  • TypeSubwoofer
  • Deep bass down to 26 Hz from 10" woven fiber cone

Four-Pack In-Wall Subwoofer System

The Acoustic Audio HD-S10 bundle supplies four 10-inch flush-mount passive subwoofers plus four matching WS1005 amplifiers. Each driver uses a woven-fibre cone with butyl rubber surround and installs through a 10.6 by 10.6 inch square cut-out. The Pressure Lock Mounting System secures the ABS housing to drywall without separate hardware, leaving a low-profile grille that can be painted.

Home-theatre builders wanting hidden bass

This kit suits installers who can run speaker cable from a receiver to the supplied amps and then to each in-wall location. It does not suit buyers who need a self-powered subwoofer with its own line-level input, nor rooms where cutting a 10.6-inch square opening and providing 3.54 inches of mounting depth is impractical.

26 Hz low-frequency extension

The passive subwoofers reach 26 Hz at 98 dB sensitivity measured at 8 ohms, while each WS1005 amplifier delivers 200 watts with a 50 to 200 Hz crossover range. That combination determines whether the system can reinforce the bottom octave of movie soundtracks in your listening space.

Questions about this item

Will the 10.6" square cut-out fit the drywall opening I already cut for my old in-wall speakers?

Each subwoofer needs a 10.6" x 10.6" square hole and 3.54" mounting depth; measure your existing opening against those dimensions before installing.

How can I confirm the 26-200Hz frequency response and 98dB sensitivity are being delivered after setup?

Play a calibrated test tone sweep through the WS1005 amplifier and measure output at the listening position with an SPL meter; the response should roll off near 26Hz and reach 98dB at reference level.

Does the 4-pack include the WS1005 amplifiers and all wiring, or must I buy speaker cable separately?

The set includes four HD-S10 passive subwoofers and four WS1005 amplifiers; you will need to supply raw speaker wire for the amplifier-to-subwoofer runs and an RCA or LFE cable from your receiver.
