Broadband Sound Concept:
Mid-low, medium and treble frequencies go through full range double speaker system with linear characteristic, giving sound source so desired cohesion and neutrality. In practice this provides a precise and spatially-arranged musical spectrum.

Double Loudspeaker Concept:
In the KETSUS instrument power is distributed into two woofers โ€“ the main effect being two times higher output & reduced distortions.

The box in Ketsus is a multiple-reinforced casing, featuring a diagonal inner partition to prevent unnecessary acoustic reverberations. The fullrange speaker and woofer units have been adapted for separate encloasures: closed and bass-reflex type.

The cabinet structure is bulid from 20mm to 40mm panels with strong internal bracings. Additionally different wall connecting system for front and rear panels has been developed to minimize the box resonances. In KETSUS perfect damping process goes into four ways : wool blocks, bitumen mats, pyramid foam and low density damping material.
