Commentary

A compact speaker system that uses orthodox techniques to improve bass reproduction.

It uses a 16 cm cone type woofer that uses a new material, graphite composite cone for the low range.
Graphite composite cone is made by injection molding polypropylene and graphite, and has excellent characteristics such as light weight, high rigidity and high internal loss.
In addition, the actual condition of the vibration mode is analyzed by the modal analysis of the cone shape, and the shape with high composition such as thickening of the cone center is designed, and the low division vibration in the middle and low range is proposed.

A 2.5 cm dome type tweeter is used for the high range.
We have succeeded in reducing the size of the magnetic circuit by using a compact neodymium magnet with high magnetic flux density.
This allows the tweeter and woofer to be positioned close to each other and closer to a point sound source.

Each unit uses Pioneer's own midship mount to prevent unwanted vibrations from being transmitted to the baffle.
This reduces unwanted vibrations affecting the baffle and also reduces the interaction between the woofer and the tweeter through the baffle.

The enclosure uses particle board as a material, and a bass reflex duct is installed on the front to increase the freedom of setting and to obtain a voluminous bass.
Rubber material is used for the duct so as not to generate excessive noise, and in addition, vacuum press molding realizes 8-face round corner.
The body color is modish oak, and the salannet is flat-surfaced with the baffle surface for a clean design.
In addition, the sound quality is tuned with the sarannet installed, so that it can be enjoyed in its original form.

The speaker terminal is gold-plated.
