Q-Power Shallow Single 12" Sealed Truck Subwoofer Box 18.25x13.25x5.25(Damaged)
10 March 2021
Get's the job done. Will not sound good, but that never stops anyone.
Reasonable build quality. A couple notches below an Atrend or Ground Shaker, but this is typically quite a bit less expensive. Good looking black carpet (not gray). 5/8" construction throughout. Cheap, basic terminal is the weak build point, but at least it's mounted on the side. For whatever reason most slim boxes have to terminal mounted on back, meaning you can't use banana plugs and/or your wiring will be jammed up against the wall in a truck install.
How will it sound?
Mediocre, as you should expect. This box houses a 12" sub and only has an actual internal volume of around .45 cubic feet (12.73L) before factoring in sub displacement, etc. Most slim 12" woofers need several times that to achieve even a tolerable .8 Qtc, much less a smooth "707" response. But whatever. So many people think you should simply jam the largest sub into the smallest box. This is the enclosure for you if that's your mindset.
My install? I'm using this as a back box for a vintage 6.5" sub, aligned to a 31 Hz Fb. I picked this up for around $20 in "damaged stock", so it saved me several hours of box building time.
