An all-horn speaker system developed as a speaker that reproduces the natural sound, depth of sound, and subtle nuances of tone.
30 cm woofer system EW-302 is used for the low range.
The use of the front loaded horn gives the sound of the horn system, and the thickness of the middle and low band is improved by the synergistic effect with the bass reflex system.
Also, EW-302 has a built-in network for 2-way H and F.
Driver ED-911 and horn EH-321L are adopted for middle and high range.
The ED-911 pursues high efficiency and wide range. It exhibits excellent characteristics in the extension of sound pitch by the adoption of 3 slit phasing plug, aluminum alloy diaphragm with tangential edge, voice coil with aluminum edgewise wire, and rear type compression system.
The EH 321 l is a wooden horn made of Painted maple plywood. It has less horn noise than metallic horns, so it realizes a natural sound.
The model2301 is usually 2-way model configuration, but there was a variation that combined ET-701 for super high frequency.
The ET 701 is a rear compression type with an emphasis on natural sound.
