Absolute USA SAG12 Heavy Duty Sealed Back-Angle Single 12-Inch Subwoofer Enclosure Box

It is basic, functional, but fits perfectly in my trunk with small amount of space. I used to have huge dual 12" subwoofer that used 1/2 the trunk. Also,I could never carry anything long since I could not lower the seat.This device? Is perfect for size.. maybe even a bit small... but I don't mind. I got a nice speaker for $50 and a powerfull amp. It sounds good... for filling in the lowest 50HZ that my regular speakers can't get to.It will never shake the doors that much, but I don't need that. Just I can move it easily, take it out when I have to transport someone to airport, put it back and still it works well.Oh, it didn't hurt that in the shipping material for this box, I found a second identical new box.. It seemed to be 2 boxes for the price of one.Sweet.....

they work exactly as i expected them to

Well made, but just didn't give the sound and fullness I desired. Went back to my old box because it had the recommended deminsions to get the best quality.

Love it and the service was exceptional

Compact, perhaps just a little too compact for most 12" subs. But still pleased with bass using a HIFONICS HFX12D4 powered by a Rockford Fosgate amp. Could probably be .5 cf larger for a perfect match to the speaker I am using but good enough.Construction quality is adequate and terminal hardware is good. The fiber damping material is not enough for any acoustic effect, but may keep your internal wire from rattling against the box.
