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.
