Description

The Electro-Voice Eliminator ™ Double is ahigh-peak output, high-efficiency two-waystage system. The dual 15 in. low-fre-quency/horn-loaded constant-directivity

high-frequency system incorporates ele-ments of Ring-Mode Decoupling(RMD™). RMD™ techniques substan-tially improve vocal fundamental intelligi-bility and produce an “up front” tonalitycapable of cutting through even difficultacoustic environments.

The Eliminator ™ Double enclosure has aunique design that presents a very mini-mal frontal cross section while still main-taining substantial internal volume. Thetop and bottom woofers are isolated from

each other to prevent any negative inter-action, while a newly developed handleconcept allows for extremely comfortabletransportation from any orientation. Thedesign is light weight, but very rugged andfeatures a heavy metal grill and highly styl-ized corner protection.

The heart of the Eliminator ™ Double's highperformance design is the combination of a high-excursion low-frequency suspen-sion system with Electro-Voice’s uniqueRing-Mode Decoupling. All loudspeaker

drivers exhibit mechanical resonancemodes that add their own time-domain orringing-mode colorations. These colora-tions limit and reduce overall system intel-ligibility. The Eliminator ™ Double's use of RMD™ will control several fundamental

mechanical ringing modes. The result issubstantially improved vocal range intelli-gibility and system “openness”.

Two 15 in. drivers provide very high out-put at the lower frequencies. The low fre-quency drivers are crossed over at differ-ent points to provide a smooth frequencyresponse. When extended high outputlow-frequency operation is required, per-formance can be further enhanced bybiamping the Eliminator ™ Double with theEliminator ™ Sub. Vented enclosures offer

excellent power handling and low distor-tion in the lowest octave of rated opera-tion. It is always advisable however tofilter material below enclosure tuning tofurther improve system output and head-room. The Eliminator ™ Double should behigh-pass filtered to reduce sub sonic ma-terial below 40 Hz.

Power Handling

To our knowledge, Electro-Voice was thefirst U.S. manufacturer to develop and pub-

lish a power test closely related to real-lifeconditions. First, we use a random-noiseinput signal because it contains many fre-quencies simultaneously, just like real voiceor instrument program. Second, our signalcontains more energy at extremely high andlow frequencies than typical actual pro-gram, adding an extra measure of reliabil-ity. Third, the test signal includes not onlythe overall “long term average” or “con-tinuous” level—which our ears interpretas loudness—but also short-durationpeaks which are many times higher thanthe average, just like actual program. Thelong-term average level stresses thespeaker thermally (heat). The instanta-neous peaks test mechanical reliability(cone and diaphragm excursion). Note thatthe sine-wave test signals sometimes usedhave a much less demanding peak valuerelative to their average level. In actual use,long-term average levels exist from severalseconds on up, but we apply the long-termaverage for several hours, adding anotherextra measure of reliability.

Specifically, the Eliminator ™ Double isdesigned to withstand the power testdescribed in the ANSI/EIA RS-426-A1980. The EIA test spectrum is applied foreight hours. To obtain the spectrum, theoutput of a white-noise generator (whitenoise is a particular type of random noise

with equal energy per bandwidth in Hz) isfed to a shaping filter with 6-dB-per-oc-tave slopes below 40 Hz and above 318Hz. When measured with the usual con-stant-percentage bandwidth analyzer(one-third-octave), this shaping filter

produces a spectrum whose 3-dB-downpoints are at 100 Hz and 1,200 Hz with a3-dB-per-octave slope above 1,200 Hz.

Amplifier Recommendations

The power-handling rating of the Elimina-tor ™ Double is 600-watts continuous. Thespecific tests used employ a crest factor(ratio of peak energy to continuous en-ergy) of at least 6 dB. During extendedtesting, the Eliminator ™ Double is routinelysubjected to peak levels far in excess of its

continuous rating of 600 watts. Many am-plifier designs are capable of producingpeak power levels in excess of their ratingsas well, so exact “pairing’ of loudspeakerrating and amplifier ratings is not neces-sary. Amplifier continuous ratings of 300watts to 600 watts into 8 ohms are sug-gested.
