Three-Pack In-Wall Subwoofer System

The Goldwood Sound HD-S10 pack supplies three 10-inch passive subwoofers and matching WS1005 amplifiers for whole-room bass. Each driver uses a woven-fibre cone with butyl rubber surround and fits a standard square cut-out. Spring-loaded terminals accept raw speaker wire for quick wiring.

Suits multi-room installs, not single-box upgrades

Builders running discrete zones from one receiver will appreciate the flush housings and Pressure Lock mounting that needs no hardware. The passive design demands an external amp channel per sub, so buyers wanting a self-powered single unit should look elsewhere.

200-watt amplifier per channel decides fit

Each WS1005 amp delivers 200 watts into 4-8 ohms with 50-200 Hz response, volume and crossover controls, plus LFE and RCA inputs. If your receiver cannot supply pre-outs or you need higher output per zone, this power level will limit performance.

Questions about this item

How do I install the subwoofers using the Pressure Lock Mounting System and what step is often missed?

Cut a 10.6" x 10.6" square hole, ensure at least 3.54" mounting depth behind the drywall, insert the 11.89" x 11.89" housing, then tighten the Pressure Lock clamps until they grip the drywall firmly — the step often missed is verifying the clamps have fully engaged before releasing the unit.

What maintenance or replacement will the subwoofers and amplifiers need over time?

The 10" woven fiber cone with butyl rubber surround is durable, but the surround may eventually dry out after many years; the WS1005 amplifiers have no user-serviceable parts, so if an amp fails it is replaced as a unit — grilles are removable and paintable for cosmetic refreshes.

What limit appears first when the system runs at high output for long periods?

Each WS1005 amplifier delivers 200 watts total system power with a 50-200 Hz frequency response at 4-8 ohm; sustained high-level playback will hit the amplifier's thermal protection or its 200-watt ceiling before the 98 dB sensitivity 8-ohm drivers reach their mechanical limits.
