I'll never go ported, sealed sounds so much better. Its tighter, punchier, more accurate bass and it has a far better general response across frequencies vs a ported box that sounds baggy and is tuned to sound loud on a very narrow frequency band
In most instances a given drivers optimal ported volume is much larger than it’s optimal sealed volume. That’s why there’s usually a much larger dB difference between the two enclosure types.
Nice video! I love that old school Fosgate setup too, and it's awesome that you've passed it on. Seems like the best part about a hobby is passing it on to your children :)

What I've noticed is that, to gain 3db or more from the subs in a ported enclosure. You need an enclosure that's ridiculously large. As in like 2x larger. I prefer sealed honestly. My 12s are in a sealed enclosure.
This agrees with the iron law that of course more space makes more Bass. I've always loved triple or quadruple sealed setups because you can fit twice the drivers in the same amount of air space while maintaining a tighter more accurate sound that has more impact. I'm actually headed out to the garage right now to start building my sealed enclosure for three 12-in stereo integrity SQL 12s. They are the best deal out there by a mile if you want ultra high performance xbl2 motor sealed subwoofer setups. Ported can move a lot of air sure but you're never going to get that blur your eyeballs Hammer to the chest at a concert perfect drums feeling out of them.
@@XX-121 if you run enough power on sealed it's still loud but has that concentrated impact and clarity and transient ability that ported doesn't it's worth running twice the power to a sealed setup
I ran that setup for the majority of my rookie season with NADBL, those oldschool subs helped carry me to an undefeated rookie season. Thanks for watching and commenting.
I actually felt my sealed box hits harder than my recently installed ported box. But mainly I see the gains going to a ported enclosure is air cooling and venting the heat out of the woofer which will give you more life out of your electronics! I’ll never buy a sealed box ever again
Nice video reminds me of back in 1998 when I was running 4 punch power DVC 15 with 2 punch power 1000s in a 1987 merkur xr4ti competing in spl competition as a privateer going up against all the car audio shops good stuff man
I have had so many systems but easily my favorite was back when I had a pair of Fosgate DVC 12's in a sealed box running off a MTX Black Gold amp. I just haven't been able to find a sub with the same force factor. I went to 4 12" JL audio 12w3 running off twice the power. It was loud but nothing even close to the beating the 2 Fosgate DVC 12's would give you. I wish Rockford Fosgate would release a classic series of car audio where the legends that made the company would be available. I would buy multiple systems just to have backups of everything.
But what sounds better? I had a sealed box with two Rockford Fosgate punch 12s and a 700watt Rockford amp and it was some of the tightest and cleanest bass and would put out 144db without any stress.
I got nostalgic watching this. Last time I saw 2 Punch Power DVC 15s I installed them in a navigator, custom box with mirrors inside using Aeroports pushed by an Orion HCCA 250. It was humping!
I’m hoping my kids will love this also give us more to do together… I’m hitting 110 with just a random set up. None name brand system with Pioneer radio touchscreen
How old are you bro!!!!!!???? Rob??? Cause shes 15 i think she just turned it and your sick asfuck... If i was steve ill beat the shit out of ypu in fact if i knew where ypu was at id still beat the shit out of you... Dick face...
This question might have been asked and answered already in the comment thread but..Would you say in a music listening scenario instead of a db scenario, the sealed gives a better ,tighter, accurate bass response and is worth the loss of 1 plus some change db?? Thanks if you feel like answering! 👍🙏
Since nobody answered I will I absolutely know that the flatter response and better transient response of sealed makes it far superior for me but then again I'm a 46 year old musician that's been a lot of time on a metronome. Also the earthquake reproduction characteristic of sealed where it literally displaces a section of air in your vehicle that is heaven and a ported does not do this it just fans around a whole bunch of air from the port and sub. It never has that instant earthquake shock type impact to it and I like that.
You've probably gone on to a different setup by now, but I wonder what your air speed is in those ports. They might be compressing your output. Also, porting increases the volume at a specific frequency, so it's not necessarily 'supposed' to be +3dB everywhere in the range. Your port tuning and your listening area's tuning are two very different things.
