Really, the ID Max is very efficient and doesn't necessarily need all that much power to get going. Remember that twice the power is a 3 db increase, so for example if you gave the Max 500W RMS, then you'd lose 3 db compared to if you gave it 1000 (of course this is a general rule). The ID maxes work extremely well in low tuned ported because of their low resonant frequency of 20.2 hz. As far as other SQ subs, that's all subjective, and in this category, IMO there aren't any you're gonna find that'll take a lot less power.
Personally, I like the ID Max a lot better for both low end and midbass transition, but that's totally up to you. The Perfect has great SQ, I don't think you'd be disappointed with it. As far as SPL, it's a drastic difference, ID Max by a long shot, even if gave it the same power that you gave the Perfect it'd still hit harder.
Yeah, Jon and I both have 'em I've got more power to them then they need, but these guys are insanely, insanely loud. (Granted I've never heard two X.X.X 12s, only 1). SQ is great and the great midbass transition works well with my 2 way components. Something to consider Sean, it will let you get away with out having to use a 3 way component set(as jon mentioned wasn't necessary w/ the ID MAx). It's what pushed me to the ID Max over the X.X.X.
That's more than enough. 800 RMS is too much for a Perfect anyway. 20 hz is very, very low, but if that's what you want by all means go for it. The ID Max resonant frequency is 20 hz for the d4, 20.2 hz for the d2, so you'll have no negative effects of tuning that low. Personally I'd go around 25 hz, most people can't even hear to 20 hz due to little bits of hearing damage over the years. You'll rattle bones with that frequency and the right music though .
That was my plans i wanted to impress people with my sound quality out of the sub and the spl out of it since we do custom boxes for people and my car is the demo ps...if im right about the 25hz to 50 hz thats and octave higher right?
Not with the ID max particularly, I've heard it sealed, ported, AP, and passive radiator, and all sounded great. I've heard ABC boxes with other subs and for SQ, I wasn't impressed, SPL is good though. Snail shells are better for SQ than ABC IMO, but still not as good as traditional ported boxes. Just my opinion. It's just that you said that you wanted to impress people with SQ and SPL. I think if you could build a transmission line or passive radiator, you could impress people easily, TLs have a unique sound to them and sound fantastic if built properly. They are very hard to build correctly, though. You'll also have to build a VERY large box for TL.
jon the id max 12 d 2 v3 for 329.95 and the IDQ12D2 V.2 for 159.95
my question is other than power handling being less on the idq12d2 is the sq any less and does it still cover the midbass area the idmax12d2v3 covers like mazada man mentioned you told him cuz i can sacrifice the spl for saving in cost im mainly focused on sq for this project unless were talking tons less spl (136 db or close is fine for me)
ok im about to order one of these but which way would be better to go dual 4 ohm and be able to put 1500 rms into in on my mtx 81000d or go dual 2 ohm and be able to put 800 rms to it. I only plan on buying one. Ps...will i still get a factory warranty on this buying from here?
Not sure about the warranty, but personally I'd do the dual 2 ohm. 1500W RMS is going to be too much, and you'll risk damage to the sub in a normal application if you aren't careful. 800W RMS is plenty and you'll get the best SQ out of the amp with a 4 ohm load. Also, if you ever decide that one isn't enough and you want another one, two dual 2 ohm subs can be wired for a 2 ohm load giving 1500W RMS total, you don't have that flexibility with the dual 4 ohm subs.
