Commentary

This is a 2-way coaxial type unit that uses a dome tweeter for the treble part.

A 20 cm cone type woofer is used for the low range, and a dome type tweeter using titanium diaphragm is used for the high range.

Interference between the tweeter and woofer is suppressed by a spherical baffle placed around the domed tweeter.

EPT edge is used for the edge of the woofer to reduce distortion.
