Theatre Sound System®
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-gen- eration 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-fre- quency effects. For low frequencies, two 15inch woofers are vertically stacked in a di- rect-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 highand low-frequency reproduction has proven to be an excellent choice for small to medium sized houses.
The TS940D incorporates a number of in- staller-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-fre- quency section. All pre-drilled holes are T- nut 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-fre- quency 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.