She is running a Punch X crossover which gives a decent bump in RCA signal voltage. I run a Rockford PA1 preamp in my jeep and can get above 8v clean signal to my amps. Definitely makes a difference having strong signal and a lower noise floor. Thanks for watching and commenting!
Thanks for watching and commenting. I'm assuming if the ported side were tuned low enough it could be quite interesting to see. I did do a video showing the excursion side by side playing 20hz - ruclips.net/video/gMjPjDh4bK4/видео.html

I’ve moved my boxes around my trunk just to see if the box is facing your back you get different thump or set up as close to the rear as you can speakers facing the rear.
I had a similar situation with my triple audiobahn alum10q's. Friend if mine has 3 as well. Mine are sealed and his is ported and we can not find any major differences between the outputs. The difference is that he rebuilt his with dual 4ohm coils and I am using all stock from the shelf subs. I assume that is because AFAIK these are supposed to be in a sealed setup from per manufacture specs. His setup is approximately 2db louder but they sound identical according to the crowd :D
We used to get a lot of db gain on isobaric 3 chamber, all ported, 2 drivers. 30 years ago. I preferred conventional boxes for sound quality..these days if you put 2000 watts to a 10" maybe you won't miss the conventional feel?
Actually it's know that doubling power gains about 3 db on average. You can double the amount of speakers and get about the same 3db with that as well. Takes about 3 db for someone to notice a difference in "loudness"
@@davidmarles9409 show me a video where someone is doing 160+db where they simply double their power and gain 3db... do you ever attend serious audio competitions?
@@E4EonEbay I absolutely do and have gone to comps since the early 90's and you know as well as I do that's not what I meant. Once you have achieved the max power your speakers can take this obviously isn't true. Also there is way more to car audio spl than in a building where this holds much more true because a car obviously deflects and panel flex affects max spl....I know what I am talking about and this video wasn't referring to anything like you are saying. Also I listen to real music not test tones and most of us like an even volume through all the bass frequencies not just a specific frequency for spl. I prefer quality over loud.
he did this with equal size boxes the numbers wont change much or any if he removed the port. to get a bigger number from the ported box you would have to go bigger which is a whole different animal but for apples to apples this is a great video ..i have 9 15s i plan to use in a build and i want to go sealed just for the space savings all the subs inverted
I know most subs require a larger enclosure when going ported however according to the manual the optimal recommended enclosure size for both sealed or ported for these drivers is 2.5cf. Thanks for watching
Personally, I run subs in sealed boxes. I do not want them subs moving more than they were intended to. (I like hearing the artist that hit the bad drum with their foot... and know... that was a real person kicking a lever to hit a bad drum. Ported boxes loss the effects of reproductions of tfhe real thing. So... test the real stuff.... or the loud stuff... where do I go? The gain on ported doesnt matter to me.
In my concern, i prefer a sealed box, large as you can. Because i'm a dj and club's conceptor, i'm also a music lover. But a lot of peoples love the sound of ported enclosures. I don't discuss that, And build a lot of ported for them. So, my point is about the phase of the port.. You could'nt make a real waves with a mécanical off-phase output in this configuration.. I prefer compansate the roll off by more power and good equalisation, who let clean lower band make me smiling.
I think it depends on your preference I notice a ported box sounds very good in my Tahoe but in a car it sounds like a lot of rattling but sealed boxes sounds good in my car and Tahoe just not as much bass outside so I feel it depends on the vehicle and enclosed trunk or not and a open space trunk I feel ported sounds better in trucks and seal sound better in cars
I feel like every young persons first setup, “including myself” had a somewhat old school system. Gotta appreciate the old equipment. If a girl came up to me and said she was doing 145+ with some punches I woulda called BS 😂
Tuning with a port gains dB at the tuning frequency. The port tune should be at the most efficient frequency for the speaker box design for just boom or after roll off to gain bass extention in a flat out put design
I just turned 46 this week and I have a 22 year old daughter named Brianna and I installed her system myself like I have done for my trucks for the last 30 years.
That's awesome man! We gotta keep our children involved in the hobby of car audio so the passion can carry on to future generations. Thanks for watching and commenting!
great vid!! 20x25x12 = 6000 inch cube. = 3.47 feet cube.... thats a better box... sealed v. ported same = RF MARKETING PLOY....but i love your old skool approach!!your lucky you daughter enjoys your hobby!!my 3 kids heard bass when they were still in thier mom!! mom was a basshead...all 3 kids love bass!!but...some kids dont, and get headaches!!
