"not sure yet... frames usually take 3mos, well 2mos min, 30days to make, 30 days on the water"

He said he might air ship some more in but he wasnt positive about that, so judging by what I heard from John directly, it can take 5 months before you see your subs if you ordered today....

If it wasnt for such the long wait I would have certainly gone with AE IB15's

The AV15 geared for large box would be really nice to if you want to use two. They would model very well in a car trunk. The only reason I'm not doing that right now is to save weight and because I really don't need the extra output.

I had a double 3/4 MDF baffle but I got lazy and didn't use metal L-pads with screws in the chassis for the top, just expanding foam. It ripped immediately and then the baffle flexed to death.

Thats a nice idea, wish I had access to a welder and knew how to use it. But even when I had my 2 IDMAX's with double 3/4" MDF baffle I never had any trouble with it vibrating and flexing, at least that I could tell.

Are you saying that with the AE, I can break the 3x Vas rule? I have a vw cabrio with a 7.6 cubic ft. trunk...that is beggin for this sub if that is the case. Do you think that it would work?

^ Model your trunk as a sealed enclosure. None of us can get true IB in a car and these subs are not true IB subs, they are basically large sealed drivers.

You trunk is good for one IB15, or two AV15, or 4 IB12. Also keep track of what you put in your trunk, it will increase your Q! Just noticed you have a softop too. Check our my newest thread on the S2000. See if you have a rear deck like mine, it's pure sex for IB use!

I'm on the verge of going for 3 IB12s in my S2000. These things are unbeatable.

Everytime I go back & reread this thread I come so close to pulling the trigger on a couple of these. I know I shouldn't be, but I'm afraid I'll be disappointed with the output.

Model what you are using now, then model the new ones. If you know what your actual output is, you can get a delta between the modeled response and the actual to give you an even better idea. Worst case scenario, watch the classifieds for a set to come up used and give em a try, if you don't like them you will most likely only be out shipping costs.

The AE IB is unbeatable/$/watt/lb. If you need more output look at the AV series. Once you factor in sensitivity it should be comparable to any sub on the market.

Would 2 15's equal the in car output of a single 15 in a ported enclosure?

Bare in mind, I am running my TC with a 1500 watt [email protected] ohm and I can get low 140's in output.

Curious because would love to have some usable trunk, less weight. Wife likes the current output.

It is very easy to conflate cause and effect that are unrelated in audio design. In fact, the entire audiophile industry is based upon this ease of fallacy.

hard to say for sure. I'm pretty much willing to bet on it.
depending on how you ported your box, you'll probably get much lower response with the IB setup. One thing is for sure, you wont have to have a huge friggin' box to get down to 30hz effortlessly.

(A mini-review...I started typing before cubdenno replied )

As the owner of one of George's (former) subs, I will say that anyone concerned with output shouldn't be...unless you want to hit 150dB. Or trying to seek the rainbow unicorn that is "SQL"

I've simply never heard a sub that was better...it's better in every way, in fact, than any sub I've used. It has so much of everything; goes deep, "hits" pretty hard, and can hit double bass kicks. People think big subs are for "booming" or "getting loud" but that's simply not the case.

This sub, in my opinion, is as if you have you have one of each 8" through 15" subs playing the frequency they do best. There is nothing it can't play...there is no slop...there is no lag in transients...there is no one-note loudness...

I don't believe I could sway someone away from an AE sub, aside from availability issues...if they needed a sub tomorrow. I also don't believe there are better IB subs out there for the money. With the sub and my two heavy amps, I'd venture to say I've added about 65lbs to my trunk, and the weight is right between the strut towers and above the gas tank. The baffle and sub weigh 35lbs together. Quite amazing.

John at AE says that with cabin gain, a single 15 can hit 142dB @ 20Hz. Just so happens I also have 300w on tap I'd like to fit another, but it's not happening at this time.

Yeah, don't you have like only 70-100 watts going to each of them?

Default Re: Acoustic Elegance IB15 4ohm car version (Idmax comparison)

yep. it's like this:
If I remove my subs and put a 4ohm dummy load on my sub amp, play a 0dB tone and measure the output (having not touched the gain from where it was on the amp/dsp) at about the same volume I typically listen to my music at I get about 90w @ 4ohm.

I think everyone who has heard my car has always had something great to say about the subs. My car's geometry has caused me headaches but it's not the subs' fault.

Default Re: Acoustic Elegance IB15 4ohm car version (Idmax comparison)

Very interesting.....

In car With the port firing forward I get a nice flat 30-70 hertz passband with about 2-4db deviation. The problem is that the enclosure is a single reflex bandpass and is holy fekk huge. I meter at the windshield sealed at like 143.4, with the box turned around port firing to the rear, I gain 1.5 db. (I bought the design from Pete Kulicki. Everything he has stated about in car response has been spot on. Including firing orientation output.)

I enjoy my system played loudly, It gets every type of music played through it. Just at high volumes. No competing just enjoying. Now though, there are times that I would love to be able to use the trunk. Wife approves of the rolling concert hall and does not want to sacrifice output. Plus, with the teenager son rapidly approaching a louder vehicle than mine, I have to stay at least competitive.I will have to seriously ponder this. My only hold back is that with the current economy, it is more difficult to sell off items if I don't like them.

It is very easy to conflate cause and effect that are unrelated in audio design. In fact, the entire audiophile industry is based upon this ease of fallacy.

"Heck yeah you can spend more to get the same sound."

With the limited availability of the IB15, they are rare to last in the second hand market unless you are trying to get full retail for them.
