Frameless Subwoofer For Inconspicuous Bass Reproduction

Minimize the visibility of your home theater audio system while maximizing bass performance with the OEM Systems 8" In-Wall/Ceiling Frameless Subwoofer (Single). Designed for in-wall or in-ceiling installation, this frameless subwoofer integrates seamlessly into your home’s decor. The grilles can even be painted for a perfect match.

  • Poly woofers with butyl rubber surrounds
  • Proven toggle mounting system
  • Includes both round and square grilles
  • Rattle-free, low-profile paintable grilles
  • Used individually or in multiples

The 8" round subwoofer features a unique, shallow polypropylene cone to deliver strong, crisp low bass reproduction. The low frequency transducer also has a one-piece surround/damping ring to reduce disruptive resonances in the unit’s mechanical substructure.

The subwoofer comes with both round and square grilles, allowing you to create the best installation appearance for your home. Each grille is held in place with 24 specially-shaped neodymium magnets, which line the entire perimeter of the hidden frame.

For superior performance and room integration, OEM manufacturers recommend connecting multiple subwoofers (two, three or four) to one OEM 500 Watt Class A/B Model 500 Amplifier. This helps minimize standing waves to offer more uniform bass reproduction throughout the room.
