Bass is a vital element in our enjoyment of sound. It’s true for both music and movies, and it’s as true for custom installation as it is for an audiophile’s two-channel hi-fi. The ISW-3 is an incredibly versatile and compact in-wall and in-ceiling subwoofer, capable of providing high-quality bass output in spaces that may have previously missed out on this vital element, including kitchen cabinets! Its balanced design, featuring 2 x 6in drivers, means that it can be placed in a variety of locations without causing vibrations. Powered by a separate audiophile-standard 250W Class D amplifier the SA250, the system keeps its cool even when you listening to demanding movie soundtracks at high volumes.

  • Dual 6" Drivers in Balanced Configuration: Delivers tight, controlled bass with minimal cabinet vibration, allowing flexible placement in walls, ceilings, or millwork.
  • Ultra-Compact Form Factor:  At just 100mm deep, the ISW3 fits into tight spaces, including shallow wall cavities or behind kitchen cabinetry.
  • External SA250 Amplifier Compatibility:  Paired with the 250W SA250 Class D amplifier (sold separately), ensuring dynamic power and stable performance under pressure.
  • Low-Profile Magnetic Grille:  Blends seamlessly into its surroundings for a nearly invisible look, maintaining room aesthetics.
  • Versatile Installation:  Ideal for small rooms, custom cabinetry, or home theatres where floor space is at a premium.
