Is a sealed box better than a ported box for my subs?

Sealed boxes give tighter, more accurate bass and a flatter response, while ported boxes play louder around their tuning frequency. If you want punch and control over maximum volume, sealed is the better fit.

How much air space does each chamber have?

Each of the three chambers provides about 1.87 cubic feet of air space. Check your subwoofer's recommended sealed volume to confirm it matches.

Can I use just one or two subs in it?

Yes. The chambers are separate, so you can run one, two or three 12-inch subs and leave the unused holes empty without changing the tuning of the loaded chambers.

What subwoofer size fits?

It is built for 12-inch subwoofers. Measure your driver's cutout and mounting depth against the box before installing.

What is included in the box?

The enclosure itself with its terminal cups. Subwoofers, wiring and mounting hardware are not included.

Does it come with a warranty?

QPower backs it with a one-year manufacturer warranty.

Our take on the QPower BASS12 3 Hole 12" Sealed Car Subwoofer Enclosure Box

The QPower BASS12 3HOLE is a sealed MDF enclosure with three separate chambers, each giving a 12-inch sub about 1.87 cubic feet of air space. Sealed boxes trade some output for tighter, more controlled bass, and three chambers let you run one, two or three subs without the empty holes changing the tuning. It is aimed at people building a loud daily system who want a sturdy pre-built box rather than cutting MDF themselves. Against ported boxes it gives up peak volume, and against cheap particle-board boxes it is heavier and better braced.
