K.C.S. S-1800 and S-1801 extra-flat speaker systems are specially designed for the screen channel in small/medium size cinema theatres where there is very little space between projection screen and rear wall.
This speaker system features a bass cabinet fitted with one 15" Ø speaker, and a high-frequency unit fitted with a compression driver with 2" Ø titanium membrane and 1" Ø mouth. Its 90 x 90 constant dispersion horn provides an exeptionally uniform coverage in the auditorium from first to last row.
S-1800 (passive) speaker system has a passive crossover with cut frequency at 900 Hz, while S-1801 (bi-amplified) is designed to operate with external active crossover with cut frequency at 1000 Hz.
