I bought 2 of these beauties to house 4 boston pro 12.5LF subs, as they require an enclosure of 1 cu/ft each, the result is a tight, loud, accurate bass response. Easily the best sounding match i've heard let alone owned. I also prefer the look of the MTX BS212S as a straight rectangular box, no crazy angles or curves. The build quality on these enclosures are flawless and should well outlive the lives of many subs. I would however recommend a sound dampener be inserted.

Great value, tight bass & even better output when you have a premium deck installed. I have two 12" Kenwood KFC3012 1200w subs installed in this box hooked up to a Kenwood KAC9104D 1800w max Mono Amp and my mirrors are very messy while the bass goes from the trunk through my body and into the car next to me..heh heh. I thought my ears would ring, but if you adjust your gains on your amp you can get quality sound even at low volume. This box is versatile with very little discrimination...it handles, Jazz, Pop & Rap (but not all types) depending on the acoustics. Construction is rock-solid but plain and is very heavy due to the MDF used. If you want solid thump at a great price, this is a worthy pick. This box WILL NOT fall apart like others in the same price range. Just remember to purchase a separate amp to run other speakers because the sound from the box will drown them out.

Oh, yeah, props to the packaging and fast shipping, box came in 3 days on standard shipping. Peace, out!
