In-Wall Passive Subwoofer

The Goldwood Sound HD-S10 is a 10-inch passive subwoofer designed for flush-mount installation inside a wall cavity. It targets home-theatre builders who want deep bass without a bulky floor-standing cabinet. A separate subwoofer amplifier is required to drive the unit.

Replaces Freestanding Sub Boxes

This speaker replaces traditional enclosure subwoofers that consume floor space and clash with room aesthetics. The upgrade is worth it when a dedicated sub amplifier is already available and a clean, paintable grille is preferred over a visible cabinet. It fits a square cut-out of 10.6 by 10.6 inches with a mounting depth of 3.54 inches.

Sustained Low-Frequency Output

The 10-inch woven-fibre cone with butyl rubber surround delivers a frequency response of 26 to 200 Hz at 98 dB sensitivity and 8-ohm impedance. Spring-loaded raw-wire terminals maintain a secure connection during extended playback sessions. The ABS housing and Pressure Lock Mounting System keep the driver stable under continuous low-frequency excursion.

Questions about this item

What size cut-out does the HD-S10 need in the drywall?

The template shows a square hole of 10.6 inches by 10.6 inches, and the mounting depth behind the wall must be at least 3.54 inches.

How does the Pressure Lock Mounting System secure the speaker without hardware?

Flip the levers inside the housing after inserting the unit; they expand against the back of the drywall and clamp the frame tight.

Will the 10-inch woofer surround need replacing, and what wire should I run now?

The butyl rubber surround is durable but will age; pull CL3-rated in-wall speaker cable during install so you can rewire later without opening walls.