Don't know how this popped up in my youtube sidebar but good video Steve. Hopefully we have shows again next year and I can see you and the family around the scene. As always if there's anything I have that would help you guys I'd let you borrow whatever.
Right, but with a ported box the bass travels farther and a closed box people will hear the bass hit harder closer to you. A ported box people will hear the bass farther away from you because it travels
1st, if that vehicle is in 50mph front end collision, that box is going to hit the back of your daughter's head at 50mph. That red strap around the PVC is not going to hold it in place. 2nd, your sealed volume is larger than your ported volume because the ports are now part of your volume. 3rd, ported should always be louder then sealed at the resonant frequency. A ported box is optimized for a specific frequency at the expense of others.
You are correct in that there will be roughly 100 cubic inches for a cylinder 4x8 or 0.058 cubic feet added to the sealed volume per side so 2.558 cf sealed vs 2.5 cf ported would technically be more accurate. However I honestly don't feel that 0.058cf (less than 1% , 0.232% to be exact) difference in enclosure volume would have altered the outcome enough to mention. Thanks for watching and commenting! (PS, her rear seatbacks fold and lock upright and she drives with rear seat belts latched in an X. The strap so it doesn't move left or right under normal driving, if seatbelts can hold back two 200lbs people I'm sure they will hold the box from coming through the rear seats...)
@@E4EonEbay Fair enough, your math checks out. I stand corrected. Regarding the speaker box, though, I am genuinely concerned. A 60mph head on collision (say, someone texting crosses the median) can generate enormous forces. It's not uncommon for 50 to 100 Gs to develop. Would your straps wrapped around that PVC pipe hold up a box weight 5,000 or 10,000 pounds or more? Maybe, but I would sleep better with the straps running through a few eye bolts on the sides 😉.
3 dB is the theoretical max at the tuning frequency of the port where the back and front waves are perfectly in phase. Obviously people expecting 3 dB across the spectrum will be disappointed! But ported is still a good bet when well tuned. Even for SQ, with a blindfold and optimal tuning, and especially in a car, almost no one could tell the difference (except the ported would be louder and therefore better).
My boy got a single rockford old school 15 the same one in a a sealed box i looked at it and expected it to sound like a kicker... and man that things got the best sound quality ive ever heard .. better than my jl w6 v3 sealed... And that thing gets loud on low watts i might buy it from him before he blows it
I know this is an old video and also not your goal, but it would be really cool to see a real world frequency response curve on ported vs sealed on this setup
Excursion wise yes, you can see the difference here - ruclips.net/video/gMjPjDh4bK4/видео.html but not on the meter I think it would drastically lower the score. Thanks for watching and commenting!
Thanks for watching and commenting! I should do a video using the meter to illustrate the gains from doubling power, I would want to clamp the amps or use an SMD Amm1 to show a power read out to confirm the power is doubled, would make a cool video.
I’ve been lookin all over but I’m trying to see if anybody has ran both sealed and ported boxes at the same time ? .. I’ve done it before in my mustang ... ported 12s in the trunk facing tag .. and the sealed box was right behind it facing the cabin poking out through the back seat! It made my windshield flex ! I was using a 2400 watt mono block Lanzer
Are the 36hz the tuning frequency? Then it should be way more than like 1,5db. If so, your ports are too small and compress very hard what makes them behave like a closed box on high spl due to much port speed.

What I've noticed is that, to gain 3db or more from the subs in a ported enclosure. You need an enclosure that's ridiculously large. As in like 2x larger.
I prefer sealed honestly. My 12s are in a sealed enclosure.
Small sealed box for cars, large ported box for home theater 👍
Yes, they're usually 2x as large😂
This agrees with the iron law that of course more space makes more Bass.
I've always loved triple or quadruple sealed setups because you can fit twice the drivers in the same amount of air space while maintaining a tighter more accurate sound that has more impact.
I'm actually headed out to the garage right now to start building my sealed enclosure for three 12-in stereo integrity SQL 12s. They are the best deal out there by a mile if you want ultra high performance xbl2 motor sealed subwoofer setups.
