Commentary
A non-directional horn type tweeter developed by Pioneer.
A special alloy resin of light mass and high stiffness is used for the diaphragm, and an aluminum wire is used for the voice coil to improve acoustic characteristics.
The horn and nozzle fittings are made of aluminum die-cast with a DKA mold and finished by precision machining.
