LOUDSPEAKER
The Sound Advance®CT8 is a unique, extended bandwidth, wide-dispersion pla-
nar loudspeaker designed for use in commercial installations.
Patented Planar Diaphragm Technology™ allows a CT8 that has been properly
installed in a ceiling or wall boundary to radiate sound in a 140° hemispherical
pattern with smooth, even coverage. This dispersion characteristic allows CT8
speakers to be spaced farther apart than narrow-dispersion conventional speakers,
reducing the total quantity of loudspeakers required in almost any installation.
The CT8 is generally mounted into wood or metal stud walls and ceilings or
suspended ceiling tile systems, and will retrofit into almost all existing standard
8” diameter speaker openings. Mounting is standard screw-type, and optional tile
bridge and backcan mounting accessories are available. An optional enclosure
compensation module is also available, to restore bass performance when the CT8
is installed in a backcan.
The flat Expanded Polystyrene®[EPS] loudspeaker surface may be finished with
water soluble materials such as latex paints to match almost any decor or color
requirement using conventional brush-on, roller or airless spray application
systems.
The CT8 is transformer-coupled, with the following taps: 0.5W, 1W, 2W, 4W, 8W,
16W, and 8-ohm bypass.
Warranty:
Sound Advance®warrantees the CT8 to be free of any defect in material of work-
manship for a period of 5 years from the date of purchase. During the warranty
period, Sound Advance will repair or replace (at its option) all such defects without
charge for parts or labor, if returned prepaid to the proper Sound Advance service
facility, together with the original sales receipt or other proof of purchase. The unit
will be returned prepaid.
