What subwoofer works best in this box?

A 12-inch sub designed for sealed enclosures. Check the sub's recommended sealed volume against this box's internal airspace before buying.

Does it come with wiring or a terminal cup?

No. It is an empty enclosure, so you add your own terminal cup, speaker wire and mounting screws.

Sealed or ported for tighter bass?

Sealed. This box gives tighter, more controlled bass than a ported box, but less output at the lowest notes.

Can I mount the sub facing up or sideways?

The box is built for a standard forward- or rear-facing install. Keep the sub clear of obstructions and secure the box so it does not slide.

Is it worth it over building my own box?

If you want a finished, carpeted enclosure without cutting wood, yes. A custom box can be tuned closer to your sub, but takes tools and time.

Our take on the Q Power QSMPSQ12E Empty Subwoofer Box 12" Square Sealed Enclosure

The Q Power QSMPSQ12E is an empty sealed enclosure for a single 12-inch subwoofer, built as a square box with a carpeted finish. Sealed boxes trade a little deep-bass output for tighter, more controlled bass, so this suits a sub that is designed for sealed alignment and a listener who wants accuracy over boom. It is a plain, budget-level enclosure: no terminal cup or wiring is included, so you add your own. Compared with ported boxes, it takes less space and is more forgiving of placement, but it will not play as loud at the lowest frequencies.
