8" 50W coaxial loudspeaker #IMC8A-TS32-1W
ships ready for installation
features 8" 50W coaxial driver & 70V 32W transformer
features. . . . . . . . . . . . .
Includes:
• 8 inch coaxial driver
• 70V 32W transformer
• Steel enclosure (1.25 cu.ft.)
w/forged eyebolts
• White grille
with global

components
• Description: Ready-to-install high performance
loudspeaker for suspended installations
provides quality sound distribution of
foreground or background music in all kinds of
commercial venues—it's ideal for high ceiling/
high energy applications like clubs and bars,
sporting facilities, concourses, hotel ballrooms,
transportation terminals, convention centers,
and exhibit halls.
• Driver (#8A50):
– 8" 50W driver features a 20 oz. LF magnet
with 1.4" copper voice coil to drive a
polyproylene cone with half-roll rubber
surround for long cone travel and good edge
damping. A post-mounted tweeter is a 1"
balanced-drive dome protected by Ferrouid
and a rst-order high-pass lter.
– See the spec sheet for driver #8A50 for more
information.
• Transformer (#TLS-3270):
– 70V 32W transformer for superior music
fidelity in 70V distributed applications has a
screwdriver-adjustable tap selector switch
accessible through an opening in the grille.
– Part of Lowell's 20/20 AudioVision™ line,
the transformer offers true 20Hz-20kHz
performance with full frequency response
and high power handling to allow the speaker
to operate at full potential while providing a
stable load to the amplier. The transformer
allows a distributed speaker system to sound
imperceptibly the same as a transformerless
direct-to-voice-coil system but with easier
wiring, reduced labor, and less expense.
• Enclosure:
–
The 1.25 cu.ft. precision-formed U.S.
steel cylindrical enclosure (19" x 12" dia.)
features a white powder epoxy nish and
1-1/2" thick premium acoustic lining.
– 1/4"–20 forged eyebolts are screwed
into mounting nuts for secure suspended
installation (yware by others).
– Externally accessible connections are
terminated through a 4" x 4" ush cover
plate.
• Grille:
– Perforated steel grille with white powder
epoxy nish (≈ 11.8" dia.)
