Description
In the TS940D, Electro-Voice has combined
its expertise in constant-directivity horns,
high-frequency compression drivers and lowfrequency speakers and enclosures to produce
a compact, easily installed theatre stage system with superior performance in all areas:
uniform dispersion to the higheest frequencies, high efficiency , high power capacity and
wide, smooth frequency response.
The TS940D matches the only second-generation constant-directivity high-frequency
horn to a world-class high-frequency driver,
providing accurate reproduction and coverage of frequencies from500 Hz to 20,000 Hz.
Electro-Voice invented constant-direectivity
technology, first introduced in our HR series
horns in 1974. The HP horn is the TS940D is
a significant refinement. Constant directivity means that all frequencies are enenly
spread over the horn's rated coverage angle,
so that every seat in the house can receive
booth clear dialogue and subtle high-frequency effects. For low frequencies, two 15inch woofers are vertically stacked in a direct-radiating configuration, providing a coverage pattern thatlosely matches that of the
high-frequency horn in the crossover region.
Such a match is not possible with more traditional horn-loaded bass enclosure. The high
excursion woofers, mounted in an optimally
vented, Thiele-Small enclosure, provide highimpact bass from 40-500 Hz, at average powers up to 800 watts, when required. In the
field, the TS940D's combination of high- and
low-frequency reproduction has proven to be
an excellent choice for small to medium sized
houses.
The TS940D incorporates a number of installer-recommended features, for quick,
trouble-free and low-cost installation. Among
these features is a dedicated crossover/
equilizer that is easily flush mounted in the
pre-sized, pre-drilled hole located in the side
of the low-frequency enclosure. Side mounting provides easy wiring access when the
system is installed against a wall. Through
the use of the horn mounting kit and predrilled holes in the low-frequency system, the
high-frequency section is easily mounted in
the proper position on top of the low-frequency section. All pre-drilled holes are Tnut loaded, including bass driver mounting
holes. This means quick and easy driver replacement. All components of the TS940D
are finished in matte black, to eliminate any
reflections back through the screen.
Frequency Response
Figure 2 shows TS992-LX frequency response with presets of the Electro-Voice
Dx34A digital speaker system processor (see
Crossover and Basic Equalization section).
The measurement was made with a swept
sine-wave signal, 4 volts at 500 Hz, in an
anechoic (echoless) environment. The microphone was at a distance of 3.0 m (10 ft), on
an axis at the lower edge of the high-frequency horn. Figure 3 shows the frequency
response of the individual sections of the
TS992-LX, measured under the same conditions but with a 4-volt input constant with
frequency, the results of which were then normalized to 1 watt/1 meter.
Frequeny Response
The data was measured in an anechoic
(echoless) environement at 20 feet on axis with
4 volts of swept 1/3-octave random noise. The
frequency response curve for the TS940D is
shown in Figure2.
