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.
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.

It’s awesome that you gave that system to your daughter and encourage car audio. All I ever heard from my parents My parents was “Waste of money” and “Turn that shit down” lol
Thats not on a Term Lab= new style pressure sensor type SPL meter. I had a walled 2-15" Power Hx2 Rockfords, with 2-Bd 1500s strapped, & I hit a 164Db on the old style SPL meter back then. When i ✔ it later on, with a New Term Lab meter, it only did a 149.9Db to my surprise= the new meter showed over 14 Db Less👀, everything was the same, metering positioning, subs, enclosure, amps, wiring, batteries(6 Qty.) & 1 alternator. Now to be fair, the old Audio Control meters could be manipulated by +, or - 10 Db with a knob. But even when calibrated properly, these old SPL meters lost there calibration very quickly, making them very inconsistent @ best. Not to mention that + or - 10 Db knob that i have seen used to cheat scores during a competition to make a fellow friend or competitor score "Louder", then turn the knob back down, to be able to win! These new Term Lab meters can NOT be manipulated/changed, to prevent cheating. Sorry if this hurts your feelings, but your 157.5 Db score would probably be about a 143Db to 145Db on the Term Lab SPL meter, which was not used in 2001 yet.
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 :)
All three of my kids are into audio, its a great feeling, if we don't pass out hobbies and interests on to our kids they will fade. Thanks for watching and commenting!
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.
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
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!
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!

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.
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’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
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. I honestly don't feel that 0.058cf (0.232% difference to be exact) in volume would have altered the outcome enough to mention. Thanks for watching and commenting!
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 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.
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’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 noticed the passenger climate display light has went out mine went out to was wondering if it was from beating on the dash to eject CDs from Factory CD player
does the 4" x 14" port mean 4" diameter tube cut to 14" length? I thought it meant a rectangle cutout 4" high and 14" wide. I think it needs a larger port than the 4" diameter. Which is correct?
Wanting to know more about your setup. I got the same DVC 15s sealed but trying to still find RF amps to match. Are you running at 1ohm or 2ohm. Any upgrades to charging system so on.tia
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.
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.
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.
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
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).
What do you expect it to look lie? Look at the wiring you can see. It's awful, and borderline dangerous. I wouldn't let my daughter drive a half-a$$ed system like that. You can save money, but still install thing with pride. This system is as sloppy as I've seen.
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
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
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!
notes are slightly more boomy, but depending on how the box is designed a ported enclosure can sound better than a sealed in my opinion. 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
Can the old school fosgate 2 channel amps like 700s, 800.2 and the 4 channel power 400.4 be bridged and each channel ran at 2 ohms? I chatted with Rockford fosgate, and they said no, 4 ohm minimum per channel on those amps bridged. Thanks
Rockford technicians are not gonna tell u what those amps are really capable of. The are stable at 2 ohm. U can even run them at 1 ohm but they are not stable. Will heat up real quick and u will burn it up if ur not capable. I run mines at 2 ohm all day long and have never had a problem
I have ran my power 1100a2 amps at 2 ohms mono all day long, if fed properly, keeping your voltage high and stable they don't heat up too much. I have even ran them in short bursts at 1 ohm mono for competitions and they have held up and not died on me.
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
Class D amps are fine for bass in my opinion, however I do not feel they are suitable for mids and highs if you are using quality set of component speakers and looking for the best sound quality. I'm sure the majority of people wouldn't notice but for those still listening to cd's instead of bluetooth from youtube they would notice. Thanks for watching and commenting!
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
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.

It’s awesome that you gave that system to your daughter and encourage car audio. All I ever heard from my parents My parents was “Waste of money” and “Turn that shit down” lol
You got audiophiles and pedophiles. ...lol
I hit a 157.5 at an SPL comp back in 2001 running 3 JL 12’s and a punch 800A2
Thats not on a Term Lab= new style pressure sensor type SPL meter. I had a walled 2-15" Power Hx2 Rockfords, with 2-Bd 1500s strapped, & I hit a 164Db on the old style SPL meter back then. When i ✔ it later on, with a New Term Lab meter, it only did a 149.9Db to my surprise= the new meter showed over 14 Db Less👀, everything was the same, metering positioning, subs, enclosure, amps, wiring, batteries(6 Qty.) & 1 alternator. Now to be fair, the old Audio Control meters could be manipulated by +, or - 10 Db with a knob. But even when calibrated properly, these old SPL meters lost there calibration very quickly, making them very inconsistent @ best. Not to mention that + or - 10 Db knob that i have seen used to cheat scores during a competition to make a fellow friend or competitor score "Louder", then turn the knob back down, to be able to win! These new Term Lab meters can NOT be manipulated/changed, to prevent cheating. Sorry if this hurts your feelings, but your 157.5 Db score would probably be about a 143Db to 145Db on the Term Lab SPL meter, which was not used in 2001 yet.
So was not expecting he 1st test. Had the sounds up and started the hell out of me
Those are some of the best amps ever made. Very nice!
Ported sounds better outside the vehicle. Sealed sounds better inside the vehicle.
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 :)
All three of my kids are into audio, its a great feeling, if we don't pass out hobbies and interests on to our kids they will fade. Thanks for watching and commenting!
You are so right, that's why I wanna have kids someday to enjoy loud bass with and keep the hobby going :)
Thanks for your time on explaining the difference between sealed and ported. Good video
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.
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
Dad like me.. I also build stereos in the kids cars. Old school Rockford Fosgate too!! Thank you!!
Very interesting. I would like to see the same experiment done with frequency range.
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!
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!
That’s a badass set-up all fosgate!
Thanks for Watching And Commenting!
i loved my old rockford subs like those.
They bring back memories for so many people. Thanks for watching and commenting!
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
@@davidlodiemyer5698 ahhahaha

