MODEL PR-40 AND QR-40 SPECIFICATIONS (Continued)
The QR-40 is electrically similar to the PR-40 but with its utility type
cabinet is only used where appearance is not a consideration, such as in
tone and reverberation chambers.
The treble direct speaker is normally mounted in the top. In an unusual
installation where the ceiling is very low, or cabinets are stacked or
radiation is otherwise restricted, it is possible to move this speaker to
the hole provided in the front. The metal diffuser in front of the speaker
must also be moved, and the wooden cover must be attached under the top to
close the hole.
