System Features
• Ultra Compact Package and horizontal
configuration have been optimized from the
start for use with subwoofer, enabling easy
and unobtrusive installation.
• Outstanding Sonic Accuracy, on and off axis
as a result of advanced direct radiating design for
an exceptionally natural sound character.
• Wide Coverage of 130 degrees is
maintained over its entire operating range for
great sound to every seat in the house.
• Advanced Crossover Network provides
asymmetrical slopes to equalize driver's
frequency and phase response at crossover.
• Revolutionary RCF TW116 Hard Dome
Driver for HiFi type sound with exceptional
high frequency bandwidth.
Applications
The DS123B is designed for use in
conjunction with a subwoofer system, in high
level club playback and cabaret reinforcement
systems or any nearfield application where flat
response and wide coverage are required at high
sound pressure levels. Its physical construction
and packaging have been optimized for easy
permanent installation. The DS123B's horizontal
configuration permits unobtrusive hanging
around the corners of a dance floor or above the
perimeter of the stage.
Description
The DS123B is a three-way system utilizing
all direct radiating drivers with wide coverage
over the 100 to 20,000 Hz band. It boasts
exceptionally flat power response due to the
seamless integration of the three drivers by a
complex Forsythe designed crossover network
featuring asymmetrically sloped filters for
frequency and phase equalization.
The low frequency section consists of an RCF
L12/584 high efficiency driver mounted in a
compact enclosure. The vent tuning is optimized
for flat response and maximum output above 100
Hz. When used for all music reproduction
applications, the DS123B is intended to work
with a subwoofer system such as the EAW VB1
18 18 inch or VB215 dual 15 inch vented low
frequency systems.
Mid frequencies are provided by a "state of
the art" EAW MF170A 170mm (6.5-in) driver. It
inherently offers more extended power
response than any 8 or 10 inch driver, and its
advanced poly-laminated cone enables lower
distortion at high sound pressure levels than is
possible with a compression driver.
RCF's advanced TW1 16 hard dome high
frequency driver combines the open natural sound
character like a HiFi soft dome with the output
levels demanded in a high level professional
system. This unique driver allows the DS123B to
offer higher definition and smoother sound than
all other systems of equal output capabilities
which use compression drivers for the higher
frequencies.
