I hope these "ported" enclosures are not one size fit all.

^^ I'm very insulted.

uncald4 - have you ever measured the corner loading by using one of these boxes? I have one, I might guess it on the order of 3-6dbs (anecdotally) at the dash but I don't care enough to remove the sub, uninstall the box, move the box up near the rear seats and test.

Anyway, just curious.

We did all the R&D on this design and location years ago. In 2005 I think using an RTA. We used a (new at the time) Civic Si, a VW Jetta, an Accord and a new TL. They all produced better results with the subwoofer off to the side. However, placing the subwoofer closer to the seat provided a minimal gain. It also took up a lot more space in the trunk.

NOTE...

Every box that we build for you is tailored to the subwoofer that you plan to use. The correct airspace, the correct cutout and the correct mounting plate specs are used. In ported boxes we use the correct port displacement and tuning specs. This is the right way to build it. It's the only way we build it. Holler.

Not to bust ur balls, but what is the "correct" tuning specs?

low? high?

Don't be

You make nice boxes.

Well respected and appreciate you asking the questions for potential buyers, another product that if I didn't already have something, I'd consider.

^ me too

If anybody cares, my corner box is 5.1db louder than the same sub in the same box up against the seat point forwards or backwards at 40hz. I finally got unlazy and tested it out...

stevemk07

In my testing i also found to the side was louder. I have it in the middle though to minimize n vibrations through the frame

Trunk Monkey

iTrader: (1)

Wow! Really!?? Any perceived sound change? SQ changes, etc? I forgot what you're running again...FI q on 1,000 or something right?


...it's not loud enough then!

Last time you will ever see uncald4 on AZ....

January 31st 2012.

You guys can still email and FB me but I won't be here on the forum.

stevemk07

Having said that I am interested in this box. Only thing that troubles me is whether I should i get a 10" or 12" sealed.

uncald4

iTrader: (3)

They both produce a good amount of bass but go with what you know. Everyone has their own opinion. I prefer 8" and 10" subs.

Whichever you choose I'll make it look good and sound awesome.

You gone as a vendor, or as a forum member?!?!

Why? If you don't mind me asking.

TmaX

iTrader: (1)

Probably as a vendor but for clarity sake he won't take order's via PM.
Instead we can email/facebook him to place orders.

Id assume the promo price would still be valid though.

For the love of god there's no sound difference in the sub frequencies based on cone area

niebur3

^^^Thanks for that post!

I hate cars

Lol. You can say that every day and someone will still say the opposite every day. Just look at the "which sub size do you prefer" thread on DIYMA. I corrected every person that said 8s for rock, 10s for country, 12s for techno and a little bit of everthing, and 15s for rap or something to that effect. I did it for my own amusement and every time I clicked on that thread there was a new similar post. That myth won't go away anytime soon.

I do like large subs for the efficiency and less excursion required along with a generally lower Fs, but the tight or punchy or sloppy or whatever sound is determined mostly by the enclosure.

rockstar143

iTrader: (6)

That's good to know...I actually didn't. I thought smaller gave punchier, tighter bass.

My dream setup is probably that 1 or 2 IB setup you go goin on. I wish my 12" Audiobahn's could run IB.

Trunk Monkey

iTrader: (1)

Are the specs just that bad for IB or what?? Why not try them out and if they don't work.... I see an excuse for new subs!

I hate cars

That's what I was wondering, what model are they, I want to see how they spec out. The flame ones look an awful lot like Pyle subs which actually work well in IB.

iTrader: (2)

Me too. I thought I had to get a 10 since I preferred techno. I may just a 12 now if this is the case.

I hate cars

Always go with the most cone area you can fit in the proper enclosure. However, putting a large sub or any other sub in too small of an enclosure will make it sound boomy. Or said another way, if you can't give it the airspace it needs, go with a smaller sub. Most facory recommended enclosure sizes are on the small side to make it harder to damage the subs. Most will sound better in larger enclosures. Using my trunk as the enclosure, my 15s produce incredibly powerful, tight, quick bass.

^ prove it. Call me when you get to Oklahoma City lol. Ahh...I wanna hear IB!! That FISH guy from DIYMA has the AE IB15's along with a bunch of other stuff...maybe I'll go have a listen.

I'm leaving as a vendor but that also kills my username.

