Quality

For the price its built right. It is 800w rms rated which I did not know. Still held up to the sex12d4s on 1400w

great value

The following review is for a previous version (2SL12-2.0-BLACK).

This is a Sonic store brand but just as good as a top name brand box for the price you can't beat it.

Good

The following review is for a previous version (2SL12-2.0-BLACK).

Good, Solid, basic box. Terminal's are ehhhh but don't let that scare you away. Good for any small-box 12's out there. Packing and shipping was dope.

Great!

The following review is for a previous version (2SL12-2.0-BLACK).

Worked great, small and compact but still provided enough air space so it didn't take up my whole trunk. Good quality.

poor construction

The following review is for a previous version (2SL12-2.0-BLACK).

i received this box and opened the package carefully and immediately notice a long cut in the carpet exposing the wood color. also on the inside of the box, the seams were not filled properly and there were gaps where the box could leak and cause the sub-woofer to not sound properly. i'm very disappointed in the quality of this box.

You get what you pay for

The following review is for a previous version (2SL12-2.0-BLACK).

Carpet is very cheap, ok for the looks of the box. But overall feels cheap. Ok sound, i bought it more so just to help sell a sub i had laying around.
