Features

A small bookshelf speaker system from E series designed by Phil Jones.

The 11.4cm corn woofer is carried for low range.
This unit is aad custom-made unit. The diaphragm uses a special high-tech cone material with a special molecular structure in which aluminum and polypropylene are mixed.

The 2.5cm soft dome shape tweeter is carried for high range.
This unit uses a silk diaphragm.
Also, there is a chamber with acoustic damping behind the unit. And this is taken as the structure combined with the pole piece. This makes the tweeter's Frequency Response smoother.

This speaker is magnetically shielded.

The network uses closely matched parts with minimal error.
Moreover, the air core coil is used for the inductor. This prevents magnetic saturation even when the playback volume is high, and prevents distortion and leakage of the amplifier output.
The printed circuit board is plated with 24 carat gold. It is a high current specification.

The enclosure uses a 15 mm thick MDF material. Made using a wood cutter specially designed for speaker cabinet manufacture.
In addition, a large amount of vibration absorbing material is used inside the cabinet. This contributes to the sound with transparency.
Appearance color is maple.

It seems that there were two types of specifications on the grille fixed part.

Speaker stand and Wall bracket were sold as an option.
