[@quintonnkoane9885]

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.

[@vikassm]

Small sealed box for cars, large ported box for home theater 👍 Yes, they're usually 2x as large😂

[@johnnycorn7225]

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.

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.

[@Kcducttaper1]

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.

[@azcheron]

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.

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! 👍🙏

[@johnnycorn7225]

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.

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.

[@YipperX5]

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

[@phreaktor]

Did you account for the volume of the external ports when designing the box?

[@E4EonEbay]

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.

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

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 can hear the bass response difference in the video. The sealed was a cleaner tone and the port open was like a hum.

[@kenhaze5230]

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).

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!

[@turntup3250]

Awesome video! Tuned in for the other tests specially the cone area test 1 15 vs 2 15s

[@E4EonEbay]

Hopefully I can get one done soon, still crappy weather up this way, snow / rain mix last night. Thanks for watching and commenting!

[@andrewdenine1685]

Mine is a huge difference sealed vs ported. For sealed I would need a bigger amp.

[@onesikm3]

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

[@CLIFFWILKES]

Hey thank you for the information appreciated... however in the vehicle can you feel a significant difference ?

[@mjl6425]

Nice comparison but I wonder how much of a difference there would be sealed if you just took the ports out instead of plugging them?

[@skymiller7035]

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

[@todddooley793]

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!

[@E4EonEbay]

Your welcome, thanks for watching and commenting!

[@juliuswashington9734]

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

[@nuclearbum9858]

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

[@E4EonEbay]

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

[@Newschoolcovers]

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.

[@hoseahanslip9190]

I understand the loudness... But, how does the SOUND vary between sealed and ported with regular music?!! Does one hit harder than the other?

[@garrettgiuffre7298]

Man I want the bass I didn't hear I really only felt it then noticed it from the windows of this Tahoe looking like Jello. I want this but I don't want to love all my space and shovel out tons of cash. Is it possible to get that from small and affordable?

[@RudyM2024]

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!

[@E4EonEbay]

Thanks for watching and commenting!

[@RudyM2024]

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!

[@goodstuffohhyeah]

Humping?

[@pureonyx5090]

Great video 👍 and congrats on her win. Definitely love old school equipment !!!!!

[@E4EonEbay]

Thanks for watching and commenting! The oldschool equipment always brings back memories.

[@AllaboutTheWoodrows]

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

[@E4EonEbay]

It's amazing the durability of the USA made oldschool equipment. Thanks for watching and commenting!

[@zumazoomzoom7632]

The tone changes with the port vs sealed. One better for punchy bass one for longer harder bass

[@salscrofano7870]

It definitely does make a difference, I had a scar ddx 12 in a sealed box and just switched to scar’s ported box and there’s a big difference, it sounds way better and has better low range bass

[@iseeyou9078]

Completely different parameters for the scar DDX.

[@tylerbusch9999]

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 😂

[@E4EonEbay]

Its amazing to think they can still hang with some of the modern equipment out there. Thanks for watching and commenting!

[@anthonyabner5753]

This is where it started. They is A lot of technology out there but things have the same concept.

[@scottychadwick9580]

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

[@slippyg]

Have you ever tested it when suspended in mid air?

[@christianparks5343]

Wtf? Lmao

[@alchemyhendricks725]

Old school Fosgate for the win!

[@malvizar85]

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

[@txroaddogg1709]

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

[@E4EonEbay]

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.

[@jermainephillips5179]

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

[@zglphillips-panui7624]

Gotta seal one and port the other, i think you would cover more bass frequencies

[@SaGeMitis]

Blocking off the ports makes it bigger when sealed bc the ported volume doesn't include port displacement and when you seal it off the ports become part of the sealed enclosure, thus making the sealed more like 2.55ish

[@E4EonEbay]

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. I honestly don't feel that 0.058cf (less than 1% , 0.232% to be exact) difference in volume would have altered the outcome enough to mention. Thanks for watching and commenting!

[@SaGeMitis]

@@E4EonEbay thanks for taking the time to show the difference tho👍

[@E4EonEbay]

@@SaGeMitis no worries, it's a fun box to play with, it's no longer in her car. She is running 2 sundown zv3 15s on a Team Cactus 5k at the moment. I still have the Rockfords and the box though. The interesting videos on my channel is the one where I play 20hz sealed vs ported side by side.

[@coltonnewman8283]

I watched this video because I recognized the subs and box on the thumbnail

[@E4EonEbay]

It's a pretty recognizable enclosure no doubt, EXO made it well known for sure! Thanks for watching and commenting!

[@pballer2005]

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

[@E4EonEbay]

Me too, unfortunately the box has been retired, perhaps I will build another and do some more experiments

[@eros40oz211]

Can we get a quick view of battery, alternator, and any electric components I.E., caps

[@thehifiwifiguy]

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.
