Stealth Acoustics Invisible Speakers. All the sound without the fury. Primarily because the speakers are hidden behind your wall or wallpaper or whatever else you want to put in the way. From about $550.00 a pair.
The Stealth Acoustics model AX3 is a three-way, full-range loudspeaker system that becomes completely invisible after installation. The loudspeaker has a rigid frame which attaches directly to standard structural framing without the need for special mounting brackets. Once the feathering is complete the panel is ready for painting… Stealth Acoustic speaker panels are engineered for optimum audio performance with 4 coats of latex paint applied to the surface. A light spray-on “orange peel” texture can be applied, or even light wallpaper. Heavy knock down or trowel finishes are not recommended.
