Control 300 are larger systems than
the Control Contractor 24 and 26 models, with 200
mm (8 in) and 300 mm (12 in) low-frequency drivers,
high-power compression drivers, and higher sound
output capabilities.
Whereas the current Control Contractor
ceiling speaker models are of an "integrated" design
-- with pre-attached backcans -- these large-format
speakers are sold separately from the backcans,
allowing for pre-installation of the backcans.
The main item is the driver assembly pre-mounted
to a baffle, as shown in the picture, below. Accessories,
sold separately, include best-in-class metal back
boxes and contemporary grilles.