I used to do a ton of business here on AZ which was well worth the vendor fee. But now everyone here is a professional. Everyone knows what I know and can do what I do. It's very discouraging and makes it impossible to do business.

You guys can do me a favor and LIKE us on Facebook. Check out the work we do in-shop.

I'll take orders via PM. I just recommend email or FB because I get instant notifications and can respond much faster versus a PM.

Smaller subwoofers move faster. The size of the cone and motor structure definitely plays into the dynamics of a bass note. Those characteristics also play into how a bass note matures in the given space of a vehicle. A bigger subwoofer doesn't necessarily equate to bigger bass.

Wow... the audio committee trashed my thread.

VicTL06

Sorry to see you leave, but business is business. I liked your page and I'm hoping to flip you an email (can't do it from the office) about my needs and setting something up for later in the year for me to drive down and have an install. Is your sale still going on until February 22nd or has it been truncated to January 31st?

I hate cars

This shows why you get defensive and/or crack smart ass jokes everytime anyone asks a simple legit question about your product like airspace. I've kept quiet because I've never had the intention of buying one of your products but you can't talk down to people and then make such a ridiculous statement.

I'll promise you my 15s will keep up with any 8" sub out there in "quickness".

How can one sub be "quicker" than another? If it's playing a 30hz tone, it's moving in and out 30 times a second. This is true whether it's an 8" or a 15" sub. If it's moving slower or faster, it's playing a different frequency. With higher moving mass comes more motor strength to offset the difference. Or with a 15 like mine, moving mass is lower than many 10s.

If you're talking transient response, that's related to frequency response. The enclosure determines much of that. A small enclosure will make a sub sound "slower" and boomy regardless of the sub's size. Many people want a 15 but don't have the room so they stuff it in an enclosoure that's too small for the sub and then complain that 15s are slow. You could argue that a large sub does not have to move as far for a given SPL so it could have even quicker response though that's not true.

Larger will have less excursion for the same SPL resulting in less distortion. Larger will have higher efficiency resulting in a lower power requirement. Larger will have a lower Fs resulting in more effortless and more efficient low bass. Larger usually has more xmax for even more output.

A bigger sub in the same location, in the equivalent enclosure off of the same power, all else being equal will always result in more bass and it will likely sound better as well. 8s have one advantage... space.

Anyone in Ca that wants to hear my "slow" 15s is more than welcome to take a listen to prove this theory wrong once and for all. These myths need to die.

Sweet, thank you! The discount will carry until Feb 22nd.

Whoa now!

A 15" subwoofer and an 8" subwoofer both make a 30hz tone, that's correct. At 30hz they are both moving "at the same speed". Let's relate this to something similar. Both a Ford F-150 and Lamborghini Aventador can do 60mph. At 60mph they are both going the exact same speed. Would you argue that the Ford pickup is just as fast?

I would argue that the Lambo can get up to speed much faster and slow down/stop way faster. It takes a subwoofer of larger mass more time to react to changes in AC current. It takes a smaller sub less time to do the same.

Not trashing your thread at all. Hell I can't build a fiberglass enclosure like that so I'd come to you if I needed one. I've told many people about your enclosures and I'm pretty sure multiple people have gotten them. Not talking down on what you do or questioning what you do. My comment was in regard to "whether I should get a 10" or 12" question....


I would think that your statement would have to do with moving mass and motor strength. I dunno though...

I hate cars

I'm not arguing theory, this is well discussed and proven by some of the top guys in the industry. Do a search on DIYMA and you'll find some big names, some of which design some of the popular subs around here tell you the same. Not to mention I happen to have a pair of 15s in the trunk and I've heard many 8" and 10" subs and they have nothing on the 15s in "quickness". I've also used the 15s up to 2,200hz when I was waiting on other speakers to arrive. They play plenty high when needed.

If a 15" sub is moving 5mm on a 60hz tone and an 8" is moving 5mm on a 60hz tone, they're both accelerating at the exact same rate. They're starting and stopping 5 times per second and covering the same 5mm distance in between starts and stops. How can one be accelerating quicker than the other?

You're talking about an electrical motor here. One reacts just as quick as the next. Motor strength controls the cone so if you have a heavier cone, you add motor strength.

When talking about a small sealed box, the airspring does more to resist the movement of the cone than the mass of the cone.

Think about why in every sub line, as you go up in size, efficiency goes up as well.

There is absolutely no connection between sub size and quickness.
