  Features

  Custom Install Passive Subwoofer: The Bowers & Wilkins ISW-3 is an incredibly versatile and compact passive subwoofer, capable of providing high-quality bass output in spaces that may have not been possible before. It can be placed in a variety of locations without causing vibrations. The ISW-3 houses two 6.5″ paper/aramid fiber cone woofers with rubber surrounds and requires an external subwoofer power amplifier (sold separately).

  Installation Options: The Bowers & Wilkins ISW-3 passive subwoofer offers four possible installation applications – In-Ceiling, In-Wall, Under-The-Floor, or Kitchen-Cabinet. Four angled “L”-brackets will secure the passive subwoofer enclosure in place.

  • In-Ceiling: The passive subwoofer will fit between joists with standard 16″ or greater spacing, such that the visible louvre straddles the gap between them. A clearance of 10″ or greater behind the underside face of the joists is required.
  • In-Wall: The passive subwoofer is too deep to fit into a standard nominal 4″ thick wall, but may be fitted into custom furniture or closet that accommodates its depth and that has studs with standard 16″ or greater spacing. In most situations, the visible louvre will be required to be low on the wall, just above the skirting board. In that case, the cabinet will be oriented with the cowl at the bottom.
  • Under-The-Floor: The speaker will fit between joists with standard 16″ or greater spacing, such that the visible louvre straddles the gap between them. A clearance of 10″ or greater behind the top of the joists is required. This subwoofer is not recommended if the floor is to be covered by a thick carpet. Very short pile carpet, such as carpet tiles, may be accommodated with care.
  • Kitchen-Unit: The subwoofer will rest on the bottom shelf of the kitchen cabinet and vent through the toe-kick panel below the door.

  Note: See the “Custom Installation” booklet for further installation instructions and details.

  Gold-Plated Spring-Post Terminals: The B&W ISW-3 passive subwoofer is outfitted with gold-plated, spring-post terminals that will accommodate bare speaker wire (up to 12AWG), pin connectors, and banana plugs (single only). The gold-plated terminals provide excellent audio signal transfer and resists corrosion.
