaker.
I use that paste wax on my table saw, router and some wood products as well.
It is for sure my favorite.
These are cool. Next you need to build one using their smaller subwoofer the 3" Might be a good match for some small book shelf speakers.
That test at the end was so satisfying to watch.
Superb
I built a very similar sub with the same passive radiators and the non neo version of the tang band 5 1/4" Obviously I am not the only one to pair these components. It really does sound great... I use it every day under my feet in the design lab. Super full bass from a very small enclosure. Just FYI the non neo version is a much better sounding sub I have done several builds with each and side by side the neo version sounds weak.
I’m doing a similar design but using the W6-1139 and 2 SB Acoustic PR’s. The WinISD graphs all look great, but SB have suggested that ringing could be an issue. Others have said not to worry about it.
Did your graphs show that ringing could be an issue with this design and, if so, can you detect any?
Thx for the vid. I’ve used those subs in a number of builds. They rule! Does the build log give the weight added to the PRs to tune them? Should really do a video specifically explaining how to tune with PRs
The build log does offer that. I completely agree these subs are beasts. I may have to work on a passive radiator tuning video sometime. Thanks for the great idea.
I'm going to try this out but was thinking of saving $30 by using the SMF and making the box 9" instead of 8". Will this create a big difference in the tuning? Other possibility is mounting the radiators on the outside but they don't look as nice that way.
Making a "6 subwoofer with a sub I found at the scrapyard. Pretty good sub actually looked barely even used
Passive Radiator donot has high SPL as compares to ported enclosures but these only require small space, which is its quality😊
Sounds like a direct recording, no acoustics etc. If it's not a direct recording, what are the treble speakers and are they close to the mic? The closer the mic, the more accuracy in how the speakers sound (and less acoustic influence).
agree.....
I think it was more of a functional demonstration than an actual acoustics test. Knowing what to expect, one can put on some decent headphones and watch how the woofer behaves when low freqs are introduced.
Have you tried building the tang band 4" sub kit build? It's also sealed and very small
Fantastic, thanks for building and sharing! What music track was that you demo’d with?
Fun little project.
Did you take measurments?
Sounds like it breaks up really badly around the resonant frequency, and sounds like the passives resonate together at a different frequency than the driver.
That was a straight up as seen on tv intro for this sub! Classic 🤘🏼
This sub seemed like it was super impressive for the size
Haha, it was! Lol. I'm glad you enjoyed it.
Nice
This thing made my room shake while playing trough my phone! Nice build! I'm planning on building a sub with passive radiators, but a little bit bigger.
Sweet! I hope to see it. Feel free to share it on the forum.
That opening 😂 man I wish I had a CNC... That's awesome. Hopefully I'll have a dedicated shop soon vs the garage, I'll invest in some more tools then. That turned out pretty sweet bud.
Haha, thanks man. I can't wait to see what you come up with for a workshop. Your stuff is always top notch.
Is this better to use one passive radiator instead of two?
As earthquake sound corporation uses only single passive radiator.
Please help me.Thanks
Friend you really need to get some pusher sticks or better yet pusher pads for your table saw. It is so easy to lose a finger or mess up a hand in the blink of an eye. Google table saw accidents. Or at least the people wanting to copy your design ought too.
entityofme the way a lot of blade guards are and the knife deal..... it can end up being more dangerous. I took mine off after shit got caught.
I made zero clearance inserts. That is one of the biggest things a person can do to improve safety.
Push blocks and push sticks ( two ). Are critical also.
If a person wants a cheap diy that you can toss when it’s time, you can take some 4”x 10” or so mdf then spray glue the drawer liner stuff that grips real good, then trim off extra.
