Commentary

This is a speaker system that pursues high purity with a space-friendly style.

For the low range, it uses 18 cm cone type woofer made of bio black cone, for the middle range, it uses 12 cm bio uses 12 cm Bio-Cloth Corns Coker. By using the same material, the connection is improved.
In addition, M. D. C. T. (magnetic distortion reduction technology) has been introduced, and harmonic distortion is suppressed by adopting an aluminum ring inside the magnet to cancel the effect of DC leakage magnetic flux.

A 2.5 cm soft dome type tweeter with polyester fiber base coated with special material is adopted for the high range.

The network division divides the circuit and parts of the unit, and realizes a network with no mutual interference and less distortion.

An acoustic stabilizer is attached to the under plate of the woofer to reduce unnecessary vibration.
