B. CURVED SCREEN
The best possible acoustical loading of the system
to the room is obtained when the loudspeakers are
mounted in a large flat baffle, as shown in Figure 10.
Here,
the 4675A-2 system has been specified for extra
acoustical power output in the 40 Hz to 500 Hz range.
The baffle should not be interrupted, and it should
extend the entire width of the loudspeaker array.
Mechanical details of this baffle are given in Figure 11.
Ideally the baffle should be continuous in a multi-loud-
speaker screen array.