That way you can hold down flimsy stuff like 1/4? Or abs etc and set the blade so it’s just cutting through material and hitting the drawer liner if you need to hold it down nice & tight as it goes over blade
Lynn Poole most important thing is to be wide awake & aware! No distractions no hearing protection so you know your environment better, safety glasses..... super tight fitting gloves that have better grip than your skin on your fingers if that helps you have improved grip. (Some will try to argue this but they don’t get it....I’m not talking “leather work gloves” that are all loose & shit. Either those gloves that are dipped on the face of hand if they fit ultra tight or I have disposable gloves that have excellent grip. There is no way the table saw is catching these and sucking you in.....one more time for the people in the back... I said TIGHT! If you can’t pick a booger out your nose wearing them, they are not tight enough!
entityofme you are using you blocks or sticks. Also proper technique when pushing sheets through. You don’t push straight into the blade, you push at the fence and forward.
I use tablesaw almost daily. Ridgid r4511 granite top saw. Have not had an issue or kickback in a decade.
@@caseytbss if I were you, I'd shut up right about now.
What you're saying is dangerous af, and you should never give out that advice anymore!
Only old ass idiots would ever say to not wear hearing protection!
Also shut up about not using a riving knife or splitter.
It works wonders and if you manage to have that catch, then you're some kind of special that shouldn't be using a table saw.
Eye, mouth and hearing protection is a must use, not a suggestion.
A riving knife or splitter is also aust have, unless you're doing specialty cuts.
Let me guess, you also think it's fine to use the fence and miter gauge at the same time?
Hey man, how is this for a home theater subwoofer in a small room? I probably gonna have to make two as my receiver has two subwoofer outputs and they're passive.
If using 2 w5-1138sm, can we simply double the volume inside with 4 pasive radiators? Does the 2 subs need to be plug in serie or parallele?
Where can I contact you? I try to revister to your webpage but I never recieve the email activatuon enven after multiple time. . .
Thank you
Do passive radiators need to match the active speaker size? Could you use the Dayton Audio low profile 6 inch with the same radiators?
The passive radiators need to have twice the volume displacement. If you follow the link above to the right up about this, the comment section talk about how to figure that out. I also did a video on how to design a passive radiator setup, found here: ruclips.net/video/sG_8qgSjUqE/видео.html
I built the hivi 3.1's and love them! Altho they have decent base for what they are, i def need more base.. Do you think something like this would match up with them? Looking for something small/inexpensive.. If not, what would you recommend? Really dont want to spend $300, thinking $100-$175 range.. Thanks brother!! Love your channel!!
This could be something to consider. You could also consider the Front Slotted Voxel, which goes lower and would be cheaper to build. The main difference, is a port versus passive radiator and it's size. Still a small footprint though. toidsdiyaudio.com/product/front-firing-voxel-subwoofer-plans/
How'd I get to diy subwoofers? I was looking for prebuilt floor standing speakers.
There's theory behind those cubes!
I'm building this for my son for Christmas. Going to use the Lepai LP210PA. For the highs and mids, going to use Dayton Audio DAEX32EP-4 Thruster attached to 2- 24" x 48" accoustic ceiling tiles.
Sounds like a great project!
@@Toid should I add poly fill?
@@nperry77 There is no real reason to, but you could throw a handful in if you want to.
@@Toid let me give a tip to anybody else trying to build this. Don't unintentionally used 3/4 inch instead of half inch and expect the measurements to come out correctly :-)
@@nperry77 oh man that stinks. Sorry to hear that.
If I have more Space, like 45m2 is it fine or maybe it is worth looking for sub project with 8 inch woofer? Honestly this particular project intrigues me
Would the ferrite version of the W5 work if i surface mounted the PR's?
If i make this base in a different form but same amount of room (litres) will it work the same? or will it perform different?
Great. Hey I need some help with understanding how to select a passive radiator and if the recommended volume sizes for sealed cabs for the active speaker are the ones to be considered for the use of them. Thanks.
You should consider joining the forum. That's where we tackle topics like this. www.toidsdiyaudio.com/community
I will right now.
