The three key factors significantly affecting speaker sound quality are: ① the sound quality of the speaker drivers used, ② the shape of the speaker enclosure, and ③ the damping effectiveness of the damping material installed inside the speaker enclosure.

A British speaker manufacturer produces speakers where each enclosure is formed into an exponential shape, completely damping 100% of the sound waves radiated inside the enclosure. Although the Japanese retail price is extremely high, these speakers deliver exceptionally high sound quality with no influence from reflected waves within the enclosure.

I challenged myself to develop a speaker enclosure that looks like a conventional box-type speaker, costs the same or less than conventional designs, and can 100% dampen sound waves radiated inside the enclosure. The result is the CRSS (Concave Reflection Speaker System).

Inside the CRSS (Cross) speaker enclosure, sound waves emitted are converted 100% into sound pressure by a concave reflector and a pair of EXP-curve shaped plates, completely eliminating the sound waves.

The CRSS speaker completely silences all sound waves radiated internally. This eliminates any reflected waves from within the speaker enclosure, resulting in extremely low distortion and high sound quality, accurately reproducing the stereo image of the music.
