The KSI Series 5 8081-CS 2×2 grid ceiling mount loudspeaker is our most popular model featuring a unique and innovative design in a very cost effective package. It’s right at home in any installation demanding superb sound quality with pleasing architectural appearance.


The 8081-CS offers smooth mid-range performance with powerful bass response through the use of our 8” bass-mid transducer and 10” optimally tuned passive radiator. Our 8” transducer features a paper laminated cone with a large 1-1/2” edge wound voice coil and a vented magnet structure. This 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 outstanding clarity and coherence along with wide frequency response and wide dynamic range. The use of high quality filter components assures a smooth transition at the crossover frequency. To further enhance the low frequency and mid-range reproduction of the 8081-CS, the backbox employs our anti-resonance fabrication. This construction technique utilizes our state of the art CNC machinery to give us an incredibly strong, vibration free and light weight enclosure, greatly improving the sound quality over the entire spectrum. The 8081-CS offers wide and evenly controlled dispersion, outstanding clarity and coherence, wide frequency response and a 100 watt power capacity. The 8081-CS is fully assembled, speeding installation to save both time and money.


The 8081-CS is optionally available fabricated from Duraflake fire rated particle board by ordering part number 8081-CS-FR.
