Hammond Model QR-40

(In production February 1959 to ???)

Equipped with two 15″ speakers for bass tones and two 12″ speakers for the treble tones. They provide three dimension amplification which creates a beautiful reverberation effect in stereo. These cabinets feature the new and improved Hammond reverberation control for both bass and treble tones.  Convenient outside controls make it easy to change the degree of reverberation for each.

The QR-40 is electrically similar to the PR-40 but with utility type cabinet is only used where appearance is not a consideration such as tone and reverberation chambers.

The treble direct speaker is normally mounted in the top. In unusual installations 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.
