Commentary
Horn type super tweeter.
Newly developed round thick horns and equalizers made by precision machining of aluminum light alloy are used.
Because the aperture size of the horn is small, it shows excellent directional characteristics up to high frequencies.
A ring diaphragm made of ultra-lightweight hard aluminum alloy is used for the diaphragm.
Alnico magnet is used for the magnetic circuit.
Includes a tweeter base.
