Commentary
A speaker system using the same unit as the AR-10 Π.
A 30.5 cm cone type woofer is installed in the low range.
The mid-range is equipped with a 3.8 cm domed scoker and the high-range is equipped with a 1.9 cm domed tweeter.
The enclosure uses a traditional acoustic suspension system that improves bass playback by allowing the air inside the fully enclosed enclosure to act as a spring to support the cones.
