The KSI 811-HP is the companion to our popular 8081-CSHP
developed to meet the demands of today's digital technology.
The 811-HP offers smooth midrange 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 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. Components in a crossover
should not be heard, so KSI engineers designed a filter
network using high tolerance devices which are inaudible at
the crossover frequency. 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.
Our CNC routing machinery enables us to fabricate the 811-HP
enclosure to the tightest tolerances. High strength to weight
ratio and the absence of vibration in the enclosure means you
hear only the highest quality audio, not rattles, buzzes or
squeaks. And all of our transducers are fully sealed to the
enclosure with silicone sealant for a complete air tight seal.
This attention to detail greatly improves the overall performance
of the 811-HP making it rival loudspeakers costing much
The KSI 811-HP can be easily wall mounted with KSI's
optional wall mount bracket.
