User manual ELECTRO-VOICE ELIMINATOR I SUB EDS

[. . . ] The internal passive crossover consists of low-pass filter to the 18-in. The system can also be used in biamp mode by using an active crossover system with slopes of 24 dB per-octave. [. . . ] First, we use a random-noise input signal because it contains many frequencies simultaneously, just like real voice or instrument program. Second, our signal contains more energy at extremely high and low frequencies than typical actual program, adding an extra measure of reliability. Third, the test signal includes not only the overall "long term average" or "continuous" level­which our ears interpret as loudness­but also short-duration peaks which are many times higher than the average, just like actual program. The instantaneous peaks test mechanical reliability (cone and diaphragm excursion). Note that the sine wave test signals sometimes used have a much less demanding peak value relative to their average level. In actual use, long-term average levels exist from several seconds on up, but we apply the long-term average for several hours, adding another extra measure of reliability. Specifically, the Eliminator iTM Sub is designed to withstand the power test described in the ANSI/EIA RS-426-A 1980. To obtain the spectrum, the Amplifier Recommendation The power handling of the Eliminator iTM Sub is 400 watts EIA (500 watts AES). The specific tests used employ a crest factor (ratio of peak energy to continuous energy) of at least 6 dB. During extended testing the loudspeaker in the Eliminator iTM Sub is routinely subjected to peak levels far in excess of the published continuous rating. Many amplifier designs are capable of producing peak power levels in excess of their ratings as well so exact "pairings" of loudspeaker power handling ratings and amplifier ratings are not necessary. Amplifier continuous ratings of 400 watts to 800 watts are recommended for use with the Eliminator iTM Sub. Larger amplifier ratings may be used for maximum dynamic range but it should be remembered that amplifier continuous levels (as opposed to peak levels) be within the range quoted for the Eliminator iTM Sub long-term average power handling.
