Description

Bring deep, controlled bass to your home audio system with the OSD Audio SMP200 and IWS8 in-wall subwoofer package.

Perfect for home cinemas, media rooms, or living spaces where floor space is limited, this discreet system delivers impressive low-frequency performance without the clutter of a floor-standing subwoofer.

The OSD Audio IWS8 8" in-wall subwoofer blends seamlessly into your room design, providing a clean, flush-mounted installation with powerful bass response.

Driving the subwoofer is the SMP200, a 200W mono amplifier designed specifically for in-wall and in-ceiling subs, ensuring efficient power delivery and precise control over your low frequencies.

FEATURES

  • Dedicated Subwoofer Amplifier: The SMP200 delivers up to 200W of power, perfectly matched to the IWS8 for tight, punchy bass.
  • Custom Low-Frequency Driver: The IWS8 features an 8" long-excursion woofer designed to deliver deep, resonant bass from within the wall.
  • Space-Saving Design: Flush-mounted installation keeps the subwoofer hidden in the wall, freeing up floor space while maintaining premium sound quality.
  • Adjustable Controls: Fine-tune your bass performance with variable crossover and phase controls on the SMP200, ensuring seamless integration with your main speakers.
  • Durable Build: Both the amplifier and in-wall subwoofer are engineered for long-lasting performance with high-quality components.
  • Versatile Applications: Ideal for home theatres, living rooms, or any multi-room audio system requiring discreet yet impactful bass.

This package combines performance and practicality, making it easy to achieve rich low-end sound in a discreet and stylish setup.
