Power handling, transient response, flat response, deep bass,

Not available anymore.

Without question, the best sub I've heard. And I've heard them all! The only non-5 star review I've read here makes sense. If you want deep bass in a sealed box, you need a 1.2 cubic foot sealed box. .8 with the magnet and basket of this sub is WAY too small for deep bass.

pounds hard. precise, even in a ported box, handles 200watts rms above recomended rms level but it seems like it could take even more. looks amazing as well

wanted two but could only find one and they have been replaced by the newer TDX and now the D9 line, so its very difficult to find these subs anymore

wow, i never thought this sub would ever be this loud and accurate. i was worried that one wouldnt be enough, moving from 2 type R 12's, but I couldnt imagine it being any louder without hurting my ears. its just as loud if not louder then the R's and im running one less sub and 200watts less rms. I am running it off a kenwood KAC-9102D amp with 800w rms in a spec ported box, and it doesnt even look like its working hard at all yet it shakes everything in my whole car, it looks great, and the sound quality is amazing

Very good sound quality and output when installed in a spec ported box. Excellent build quality, reasonable clearance price. Able to easily handle much more power than rated at. Small box requirements, and the flexiblity to be installed either ported or sealed.

Inability to play low bass notes when installed in a spec .8 cu. foot box. A 12 inch sub should be able to play some low bass. Two star rating for sealed box installation.

I wanted to run one high-powered 12 inch sub in my car, to replace two excellent sounding but heavy Eclipse Aluminum 12's. The Eclipses' in thier 2 cu. ft. MDF box lowered the rear of my Accord V6 2 inches. I picked up a Mackdaddy 12 on clearance from the local dealer, and tried running it in a spec .8 cu. foot sealed box loosely filled with fiberfill, and crossed over at about 70 hertz with a 24db slope. After proper break in, I started to crank the music up. The woofer sounded incredibly accurate, better than any other sub I've heard. But the woofer COULD NOT PLAY LOW BASS, even off of regular Pop and R and B tracks. The woofer would "bog" terribly, and sounded like an eight incher. Frustrated, I built a spec 1.25 cu. foot ported box. The low bass response was much better, and had substantially more output (3 db more per the manual). With the ported box, the woofer plays low bass a lot better, and still has pretty good accuracy despite the fact that it is ported. The woofer is almost as loud as the two Eclipse 12's I used to run. I am feeding the sub 850-900 watts from a bridged Rockford Fosgate Power 851s.

Great SQ no matter how loud!! Takes 800w and beggs for more!! Gets very loud even in a sealed box!! Great looking sub!!

Needs lots of power to get it going in sealed box.. SQ ave in vented boxes!!

2 12"svc4 Mac's 1.25 sealed box 2 Avionixx 800.2 1 for each sub 800w each I beleave this is the best SQL sub for the money! The bass aint to punchy nor boomy ethier.... It hits every notes clean and perfectly. Now in a sealed box with 800w each these suxer pounds like a mofo.... But even at extream loud volume the sub still sounds very clean... Also the magnet looks really nice so this would be a great sub to invert to show it off...!

These subs are awsome. Very accurate and very loud. These subs drop lower than most all I have heard. They have no destortion while playing at high watts.

None.

These are the best subs I've ever owned. I have two MacDaddy 12.4's. It is hard to breathe when they are turned up. I am pushing them with a Esoteric E7 152 at two ohms. I hit 151.8 in my Jeep Grand Cheorokee.

This sub is truley awsome! very very accurate sub(Great SQ), but also great sub for someone who likes it loud. Also a very great cold weather sub, you can walk right out into a Zero degree day, get in your car and start hitting em like it was summertime. and thats good for me cause i live in wisconsin.

Needs alot of power to get going, but thats about it, they also sound wierd when you open the trunk and watch them "hit". but those are petty weaknesses.

I bought two 12 Diamond HEX mac daddy 12.8's and really love em, compared to my audiobahns, there is no comparison, i am running a Premier PRS-X720 to them, and soon am planning to add one more so i would have 3 12's, but for right now i am more then content with them, and also a great sub if you like to have a custom install, because the magnent is sweet looking. they play great to any type of music. just overall i love the sub!

everything, it performs so damn good

you're kidding right?

Hard to breathe when it's REALLY being pushed.
This is the BEST sub I've ever owned and it's performance causes heads to turn all the time. I own the dual voice coil version and it's pushed by a mmats d300hc so it receives 1200 watts, and it NEVER complains!!!!!!!