Ported can move a lot of air sure but you're never going to get that blur your eyeballs Hammer to the chest at a concert perfect drums feeling out of them.
sealed sounds better and hits lower. if you're going for spl then yeah ported. but i'm into SQ these days.
@@XX-121 if you run enough power on sealed it's still loud but has that concentrated impact and clarity and transient ability that ported doesn't it's worth running twice the power to a sealed setup
That's what I was hitting sealed back in 90's. Soundstream..
Old school yeahhh brings back memories
I ran that setup for the majority of my rookie season with NADBL, those oldschool subs helped carry me to an undefeated rookie season. Thanks for watching and commenting.
I actually felt my sealed box hits harder than my recently installed ported box. But mainly I see the gains going to a ported enclosure is air cooling and venting the heat out of the woofer which will give you more life out of your electronics! I’ll never buy a sealed box ever again
Nice video reminds me of back in 1998 when I was running 4 punch power DVC 15 with 2 punch power 1000s in a 1987 merkur xr4ti competing in spl competition as a privateer going up against all the car audio shops good stuff man
I have had so many systems but easily my favorite was back when I had a pair of Fosgate DVC 12's in a sealed box running off a MTX Black Gold amp. I just haven't been able to find a sub with the same force factor. I went to 4 12" JL audio 12w3 running off twice the power. It was loud but nothing even close to the beating the 2 Fosgate DVC 12's would give you. I wish Rockford Fosgate would release a classic series of car audio where the legends that made the company would be available. I would buy multiple systems just to have backups of everything.
Dad like me.. I also build stereos in the kids cars. Old school Rockford Fosgate too!! Thank you!!
But what sounds better? I had a sealed box with two Rockford Fosgate punch 12s and a 700watt Rockford amp and it was some of the tightest and cleanest bass and would put out 144db without any stress.
It doesn't matter if u win by a dB or a mile, winning is winning!.. I am a ported box guy can u tell? Lol good video and congrats for the win!
Thanks for watching and commenting!
I got nostalgic watching this. Last time I saw 2 Punch Power DVC 15s I installed them in a navigator, custom box with mirrors inside using Aeroports pushed by an Orion HCCA 250. It was humping!
Humping?
I’m hoping my kids will love this also give us more to do together… I’m hitting 110 with just a random set up. None name brand system with Pioneer radio touchscreen
Very interesting. I would like to see the same experiment done with frequency range.
Those are some of the best amps ever made. Very nice!
Your daughter is cute and the fact that she liked audio is a major plus (dont take it the wrong way) lol
No offense taken, it's always nice to be able to share a hobby with your children

How old are you bro!!!!!!???? Rob??? Cause shes 15 i think she just turned it and your sick asfuck... If i was steve ill beat the shit out of ypu in fact if i knew where ypu was at id still beat the shit out of you... Dick face...
Yea you definitely shouldn't take it serious a guy saying someone is cute...not manly lol
This question might have been asked and answered already in the comment thread but..Would you say in a music listening scenario instead of a db scenario, the sealed gives a better ,tighter, accurate bass response and is worth the loss of 1 plus some change db?? Thanks if you feel like answering! 👍🙏
Since nobody answered I will I absolutely know that the flatter response and better transient response of sealed makes it far superior for me but then again I'm a 46 year old musician that's been a lot of time on a metronome.
Also the earthquake reproduction characteristic of sealed where it literally displaces a section of air in your vehicle that is heaven and a ported does not do this it just fans around a whole bunch of air from the port and sub. It never has that instant earthquake shock type impact to it and I like that.
Damn keepin or old school. I love olllld fosgate stuff
You've probably gone on to a different setup by now, but I wonder what your air speed is in those ports. They might be compressing your output. Also, porting increases the volume at a specific frequency, so it's not necessarily 'supposed' to be +3dB everywhere in the range. Your port tuning and your listening area's tuning are two very different things.
That's a great score for some legendary gear
Thanks man, it is stuff that was built to last for sure. Thanks for watching and commenting!
Radio will make a big difference as well. You could easily upgrade that jvc radio and gain more juice for your sounds.
