Typical 4 way monitor speaker system.

2231A which is a 38cm cone type Woofer low-pass,On inside low-pass, 2405 of a horn type tweeter is adopted as the acoustic lens 2308, an exponential horn 2307, the driver unit 2420, and a high region at 2121 and the mid-high range which are 25cm cone type Woofers.

A two-channel multi-amplifier drive [ in / by the switchover by a backplane switchpoint besides the drive by a built-in network / 300Hz ] is possible. In this case (at the time of a stereo using) the channel divider 5234 and the filter substrate 52-5140 (two sheets) are required.
Moreover, in order to acquire the optimal voice source, exchange of a tweeter is possible when using by vertical placement. When using by horizontal placement, 90 degrees of baffle boards which mounted units other than a Woofer can be rotated.

The blue grill was attached to 4343WX of a black grill and walnut finish 4343 of gray finish.
