Image Dynamics IDMAX12 D4 V.4

Best sound quality/spl sub period

I have had many subwoofers in my life but this is by far the best for sound quality and SPL that I have encountered. In addition this subjects and a small cubic foot box which makes it ideal for fiberglass enclosure's. I am using this subwoofer in conjunction with A jl audio HD 750/1 monoblock amplifier and it sounds amazing! I highly recommend the subwoofer to anyone that wants SQL for the price and the quality I cannot think of many that meet or exceed this one.

WOW!

I had never heard of Image Dynamics before, until Sonic recommend their IDAMX 12 as an alternative to the JL Audio W7 12. I wanted a sub that could get loud but also maintain good sound quality. The Image Dynamics IDMAX 12 did not disappoint. I think it would be hard to beat it in a sound quality competition, honestly. It sounds amazingly clean, accurate, and tight, even in a ported enclosure. And when you put some power to it, it transforms into an absolute monster. I have mine powered by a BASH 500S subwoofer amp. If I even turn it up to half volume it shakes my six bedroom house, literally. I have tried turning it up all the way and the sub just drinks the power, but I don't leave it up for fear of clipping the amp. I would love to hear this beast on 900 watts. I think 1,000 watts continuously might push it to its limits. Even so, it performs impressively on just 500 watts. All in all, I would definitely recommend this sub to anyone looking for a high output driver that can maintain its composure at high volumes. The sound quality is impeccable. The build quality is solid. And the aesthetics are clean and simple.

VERY VERY NICE SOUNDING

I bought this sub for SQ and it also gets loud while keeping its composure.
Wanted a Focal K2 E30 KX but had a hard time with the $1000 price tag.
I have Focal Performance 165AS3 in the truck doors. I built a sealed fiberglass box for the IDMAX12. It is about 1.3cu ft. JL audio HD750 for the sub. For the Focals i'm running a JL HD 600/4. Thinking on getting a Audio Control DM608 for speaker processor for more control on the Focals.
This sub completes this setup nicely. I cant believe how hard it hits and how great it sounds! The deck is a Sony MEX-GS620BT.

not as expected

wasnt very impressed its loud and cant handle more than 750rms not as clean as i hoped the idq sounds way better to me for sq purposes
