The K series tone cabinet are designed for use in all types of installations: church, home, school, and entertainment places. Their response is non-directional, with high frequencies projected vertically and the low frequencies horizontal, although provisions exist for installing the treble speakers to project horizontally where vertical projection might be obstructed.
The tone cabinet contains separate amplifier sections for treble and bass response with cross-over point at 200 cycles.
Amplifiers are not interchangeable with amplifiers in other model tone cabinets.
