Commentary
A two way speaker system that uses a sandwich cone.
A 17 cm cone type woofer is used for the low range.
For the cone, we have adopted a sandwich cone made by sandwiching thin polystyrene cone with uniformly stretched aluminum foil.
In addition, it uses a low distortion suspension and a long slow magnet that withstands large amplitude to ensure stable playback even at large input.
A 3 cm cone type tweeter is used for the high range.
The cone is made of plastic, and by winding a coil directly around the neck of the cone, strain is kept low.
The network uses a filter of 18cm/oct. with an emphasis on phase characteristics in the mid-range.
