Design
The CS-E700 is a three-way design with a multi-cell horn tweeter for high-frequency clarity and wide dispersion. The 30 cm cone-type woofer has an FB cone made by a unique manufacturing method, plus a large ferrite magnet with a loose design to enhance low-frequency response. The 12 cm midrange unit also has an FB cone and ferrite magnet. Its rear is sealed to block back pressure from the woofer. The front baffle carries a level control, and the enclosure is hermetically sealed with a walnut oil finish. A multi-amplifier terminal on the rear switches between 2-way and 3-way active operation.
