KSI 8081-CS-FR 2x2 grid ceiling mount loudspeaker is our most popular model featuring a unique and innovative design in a very cost effective package. The 8081-CS-FR offers smooth midrange performance with powerful bass response through the use of our 8" bass-mid transducer and optimally tuned passive radiator. Our 8" transducer provides superb voice reproduction for greatly improved intelligibility not found in competitive loudspeakers. Coupling this to our 1" pure titanium dome tweeter gives the 8081-CS-FR outstanding clarity and coherence along with wide frequency response and moderate power capacity. To further enhance the low frequency and midrange reproduction of the 8081-CS, we have re-engineered the backbox to feature our anti-resonance fabrication. This construction technique utilizes our state of the art CNC machinery to give us an incredibly strong, vibration free and low weight enclosure, greatly improving the sound quality over the entire spectrum.
