An E-series bookshelf speaker system designed by Phil Jones.

It is equipped with two 11.4 cm cone woofers.
This unit is aad custom-made unit. It uses a special high-tech corn material with a special molecular structure in which aluminum and polypropylene are mixed.

The 2.5cm soft dome tweeter is carried.
The silk diaphragm is adopted as a diaphragm. In addition, a chamber with acoustic damping is provided at the back, and by combining this with the pole piece, the frequency response of the tweeter is made smoother.

Magnetic shield design.

The network uses closely matched parts with minimal error.
By using an air core coil for the inductor, even if the playback volume is high, the magnetic saturation that leads to distortion and leakage of the amplifier output is prevented. Also, the printed circuit board is plated with 24 carat gold and has a high current specification.

We adopt virtual coaxial layout for placement of unit.
The enclosure uses a 15 mm thick MDF. It is also made using a wood cutter specially designed for speaker cabinet manufacture. A large amount of vibration absorbing material is used inside the cabinet to contribute to the sound with transparency.
The color of the appearance is maple.

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