Commentary
Based on the ideal of a speaker that lets you forget the existence of audio equipment and become enchanted with the music itself, this is a floor-type speaker system that keeps the basics faithfully and improves the perfection of each unit while maintaining the overall balance.
EL 403, a 40 cm cone type woofer, is used for the low range.
Newly developed cone paper is used for the diaphragm, and low-frequency distortion is reduced by high-performance low-distortion magnetic circuit using Alnico magnet.
Driver unit ED-915 and horn EH-351S are adopted for middle and high range.
The ED 915 uses an ultra-lightweight beryllium diaphragm with a diameter of 48 mm, but achieves high-frequency playback at 22 kHz. The fading plug uses a triple slit type combined with ultra-precision machining to improve transient characteristics. The magnet uses an alnico magnet.
The Wood Secoral Horn EH-351S consists of a first horn of precision aluminum casting and a second horn of wood made of birch plywood.
A horn type super tweeter, ET 703, is used for the super high band.
The combination of a 35 mm diameter beryllium diaphragm and a high-flux magnetic circuit with a rare-earth magnet realizes high-frequency reproduction at 45 kHz.
The horn section is a diffuse type with wide directivity.
EN 907 is used for the network part.
It is designed to withstand a maximum input power of 300W, and has improved sound quality by using low distortion and low DC resistance for the coil and metalized film type for the condenser.
The panel is equipped with an easy-to-use multi-amplifier terminal.
