Description

The OSD Audio IWS8 is a discreet 8" in‑wall subwoofer that adds deep, room‑filling bass without taking up floor space.

Ideal for home cinemas and living rooms, it blends seamlessly behind a paintable grille while delivering impactful low‑end for movies and music.

Built around a robust polypropylene woofer with a butyl rubber surround and an easy dog‑leg mounting system, installation is straightforward.

As a passive design rated up to 150W at 8Ω, pair it with a dedicated subwoofer amplifier for the best results. Sold individually.

FEATURES

  • 8" Polypropylene Woofer: Produces tight, controlled bass that enhances soundtracks and music.
  • Butyl Rubber Surround: Durable, high‑performance suspension for low distortion and long‑term reliability.
  • 150W Power Handling (8Ω): Works with a wide range of subwoofer amplifiers to suit different room sizes.
  • Slim 3.63" Mounting Depth: Fits standard stud walls (with 0.5" drywall) for a flush, space‑saving install.
  • Dog‑Leg Mounting System: Quick, secure fit after the cut‑out for a clean, professional finish.
  • Integrated Rear Dust Shield: Protects internal components and keeps the wall cavity cleaner during install.
  • Paintable Grille & Frame: Spray to match your décor so the subwoofer virtually disappears.
  • Cut‑Out Template Included: Helps mark, cut and paint for a neat, consistent result.
  • 40Hz–200Hz Frequency Response: Adds weight and impact to your system’s low end.
  • Passive Design – Requires Subwoofer Amplifier: Choose the right amp to tailor bass to your space.

Bring cinema‑grade bass to your room with a neat, built‑in finish.

Note: This product requires a separate subwoofer amplifier in order to work. We recommend the OSD Audio SMP200
