What subwoofer works with the RSQ15?

It is a single 15-inch sealed enclosure, so it fits one 15-inch subwoofer. Match the sub's recommended sealed airspace to the box's internal volume before buying.

Is a sealed box better than a ported one?

Sealed boxes like this one give tighter, more accurate bass and a smaller footprint. Ported boxes play louder and deeper but can sound boomier and need more space.

Does the box come pre-wired?

The description covers the enclosure only: MDF, glue, staples, silicon and carpet. No terminal cup, wire or mounting screws are listed, so plan on adding them.

Why does the MDF thickness matter?

Thicker 3/4-inch MDF flexes less under heavy bass, so the subwoofer moves air instead of the walls. That keeps output cleaner at high volume.

Is it built in the USA?

Yes. Rockville says the enclosure is made in the USA from Grade A 3/4-inch MDF, cut on precision machinery by a team that has built enclosures for over 20 years.
