A 2-way speaker system developed as an improved version of the 4320 and 4331.
A 38 cm cone type woofer 2231A is mounted for the low range, and a horn type unit combining an acoustic lens 2308, an exponential horn 2312 and a driver 2420 is mounted for the high range.
In addition to the built-in network drive, the 4331A can be used for 2-channel multi-amp drive by switching the rear switch.
The enclosure uses a bass reflex system.
You can also change the mounting of the acoustic lens so that it can be used in either vertical or horizontal orientation.
It is equipped with iron reinforcing metal fittings and can be suspended.
There are two variations in appearance : the 4331A uses a gray finish and black grill, and the 4331 awx uses a walnut finish and blue grill.
