Commentary
An AV compatible 3-way speaker system that uses TMD (Technics Monocoque Diaphragm).
TMD (Technics Monocoque Diagram) is used for the diaphragm structure of low and middle range.
The TMD was designed by repeating several hundred simulations and prototypes using computer vibration analysis developed by NASA. In this structure, the cone part and center cap part, which were separate pieces in the conventional cone type, are integrated. In addition, by adopting a unique shape selected from computer simulation, the rigidity is dramatically improved. As a result, coupled with the joint drive by the coupling cone, the piston motion range is expanded to twice that of the conventional cone type.
It has a 23 cm cone woofer in the low range and a 10 cm cone midrange in the middle range.
A 2.8 cm flat type tweeter using a honeycomb flat diaphragm is mounted in the high frequency range.