She is running a Punch X crossover which gives a decent bump in RCA signal voltage. I run a Rockford PA1 preamp in my jeep and can get above 8v clean signal to my amps. Definitely makes a difference having strong signal and a lower noise floor. Thanks for watching and commenting!
Yup Pioneer FTW!
That’s a badass set-up all fosgate!
Thanks for Watching And Commenting!
Cool video man thanks! I remember your setup on EXO's channel and even remember thinking, it'd be cool to see numbers. Thanks again!
Your welcome, thanks for watching and commenting!
Thanks for your time on explaining the difference between sealed and ported. Good video
I'd like to see the dB reading at 20-25hz sealed vs ported. I'm interested to see which will hit harder on the low frequencies. Great video.
Thanks for watching and commenting. I'm assuming if the ported side were tuned low enough it could be quite interesting to see. I did do a video showing the excursion side by side playing 20hz - ruclips.net/video/gMjPjDh4bK4/видео.html
If the ported box is Tuned right. It vil be louder at Lower frequencies.
Sealed has almost flat response over Low frequencies. If you have a powerful amp and a subwoofer, go for sealed for hard hitting bass
That’s dedication to music right there!
She's quite the basshead, just started her own channel - ruclips.net/channel/UCTKrYsApDlmKB3v5tG7__3w?pbjreload=10 - She took 1st in Rookie at the Team Deadly Hertz show, you can see her meter run here - ruclips.net/video/2O4SeJzHci4/видео.html She is currently a 151.5, her latest competition was the Frozen SPL show - ruclips.net/video/ChR0gRUubCc/видео.html Thanks for watching and commenting! Please like & Subscribe!!!! - Meter used was an SSA APM1 Meter. The enclosure has separate chambers, 2.5cf each after displacements, with the port flares it is tuned to 35hz
Steve Young im running a prime 500 2ohm to a single p2 12 2 ohm in a p box single ported. It does good for 1.8 cf box but i want a lil more out of it ! Any help would be appreciated . Was thinkn bout goin to a p3 but i dont think the 500 prime can push it? Ty
Great video 👍 and congrats on her win. Definitely love old school equipment !!!!!
Thanks for watching and commenting! The oldschool equipment always brings back memories.
I’ve moved my boxes around my trunk just to see if the box is facing your back you get different thump or set up as close to the rear as you can speakers facing the rear.
Awesome video! Tuned in for the other tests specially the cone area test 1 15 vs 2 15s
Hopefully I can get one done soon, still crappy weather up this way, snow / rain mix last night. Thanks for watching and commenting!
I had a similar situation with my triple audiobahn alum10q's. Friend if mine has 3 as well. Mine are sealed and his is ported and we can not find any major differences between the outputs. The difference is that he rebuilt his with dual 4ohm coils and I am using all stock from the shelf subs. I assume that is because AFAIK these are supposed to be in a sealed setup from per manufacture specs. His setup is approximately 2db louder but they sound identical according to the crowd :D
First video I’ve watched of you and I really liked it. Sub!
We used to get a lot of db gain on isobaric 3 chamber, all ported, 2 drivers. 30 years ago. I preferred conventional boxes for sound quality..these days if you put 2000 watts to a 10" maybe you won't miss the conventional feel?
to gain 1 db you have to double sound level, so its a huge gain. db works in a logaritmic scale not in a linear one
Actually it's know that doubling power gains about 3 db on average. You can double the amount of speakers and get about the same 3db with that as well. Takes about 3 db for someone to notice a difference in "loudness"
@@davidmarles9409 that therory always sounds good on paper, and may work at lower db levels but that idea goes out the window at high SPL levels.
@@E4EonEbay I'm sorry I have to disagree. There are plenty of videos that prove this is very accurate.
@@davidmarles9409 show me a video where someone is doing 160+db where they simply double their power and gain 3db... do you ever attend serious audio competitions?
