Flush-mount 10" subwoofer and amp set

The Acoustic Audio HD-S10 combines a 10-inch woven-fibre cone passive subwoofer with the WS1005 amplifier in a single in-wall package. It is built for home-theatre or stereo listeners who want deep bass without a floor-standing cabinet.

Replaces bulky floor subwoofers

The pressure-lock mounting system clamps the 11.89-inch square frame into a 10.6-inch cut-out with no extra hardware, so the jump is worthwhile when room layout or décor rules out a separate enclosure. The amp accepts LFE or RCA feeds from any receiver and drives the speaker through raw-wire outputs.

Sustained low-frequency output

The passive woofer delivers a 26–200 Hz response at 98 dB sensitivity and 8-ohm impedance, while the amplifier provides 200 watts total system power across 50–200 Hz at 4–8 ohms. Volume and crossover knobs let you match level and blend to the main speakers for consistent performance during extended listening sessions.

Questions about this item

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

The subwoofer fits a square speaker hole of 10.6" x 10.6" and requires a mounting depth of 3.54". The overall speaker grille measures 11.89" x 11.89".

How does the Pressure Lock Mounting System secure the subwoofer, and what is the common mistake?

The system clamps the ABS housing directly to drywall with no hardware needed. The common mistake is not tightening the clamps evenly, which can leave the unit loose or misaligned in the wall.

When will the passive subwoofer amplifier need attention?

The WS1005 amplifier runs continuously when the system is powered. Over time, internal components such as capacitors may degrade. If volume or crossover controls become noisy or the unit fails to power on, the amplifier will need replacement.
