Description
 
The large-sized studio monitor speaker system of four ways.

2231A which is a 38cm cone type Woofer is adopted as low-pass at the 30cm cone type 2202A and a mid-high range two pieces and inside low-pass, and 2405 of a horn type tweeter is adopted as the acoustic lens 2308, an exponential horn 2311, a driver 2440, and a super-high region.

The network has adopted the two-channel multi-amplifier drive in the cross over frequency of 250Hz.
In this case, the optional channel divider 5234 and the filter substrate 52-5121 (at the time of a stereo using two sheets) are required.
Other bands are driven in the built-in network.

Level adjustment is possible for the horn tweeter for super-high regions at the volume type Attenuator of the front panel.

In order to obtain the optimal voice-source location, tweeter honed Leiber's right-and-left exchange is possible.
Moreover, it can also hang to reverse by iron reinforcement metal fittings.

The blue grill was attached to 4350WXA of walnut finish of a black grill at 4350A of the gray enclosure.
