The KSI Series IV 811-WM -HP is a high performance wall mount loudspeaker designed for fast & easy mounting in drywall and other flat substrates. It is designed for retrofit applications in existing substrates, hence the absence of a backbox. It’s a perfect choice for corporate, government, retail and private residences requiring wall mounted loudspeakers with high end performance and pleasing architectural appearance.


The 811-WM-HP offers smooth midrange and bass response through the use of our 8” cast frame bass-mid transducer. This 8” transducer features a lightweight mica filled cone providing exceptional voice and music intelligibility. High frequencies are handled by our 25mm horn loaded dome tweeter. This high end transducer provides very smooth upper octave response for an “open” sound quality with wide dynamic range. We have improved our proprietary filter network using very high tolerance components which are inaudible at the crossover frequency. This provides outstanding clarity and coherence with very wide frequency response and high power capacity. This careful attention to detail has led to a loudspeaker with outstanding clarity and coherence along with very wide frequency response and high power capacity. Mounting is fast & easy with our continuous compression clamps. After a cutout of 14” h x 9” w is made, fiberglass dampening should be added to the wall cavity to provide smoother frequency response. Simply wire the 811-WM-HP, place it through the opening and tighten the clamps. Snap on the grille and you’re finished! This fast installation procedure is ideal for facilities where down time is of paramount concern.


All KSI ceiling and wall mount loudspeakers may be used in combination with the 811-WM-HP, providing unlimited solutions for your audio environment.
