Four-Pack Passive Subwoofers

The Goldwood Sound HD-S10 set provides four 10 inch flush-mount passive subwoofers designed for in-wall home theatre installations. Each unit requires a separate sub amplifier driven from a receiver RCA sub output. Builders seeking a hidden low-frequency foundation without floor-standing enclosures will find the quartet suits multi-room or large single-room layouts.

Pressure Lock Mounting System

The proprietary Pressure Lock clamps secure each housing to drywall without screws or additional hardware, cutting installation time. A square cut-out of 10.6 by 10.6 inches and a mounting depth of 3.54 inches are the only structural requirements. Spring-loaded raw-wire terminals accept CL3-rated in-wall speaker cable directly from the chosen amplifier such as the Goldwood WS1005 or SA200.

Paintable ABS Housings

Durable ABS cabinets and removable grilles arrive paint-ready so the visible surfaces blend with any décor. The 110 woven-fibre cone with butyl rubber surround delivers a 26 to 200 Hz frequency response at 98 dB sensitivity and 8 ohm impedance. Overall dimensions of 11.89 by 11.89 inches keep the profile low once recessed, leaving the room visually uncluttered while the passive design keeps heat and electronics out of the wall cavity.

Questions about this item

Does the 10" woven fiber cone and butyl rubber surround need periodic replacement?

The cone and surround are built for long-term use with no published replacement interval.

What limits output first during extended low-frequency playback — the 98 dB sensitivity or the 200 Hz upper response?

The 200 Hz upper limit defines the usable band; sensitivity stays constant at 98 dB.

How much heat does each passive subwoofer generate when driven all day by an external amplifier?

The passive units produce no heat themselves; only the separate sub amplifier warms up.
