Summary:
I am redoing my previous review which can be found below. So far people seem to either enjoy this sub or hate it. Many of the people who hate it have not given it a proper chance. I would like to tell anyone considering this subwoofer should not go with a sealed box because they suck. The best alternative is to go ported and tune somewhere between 23 and 30 hertz.

The worst part of this sub is that it takes a very very large box to make it sound good. Most people probably have not put it in the right box. At best it wants an 8 cubic foot box and at least 4 cubic feet. If going for the larger box tune to 23 Hz. You will get a pretty flat response all the way to 20 hertz. If going for the 4 cubic foot box tune to 30 hertz. It will not go as low as the other box BUT you will get really good output at 35 hertz.

If you want a sub that you can shove in a ready made crappy box then look somewhere else. The new shallow series from jl audio can be put in amazingly small boxes.

An alternative to having a huge box size would be iso-barik loading. You should look into this if you want great low frequency response. problem is it takes 2 subs for about the same spl and you need to power 2 subs. Good thing is you can halve the box size.

Strengths:
price and value. have only impressed people since i have had it.

Weaknesses:
even when i give it the right amount of power I have still pushed it to where it maxes out on it's excursion and have to back off a little.

Summary:
I bought this sub after I heard a friend talk about them. I have never heard a sub hit with the clarity this one has. even mounted inverted I still couldn't turn it up more than half way before i couldn't handle the volume. ran it with a 1200 watt max 2 channel monoblock SPL amp. and you know power when your car becomes the box for the sub. had it for about a year and it still hits as strong as the first day i hooked it up.

Strengths:
great performance as well as good looks.

Weaknesses:
none that i've found