This has roughly the same internal volume as voxel. Can you can confirm that instead of PRs i can use a port and just use a pvc elbow so i can it can fit inside without the opening getting too close to the internal wall??
Can the passive radiator be on the back to hide it from view?
Hi,
Thanks for this info do you think 1*PR is sufficient to handle one W5-1138SMF subwoofer, and one builder from PE uses 2 of ND140 for a single W5-1138 he said the W5 maxes them out. What do you think?
There might be one passive radiator that will handle it, but not these passive radiators. These passive radiators will be maxed out if you do any bigger of a box. So if you try tuning lower and going with a bigger box, these won't work with it. But they do work with this particular volume.
@@Toid BTW what is the internal volume? 7-8litres, or 0.29-.0.33cuft.
@@yttean98 most if this information is in the build log linked above. I would suggest reading it, so it'll give you a better understanding of what will and will not work. This internal volume is around 0.175
Great little woofer. I like it. Greetings from Franks Werkstatt der Lautsprechertechnik
Hi, did you do a video on these small bookshelf speakers in the background from the intro?
They seem interesting
Those are pretty cool. I'm still working out the crossover for those. They will be on the channel soon
123Toid sounds exciting!
I’m building a similar speaker just with a Vifa Ne65 full range driver on the front.
I chose a 6db crossover because both drivers are rather flat beyond their used range and the parts are kept fairly small.
Have you had any specific plans for the crossover of your speaker yet?
@@speakertoni2680 no. I'm still working on it. Sounds like a great project! Feel free to share it in the forum if you'd like. We love seeing projects over there.
123Toid sure, which forum is it?
@@speakertoni2680 www.toidsdiyaudio.com/community
I'm learning this stuff from Y.T.
What is the advantage of the passive radiators Vs a sealed enclosure?
Passive radiators act similar to ported enclosures. That means they have the ability to play lower and louder. The vantage of them over a port is you don’t have to worry about port noise and the box is smaller. The disadvantages over a ported system is they don’t tune as low and have a steeper drop off.
I'm sorry for not knowing better but it does that need to be crossed over at a low frequency?
Hi. What amplifier would you recommend for this? Regular amp dont have a crossover or low pass filter.
I'm building this now. I chose Lepai lp210pa 2x30w + 60w 2.1
@@nperry77 can you share your build? Where can I see it?
Can't wait to swing by and listen to your creations.
Since you have the tools a frequency sweep would it be nice
The intro reminded me of "Fun with Flags" in TBBT
If only Will Wheaton had walked in...
Do you still have the build plans for this? thanks, the link you gave to the plans is dead
Lol that intro was so awkward but great! Thanks for the video well done.
Umm cross cutting on a table saw? Do you like the way your fingers are right now or are you interested in maybe removing some of them? It's called a cross cut sleed. Don't use the fence when cross cutting. Your piece of wood could bind-up against the fence and twist bringing your fingers with it. You might also try some push sticks.
Ahhhhhhh!!! Earthquake!!! 🤣😂🤣
Would it make sense to use them stereo with 2 lepai active modules?
Absolutely. Could power these with a little single channel amp if needed as well. Plenty of 50+ watt mini modules that will make this thing sing
How much weight did you add to the passive radiators
Cute girl great box
Am I mistaking. It does not feels live recording through speakers. Like original track added to video. I cannot differentiate.
Fast enough for Magniplanars?
Is that the Lyra-8 in the intro? :O
*Hears small package joke, subscribed* lol
How's this compare to the Voxel which uses a similar driver?
It's similar in they can both use the same driver. The difference is this one uses passive radiators and is tuned higher. If you need the lower tuning, the voxel is a great design. I even redesigned it with a front firing slot port to cut down on the port noise. The Port is the one downside for the Voxel. depending on how much power you're giving it, you can definitely get it to chuff. Having said all that, I think it's a fantastic sub, this is just another option and how to use that particular sub driver.
