Commentary
This is a four way closed-type speaker system using a Septor series unit.
A 30 cm cone type woofer W-30AmkII is mounted in the low range.
The unit uses parts such as butterfly dampers and foam rubber edges made from epoxy fiberglass laminates, Finnish pulp corn paper, and edgewise wound voice coils.
A horn type squaker HM-500AmkII is mounted in the middle range, and a horn type tweeter TW-8AmkII and an acoustic lens AL-8A are mounted in the high range.
In addition, the TW-7SmkII horn type super tweeter is installed for ultra-high frequency, enabling ultra-high frequency reproduction up to 40 kHz.
The enclosure is a fully enclosed low-boy type enclosure with an internal volume of 120L. The front baffle is slanted to allow for listening.
In addition, it is 40 mm thick and reinforced well to prevent box rumbling.
The enclosure is hermetically sealed.
Equipped with a multi-amplifier terminal, multi-amplifier playback is possible by switching the switch.
