The KSI 501 is the smallest loudspeaker developed to
meet the demands of today's digital technology.
The 501 offers smooth midrange and bass response through
the use of our 5.25" bass-mid transducer and 8" optimally
tuned passive radiator. Our 5.25" transducer faithfully
reproduces the critical midrange frequencies so critical for
voice and dialogue applications. Coupling this to our 1"
pure titanium dome tweeter gives the 501 outstanding
clarity, coherence and wide frequency response with moderate
power capacity. Our CNC routing machinery enables us to fabricate
the 501 enclosure to the tightest tolerances. High strength
to weight ratio and the absence of vibration in the enclosure
means you here 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 501 making it rival loudspeakers costing
The KSI 501 can be easily wall mounted with KSI's optional
wall mount bracket.