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
Great video ! cool to see a fellow member of Legends of Car Audio.
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.
Sealed: 1:33
Ported 2:45
That’s dedication to music right there!
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’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
Did you account for the volume of the external ports when designing the box?
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. I honestly don't feel that 0.058cf (0.232% difference to be exact) in volume would have altered the outcome enough to mention. Thanks for watching and commenting!
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!
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 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.
Have you ever tested it when suspended in mid air?
Wtf? Lmao
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’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 noticed the passenger climate display light has went out mine went out to was wondering if it was from beating on the dash to eject CDs from Factory CD player
does the 4" x 14" port mean 4" diameter tube cut to 14" length?
I thought it meant a rectangle cutout 4" high and 14" wide.
I think it needs a larger port than the 4" diameter.
Which is correct?
Wanting to know more about your setup. I got the same DVC 15s sealed but trying to still find RF amps to match. Are you running at 1ohm or 2ohm. Any upgrades to charging system so on.tia
Nice job on the test video and on winning 1st place
I understand the loudness... But, how does the SOUND vary between sealed and ported with regular music?!! Does one hit harder than the other?
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.
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.
Great example. Can you measure the difference of facing the woofers forward vs backwards and upwards?
Which one sounds better musically?
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?
Hey thank you for the information appreciated... however in the vehicle can you feel a significant difference ?
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.
What about cabin pressure if u roll the windows down it might be a higher score
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
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!
Old school Fosgate for the win!
Great video 👍 and congrats on her win. Definitely love old school equipment !!!!!
Thanks for watching and commenting! The oldschool equipment always brings back memories.
Beautiful comparison
Thanks for watching and commenting!
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).
Can we get a quick view of battery, alternator, and any electric components I.E., caps
What do you expect it to look lie? Look at the wiring you can see. It's awful, and borderline dangerous. I wouldn't let my daughter drive a half-a$$ed system like that. You can save money, but still install thing with pride. This system is as sloppy as I've seen.
So ported subwoofers are monsters I like your practical
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!
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
I have a single can f250. Should I get a a 10 inch sub on 1000 watts rms, or 3 6.5”s on 400 watt rms each???
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
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?
Does the bass feel "smoother" when sealed and more "boomy" when ported? Or is that difference also negligible?
notes are slightly more boomy, but depending on how the box is designed a ported enclosure can sound better than a sealed in my opinion. Thanks for watching and commenting.
Mine is a huge difference sealed vs ported. For sealed I would need a bigger amp.
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
What head unit is that..I have an Isuzu ascender Wich is the same as the trailblazer and I'm looking for a head unit that is a double din..
the_professional18 JVC KW-V230BT
Is there a difference between being in a car trunk or being an SUV or is it all the same
Would 30hz be the same? About a 1db difference?
These were some of the top speakers back in the Day, and Kickers not so good at that time
I can hear the bass response difference in the video. The sealed was a cleaner tone and the port open was like a hum.
Can the old school fosgate 2 channel amps like 700s, 800.2 and the 4 channel power 400.4 be bridged and each channel ran at 2 ohms? I chatted with Rockford fosgate, and they said no, 4 ohm minimum per channel on those amps bridged. Thanks
Rockford technicians are not gonna tell u what those amps are really capable of. The are stable at 2 ohm. U can even run them at 1 ohm but they are not stable. Will heat up real quick and u will burn it up if ur not capable. I run mines at 2 ohm all day long and have never had a problem
I have ran my power 1100a2 amps at 2 ohms mono all day long, if fed properly, keeping your voltage high and stable they don't heat up too much. I have even ran them in short bursts at 1 ohm mono for competitions and they have held up and not died on me.
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
what do you think of class d amps, so tiny, more than 90% efficient, very less heat, excellent freq. response.
Class D amps are fine for bass in my opinion, however I do not feel they are suitable for mids and highs if you are using quality set of component speakers and looking for the best sound quality. I'm sure the majority of people wouldn't notice but for those still listening to cd's instead of bluetooth from youtube they would notice. Thanks for watching and commenting!
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
Those old punch subs are awesome
Great vid as usual Steve. Interesting to say the least
Steve B. Thanks for watching!
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
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.
Love those old school fosgates
Appreciate the knowledge learned some today
Hey man how’s the difference of sound quality thoigh
When you cap off the ports are you including the port size in the total space for a sealed enclosure? Just curious
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.
