It's Cool

All my friends say that thix is the coolest box they have ever seen. The funny thing is that my box cost half as much as theirs. Very sturdy and worth it.

Amazing box

I bought this box for my 2 kicker cvrs which i also bought from this site and they sound excellent together. Get this box if you want yours subs to look cool and hit hard.

Don't Order This

This product is no longer what you see in the photo. Sonic is being supportive of the problem, but the manufacturer no longer makes the product like this and now the 2 cones are solid black, mounted onto the plexiglass with self tapping screws, and really pretty ugly.

Install was interesting since the box is sealed on the back, so connecting cables was rough, then it came with no screws for mounting anything, and the fiberglass didn't have proper predrilled holes for the screws, so they just kinda stick out instead of being able to drop flat with the fiberglass. The fiberglass cut wholes are also terribly tore up, like a poor drillbit was used that left ridged edges that are "covered up" like makeup on a zit with these black plastic cones.

I did get 3 years of warranty free for the problem, so I guess if I have problems I'll just use the warranty to get something that works.

Pretty good..

I would consider this a bandpass, not a sealed as there are two chambers and one is ported. Compared to almost all other bandpass boxes I've heard, this one can produce higher frequencys but the overall clarity isn't as impressive. If I could do it over i would likely buy a q-logic enclosure instead.

By Andrew on December 22, 2006


Great Buy!!!!!!

This Box is great for the price and it has the looks to kill. It looks great and it hits hard with it front ported design. The only thing that I really didnt like about it was it only holds regular size subs not double stack magnets, other than that, its a great buy!

By Blanche on October 19, 2006


Cool looking box

I had installed this product into a friends car and the box looks great. Also, the ports work well. Remember a ported box is better for louder bass for music like hip hop. The installation of the subwoofers were a bit of a pain but other than that the box looks awesome.