@@E4EonEbay I absolutely do and have gone to comps since the early 90's and you know as well as I do that's not what I meant. Once you have achieved the max power your speakers can take this obviously isn't true. Also there is way more to car audio spl than in a building where this holds much more true because a car obviously deflects and panel flex affects max spl....I know what I am talking about and this video wasn't referring to anything like you are saying. Also I listen to real music not test tones and most of us like an even volume through all the bass frequencies not just a specific frequency for spl. I prefer quality over loud.
he did this with equal size boxes the numbers wont change much or any if he removed the port. to get a bigger number from the ported box you would have to go bigger which is a whole different animal but for apples to apples this is a great video ..i have 9 15s i plan to use in a build and i want to go sealed just for the space savings all the subs inverted
I know most subs require a larger enclosure when going ported however according to the manual the optimal recommended enclosure size for both sealed or ported for these drivers is 2.5cf. Thanks for watching
Personally, I run subs in sealed boxes. I do not want them subs moving more than they were intended to. (I like hearing the artist that hit the bad drum with their foot... and know... that was a real person kicking a lever to hit a bad drum. Ported boxes loss the effects of reproductions of tfhe real thing. So... test the real stuff.... or the loud stuff... where do I go? The gain on ported doesnt matter to me.
In my concern, i prefer a sealed box, large as you can. Because i'm a dj and club's conceptor, i'm also a music lover.
But a lot of peoples love the sound of ported enclosures. I don't discuss that, And build a lot of ported for them.
So, my point is about the phase of the port.. You could'nt make a real waves with a mécanical off-phase output in this configuration.. I prefer compansate the roll off by more power and good equalisation, who let clean lower band make me smiling.
So ported subwoofers are monsters I like your practical
Old setup forsure if it ain’t broke don’t fix it ; ) I always replaced my subs when I blew them up havnt gotten to use my w710 as much as I’d like to
It's amazing the durability of the USA made oldschool equipment. Thanks for watching and commenting!
I think it depends on your preference I notice a ported box sounds very good in my Tahoe but in a car it sounds like a lot of rattling but sealed boxes sounds good in my car and Tahoe just not as much bass outside so I feel it depends on the vehicle and enclosed trunk or not and a open space trunk I feel ported sounds better in trucks and seal sound better in cars
I feel like every young persons first setup, “including myself” had a somewhat old school system. Gotta appreciate the old equipment. If a girl came up to me and said she was doing 145+ with some punches I woulda called BS 😂
Its amazing to think they can still hang with some of the modern equipment out there. Thanks for watching and commenting!
This is where it started. They is A lot of technology out there but things have the same concept.
Great vid as usual Steve. Interesting to say the least
Steve B. Thanks for watching!
Tuning with a port gains dB at the tuning frequency. The port tune should be at the most efficient frequency for the speaker box design for just boom or after roll off to gain bass extention in a flat out put design
I just turned 46 this week and I have a 22 year old daughter named Brianna and I installed her system myself like I have done for my trucks for the last 30 years.
That's awesome man! We gotta keep our children involved in the hobby of car audio so the passion can carry on to future generations. Thanks for watching and commenting!
Steve Young agreed 💯%.
great vid!! 20x25x12 = 6000 inch cube. = 3.47 feet cube.... thats a better box... sealed v. ported same = RF MARKETING PLOY....but i love your old skool approach!!your lucky you daughter enjoys your hobby!!my 3 kids heard bass when they were still in thier mom!! mom was a basshead...all 3 kids love bass!!but...some kids dont, and get headaches!!
Love those old school fosgates
I miss those old amps so much 😢😢
I got one of those amps a 750w pushing to JL 12's in my wife's mbz. ....

Love that box. Saw it on EXO's channel.
Yeah, it is very recognizable for sure, it's a fun box to play with. Thanks for watching and commenting!
@@E4EonEbay keep up the great work Steve. Not only can you build a bad ass box but you were a half descent Quarterback as well 😉! LoL
Great video ! cool to see a fellow member of Legends of Car Audio.
Think long and hard fellas... when was the last time you heard someone pull up beside you bumpin, and it's a female? She's a diamond in the rough.
Don't know how this popped up in my youtube sidebar but good video Steve. Hopefully we have shows again next year and I can see you and the family around the scene. As always if there's anything I have that would help you guys I'd let you borrow whatever.
Right, but with a ported box the bass travels farther and a closed box people will hear the bass hit harder closer to you. A ported box people will hear the bass farther away from you because it travels
1st, if that vehicle is in 50mph front end collision, that box is going to hit the back of your daughter's head at 50mph. That red strap around the PVC is not going to hold it in place.
