Commentary
A multi-amplifier speaker system.
A 30 cm cone type woofer is installed in the low range.
It is a low-fo long travel woofer that pursues the material and shape of diaphragm, edge, damper, etc., and achieves low-distortion low sound reproduction.
The mid-range has a 12 cm cone mid-range.
A horn type tweeter with a Mylar diaphragm is mounted in the high frequency range.
Level control is provided for the middle and high frequencies.
The enclosure is hermetically sealed.
The net grill part uses TEAC's original triple diamond lattice.
This grating has a large grating window, and the tweeter unit layout is placed in the center of the grating to suppress diffraction in the high-frequency range. In addition, the resonance of the grating itself is damped by changing the thickness of the unit composing the grating to prevent the resonance of the grating from adversely affecting the sound quality of the speaker.
