Commentary
Standard 30 cm diameter cone type woofer unit.
It is designed so that even a cabinet with relatively small inner volume can make blooming sound.
In addition, as a large-diameter woofer, the high-frequency reproduction limit is high, and the crossover is possible even at around 2 kHz to 3 kHz.
Aluminum die-cast is used for the frame part.