2nd, your sealed volume is larger than your ported volume because the ports are now part of your volume.
3rd, ported should always be louder then sealed at the resonant frequency. A ported box is optimized for a specific frequency at the expense of others.
You are correct in that there will be roughly 100 cubic inches for a cylinder 4x8 or 0.058 cubic feet added to the sealed volume per side so 2.558 cf sealed vs 2.5 cf ported would technically be more accurate. However I honestly don't feel that 0.058cf (less than 1% , 0.232% to be exact) difference in enclosure volume would have altered the outcome enough to mention. Thanks for watching and commenting! (PS, her rear seatbacks fold and lock upright and she drives with rear seat belts latched in an X. The strap so it doesn't move left or right under normal driving, if seatbelts can hold back two 200lbs people I'm sure they will hold the box from coming through the rear seats...)
@@E4EonEbay Fair enough, your math checks out. I stand corrected.
Regarding the speaker box, though, I am genuinely concerned. A 60mph head on collision (say, someone texting crosses the median) can generate enormous forces. It's not uncommon for 50 to 100 Gs to develop. Would your straps wrapped around that PVC pipe hold up a box weight 5,000 or 10,000 pounds or more? Maybe, but I would sleep better with the straps running through a few eye bolts on the sides 😉.
Beautiful comparison
Thanks for watching and commenting!
Awesome Dad.
3 dB is the theoretical max at the tuning frequency of the port where the back and front waves are perfectly in phase. Obviously people expecting 3 dB across the spectrum will be disappointed! But ported is still a good bet when well tuned. Even for SQ, with a blindfold and optimal tuning, and especially in a car, almost no one could tell the difference (except the ported would be louder and therefore better).
Great example. Can you measure the difference of facing the woofers forward vs backwards and upwards?
My boy got a single rockford old school 15 the same one in a a sealed box i looked at it and expected it to sound like a kicker... and man that things got the best sound quality ive ever heard .. better than my jl w6 v3 sealed... And that thing gets loud on low watts i might buy it from him before he blows it
Hey thank you for the information appreciated... however in the vehicle can you feel a significant difference ?
Thanks for this video.. I have a sealed box that I haven’t used since I bought it.. I’m not trying to hit SPL level.. just I nice tight bass
I know this is an old video and also not your goal, but it would be really cool to see a real world frequency response curve on ported vs sealed on this setup
Me too, unfortunately the box has been retired, perhaps I will build another and do some more experiments
Have you tried to keep one plug in to see what kinda change that would make
Excursion wise yes, you can see the difference here - ruclips.net/video/gMjPjDh4bK4/видео.html but not on the meter I think it would drastically lower the score. Thanks for watching and commenting!
These were some of the top speakers back in the Day, and Kickers not so good at that time
Old school Fosgate for the win!
I use to have these babys in 12s old school nice
Mate. Every 3 DB gain is double the Power. To get 1.5 DB gain is great stuff and half power more for free
Thanks for watching and commenting! I should do a video using the meter to illustrate the gains from doubling power, I would want to clamp the amps or use an SMD Amm1 to show a power read out to confirm the power is doubled, would make a cool video.
Easy man easy on Dem ol subs
@@fuckgoogleandyou8779 they can take it 💪
appculture I thought it was double every 10db.
I’ve been lookin all over but I’m trying to see if anybody has ran both sealed and ported boxes at the same time ? .. I’ve done it before in my mustang ... ported 12s in the trunk facing tag .. and the sealed box was right behind it facing the cabin poking out through the back seat! It made my windshield flex ! I was using a 2400 watt mono block Lanzer
What about inverted subs? Wgats the difference?
Damnnnnnnn that's tight. Love the old school stuff

maybe we can fix on 96
Thats his daughter. Have some respect lol
@@ArnoldGaming people are pigs 🐖 🙄
I can hear the bass response difference in the video. The sealed was a cleaner tone and the port open was like a hum.
I had those subs they bang.lot of power for them.i still have a power 1000 from that series.next yr model after the 1100
Nice job on the test video and on winning 1st place
Are the 36hz the tuning frequency? Then it should be way more than like 1,5db. If so, your ports are too small and compress very hard what makes them behave like a closed box on high spl due to much port speed.
Nice convertible 3 series!
