LOUDSPEAKER SYSTEM
DESCRIPTION
Designed to meet professional musician stand­
ards, the rugged 1234 Wide-Range speaker sys­
tem contains components selected for high
efficiency, high power handling and reliable
performance.
The overall performance of the 1234 satisfies the
most demanding requirements of clubs, audi­
toriums, ballrooms and most large environments
where only loud, undistorted, and quality sound
will do. High power handling (up to 120 watts)
and low distortion have been achieved with
a new 15" musical instrument speaker yielding
excellent bass and mid-bass, and by designing
the high-frequency-extending Tangerine^'^ radial
phase plug’in the 808-8B driver. A cast-alumi­
num sectoral horn is coupled to the compression
driver for maximum dispersion control and the
dividing network provides smooth crossover at
1200 Hz. for protection of the driver and im­
proved system power-handling.
Built to be used under physically demanding cir­
cumstances, the portable 1234 features a dur­
able yet elegant bass reflex enclosure. Steel front
legs, rear casters and a tow bar make handling
an easy task, while vinyl edge bumper guards
protect the cabinet from abuse.
The sturdy wood enclosure is constructed of
3 / 4 " plywood and particle board, contains acous­
tical damping materials, and is solidly braced to
effect the optimum in performance character­
istics selected for the 1234 system.
