Our take on the QPOWER SINGLE 15″ SQUARE SLOT PORTED HEAVY DUTY VENTED SUBWOOFER ENCLOSURE BOX

The QPower QHD115VSQ is a single 15-inch vented subwoofer enclosure with a square slot port, built from 1-inch MDF on the face and 3/4-inch MDF elsewhere. It offers 2.7 cubic feet of air space and is tuned to 32 Hz, a low tuning that suits deep bass in a daily-driver system. The square port gives it a different look and airflow path than the round-port boxes most rivals sell at this size. It is a bare enclosure, so the subwoofer, wiring and amp are separate purchases.

Questions and answers

What subwoofer works with this box?
It is built for a single 15-inch subwoofer and gives 2.7 cubic feet of air space. Check your sub's recommended vented volume and port tuning before buying; a sub that wants a smaller sealed box will sound loose here.
What is the tuning frequency?
The box is tuned to 32 Hz. That is on the low side, so it favors deep bass over punchy mid-bass.
Is the subwoofer included?
No. It is an empty enclosure. You supply the 15-inch sub, amplifier and wiring.
How big is the box?
It measures 16.25 inches high, 21 inches wide and 18 inches deep. Measure your trunk or hatch before ordering.
What is it made of?
The face is 1-inch MDF and the rest of the box is 3/4-inch MDF, covered in charcoal carpet with spring-loaded terminals.
Does the square port change the sound?
The square slot port moves air like any vented port at the same tuning. It mainly changes the look and how the box is built, not the tuning itself.
