Commentary
This 3-way bookshelf speaker system is the predecessor of the AR-14.
It has a 25 cm cone woofer in the low range and a 5.6 cm cone midrange in the middle range.
A 1.9 cm dome type tweeter is installed in the high range.
Resistance to input is improved by adopting a liquid cooling system.
As a level control, a 3-stage switching tone control for middle and high frequencies is installed.
The enclosure features 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.
