SST-1
Commentary

This speaker system consists of SST-1, which adopts twin load horn system, and SST-40WT power drive unit.

The SST-1 adopts a twin load horn system in which two horns of different lengths are folded compactly, further improving the high-efficiency and low-distortion reproduction capability of horn speakers.

A unique brilliant throat has been adopted to prevent the sound from the horn and the sound from the front of the speaker from being attenuated in opposite phases, and it is also effective as an acoustic filter.

A 14 cm cone woofer with a chitin-reinforced pulp diaphragm is installed in the low range, and a 5 cm horn type tweeter is installed in the high range.

SST-1 has 3 color variations, metallic black, pearl silver, and metallic red.

The SST-40WT is a power drive unit developed exclusively for the SST-1 and equipped with a unique loudness circuit.

Comes with a separate stand.
Also, there was a special stand for coupling L and R separately sold.