Cool little project Nick! I see you are using Johnson's Paste wax in the video, did you ever try it on the table saw top? Here's another tip I hope will help, next time you buy a router bit for the CNC, get a down-cut spiral. It will leave a much cleaner finish from the top. Added bonus, it puts downforce on the part as it's cut (useful if you ever decide to switch over to a vacuum table).
Thanks Kevin. I actually plan to get a downcut bit from tools today. Thanks for the tip! I had been using a compression router bit, but it really wasn't working the way I thought it would.
I can not Understund how this subwoofer working without air Window, Can you explain me please, if i use two speaker wofer.. there is problem with speaker or box?
Port* and u don't need port u can use sealid box or with a passive radiator
Stanislavskij actor studio!
Out of pure curiosity, what would a 200db at 20hz clean, build look like 😂
Good video. What make is that table saw???? Hope you use good dust collection...
It's a powermatic 66 hooked up to a jet dust collector.
@@Toid Very good. Is your shop in a basement? I share mine with a car.
@@DavidALovingMPF102 I'm lucky enough to have my own workshop. Although it's just a small shed in the back yard.
Great little build! Correct me if I'm wrong, but i thought the passives should be the same diameter or bigger than the main driver.. Am I wrong?
That is a common misconception. Passive radiators should have twice the volume displacement. The volume displacement is SD x Xmax. You can use about any size as long as you have at least twice the volume displacement as the original driver. Most people simplify this as saying you need two passive radiators the same size as the active drivers, but that just isn't true. If you have a passive radiator with the same SD and same size as the active with twice the xmax, you would be fine. You can check out this video on passive radiators as well, if you want to learn more about them: ruclips.net/video/ISCdx73hRxo/видео.html
So how would a tower of those sound?
Could the passives be used in a modified dinas build??
Not these. But I have a build working on that as we speak.
Hello, I can't download the free plans, can you send me the link please. Thanks!
toidsdiyaudio.com/2020/02/06/mini-earthquake-an-8-cube-of-bass/
Can any 8" Subwoofer with similar T/S parameters be used?
Not with this design
Drop the BASS!
did that canceled each others, because different phase?
You guys are cute together.
With horn woofer it will amplified more sound
Nice build. Like to see it with a 6.5 too
I wonder if this could be 3d printed
What type of wood did you use
Baltic Birch plywood. I think I mentioned that around 55 seconds in.
Lol
Servo ?
Bug thing with small package 🤣🤣🤣🤣
How can i hear stereo full range signal from a mono subwoofer? ?
What do you mean?
@@Toid you demonstrate your subwoofer at the of the video right? yet I hear fullrange signal in stereo.. how can that be? one would expect to hear roughly 80 hz on down in mono ;)
Because it's not live recording? Even if it was, it would most likely be part of a system with mids and highs somewhere on desk.
@@cekpi7 awwwww lies lies lies! :P
@@Reefgc Most mics wouldn't be able to capture it's response properly anyway, or listeners setup wouldn't be able to produce it.
You designed a very nice 8" sub, now a really tiny 5", so it seems that a 6" 1139 based sub is the next logical step to fill in the gap.
Make a horn it will increase bass at least 40%, like in tweeter horn type
Sound test please
Is this louder than the 8 inch dayton sub?
The 8 in would be louder. This is more built around size.
@@Toid ok thx
Mini cube = mini bass 🤣
Trying to decide if the intro was corny or cheesy?
Hmmm
Cheesy Corny Bread?
Lol, it's definitely both.
123Toid lol! Keep up the good work! I need a neat enclosure idea that uses up to 4 of the tang band w6 6.5 ferrite drivers. If you got any neat ideas? I’m open to using 2 on each and making some towers using them as the woofers..... I also have a pair of the W4 mids/woofers that are the composite plastic frame & have the bolt studs around the lip that go in between each mounting screw. They are neat speakers, called a 4” but they are bigger than most 5.25” speakers.
