User manual ELECTRO-VOICE ARISTOCRAT III DATASHEET

[. . . ] Figure 7 illustrates the total directivity of the SL12-2V. The directivity factor Rq(Q) is the relative value, at a point, of an ideal spherical response. Power Handling Electro-Voice components and systems are manufactured to exacting standards, ensuring they will hold up, not only through the most rigorous of power tests, but also through continued use in arduous, reallife conditions. The EIA Loudspeaker Power Rating Full Range (EIA RS-426-A 1980) uses a noise spectrum which mimics typical music and test the thermal and mechanical capabilities of the components. [. . . ] Electro-Voice will support relevant additional standards as and when they become available. Extreme, in-house power test, which push the performance boundaries of the system, are also performed and passed to ensure years of trouble-free service. Specifically, the SL12-2V passes EIA RS426-A 1980 with the following values. RSR= (1. 15 x RE ohms) , RE = 7. 1 ohms PE(MAX) =200 watts Test voltage = square root of PE(MAX) x RSR = 40. 4 volts rms. = 80. 8 volts peak The "peak power-handling capacity of a woofer is determined by the peak test voltage amount. For the SL12-2V, a 80. 8-volt peak test voltage translates into an 800watt short-term-peak power-handling capacity. This is the equivalent of four times the "average" power-handling capacity, ______________________ 1 THX® is a registered trademark of Lucasfilm Ltd. SL12-2V High-Output, T wo- ay Slant Surround Speaker System W and is a peak that can be sustained for only a few milliseconds. However, this sort of short duration peak is very typical in speech and music. Provided the amplifier can reproduce the signal accurately, without clipping, the system will also perform accurately and reliability, even at these levels. Use in Cinemas The SL12-2V has features which make it particularly suitable for use as a cinema surround sound, a black vinyl appearance to complement most theaters interiors. The high dynamics and power handling offered by professional-grade components make it especially suitable for digital surround sound.
