ELECTRO-VOICE Eliminator i E 15" 2-way, Full range, 99dB, 350W ELECTRO-VOICE Eliminator i E Speakers,Eliminator i General Product Description The Electro-Voice Eliminator i is a high-peak output, high-efficiency two-way stage system. The 15-in. low-frequency/horn-loaded constant-directivity high-frequency system incorporates elements of Ring-Mode Decoupling (RMDTM). RMD techniques substantially improve vocal fundamental intelligibility and produce an up front tonality capable of cutting through even difficult acoustic environments. The Eliminator i enclosure has a unique design that presents a very minimal frontal cross section while still maintaining substantial internal volume. A newly developed handle concept allows for extremely comfortable transportation from any orientation. The design is light weight, but very rugged and features a heavy metal grille and highly stylized corner protection. The heart of Eliminator i's high performance design is the combination of a high-excursion low-frequency suspension system with Electro-Voice's unique Ring-Mode Decoupling. All loudspeaker drivers exhibit mechanical resonance modes that add their own time-domain or ringing-mode colorations. These colorations limit and reduce overall system intelligibility. The Eliminator i uses RMD to control several fundamental mechanical ringing modes. The result is substantially improved vocal range intelligibility and system openness. When extended low-frequency operation is required, the performance can be further enhanced with the use of the Eliminator i Sub, which can be used in either biamp or full-range passive mode. Vented enclosures offer excellent power handling and low distortion in the lowest octave of rated operation. However, it is always advisable to filter material below enclosure tuning to further improve system output and headroom. The Eliminator i should be high-pass filtered to reduce subsonic material below 40 Hz.

Power-Handling Capacity 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, real-life conditions. The EIA Loudspeaker Power Rating Full Range (ANSI/EIA RS-426-A 1980) uses a noise spectrum that mimics typical music and tests 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 tests, which push the performance boundaries of the woofers, are also performed and passed to ensure years of trouble-free service. Specifically, the Eliminator i passes ANSI/ EIA RS-426-A 1980 with the following values: RSR = 5.175 ohms (1.15 x RE) PE(MAX) = 350 watts Test voltage = 42.55 volts rms, 85.10 volts peak (+6 dB) The peak power-handling capacity of a woofer is determined by the peak test voltage amount. For the Eliminator i a 85.10-voltpeak- test voltage translates into 1,400-watts short-term peak powerhandling capacity. This is the equivalent of four times the average power-handling capacity, 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 woofer will also perform accurately and reliably, even at these levels.
Amplifier Recommendations The power-handling rating of the Eliminator i is 350-watts continuous. The specific tests used employ a crest factor (ratio of peak energy to continuous energy of at least 6 dB). During extended testing, the Eliminator i is routinely subjected to peak levels far in excess of its continuous rating of 350 watts. Many amplifier designs are capable of producing peak power levels in excess of their ratings as well, so exact pairing of loudspeaker rating and amplifier ratings is not necessary. Amplifier continuous ratings of 250 watts to 400 watts are suggested. Larger amplifier ratings are recommended for maximum dynamic range, but it should be recommended that amplifier continuous levels (as opposed to peak levels) be within the range quoted for the Eliminator i long-term average power-handling rating.
]Stand Mounting The Eliminator i is equipped with an internal stand-mount adapter that will accommodate standard 1 3/8-in. diameter speaker stands.
General Product DescriptionThe Electro-Voice Eliminator i Sub is a single 18 inch subwoofersystem designed to produce very high-peak output musical material.The Eliminator i Sub can be used either in conventional biamplifiedoperation or in full-range passive mode with the Eliminator itwo-way high-peak output stage system in parallel. When used inparallel, the combined impedance is 4 ohms. The internal passivecrossover consists of low-pass filter to the 18-in. DL18BFH.The system is designed for operation up to 100 Hz (in passivemode). The system can also be used in biamp mode by using anactive crossover system with slopes of 24 dB per-octave.Recommended crossover point is 80 Hz when used with aloudspeaker processor/crossover capable of low frequencyprotection; or, as this is a vented system, a 40 Hz low frequencyfilter of at least 3rd or 4th order is recommended (18 dB/ octave to24 dB/octave) to filter out signals below that frequency.The Eliminator i Sub includes a top-mounted stand adapter andan 18 in. pole mount for use with the Eliminator i full-range system.Safety concerns limit the use of a pole greater than 18 inches inlength (under no circumstances should a pole of greater than 18inches be used with the Eliminator i Sub). The DL18BFH wooferwill provide average power handling ratings of 400 watts EIA andpeak power ratings of 800 to 1000 watts. The system inputconnections are 1/4-in. phone. Vented enclosures offer excellentpower handling and low distortion in the lowest octave of ratedoperation. However, it is always advisable to filter material belowenclosure tuning to further improve system output and headroom.The Eliminator i should be high-pass filtered to reduce subsonicmaterial below 40 Hz.
Power handling To our knowledge, Electro-Voice was the first U.S. manufacturer todevelop and publish a power test closely related to real-lifeconditions. First, we use a random-noise input signal because itcontains many frequencies simultaneously, just like real voice orinstrument program. Second, our signal contains more energy atextremely high and low frequencies than typical actual program,adding an extra measure of reliability. Third, the test signal includesnot only the overall long term average or continuous level-whichour ears interpret as loudness-but also short-duration peaks whichare many times higher than the average, just like actual program.The long-term average level stresses the speaker thermally (heat).The instantaneous peaks test mechanical reliability (cone anddiaphragm excursion). Note that the sine wave test signalssometimes used have a much less demanding peak value relativeto their average level. In actual use, long-term average levels existfrom several seconds on up, but we apply the long-term averagefor several hours, adding another extra measure of reliability.Specifically, the Eliminator i Sub is designed to withstand thepower test described in the ANSI/EIA RS-426-A 1980. The EIA testspectrum is applied for eight hours. To obtain the spectrum, theoutput of a white-noise generator (white noise is a particular typeof random noise with equal energy per bandwidth in Hz) is fed to ashaping filter with 6-dB-per-octave slopes below 40 Hz and above318 Hz..When measured with the usual constant-percentage bandwidthanalyzer (one-third-octave), this shaping filter produces a spectrumwhose 3-dB-down points are at 100 Hz and 1,200 Hz with a3-dB-per-octave slope above 1,200 Hz.
Architects' and Engineers' SpecificationsThe loudspeaker system shall be a subwoofer system consistingof one 45.7-cm (18-in.) low-frequency transducer in a vented quasiband pass design. The system shall be capable of either biampoperation or full-range passive (when used with the Eliminator istage system or other appropriate full-range system). The passivemode shall provide first order low-pass filtering. The system shallhave a rated frequency response of 40 Hz to 100 Hz (passive mode)and is capable of extended high-level operation within that range.Power handling (long-term average) shall be 400 watts when EIARS-426-A 1980 is employed as a test method or 500 watts whenAES 1984 is used at the test method. The system sensitivity shallbe 98 dB (101 dB with 1/2 space load-common orientation) with a1 watt input at a distance of 1 meter. The nominal impedance shallbe 8 ohms and shall produce a combined impedance of 4 ohmswhen used with the Eliminator i, full-range system. Inputconnections shall be 1/4-in. phone input and output .The system dimensions shall be 85.4 cm (33 5/8 in.) high by 42.9cm wide (16.9 in.) and 60.9 cm (24 in.) deep and have a net weightof 87 lb.
Amplifier RecommendationThe power handling of the Eliminator i Sub is 400 watts EIA (500watts AES). The specific tests used employ a crest factor (ratio ofpeak energy to continuous energy) of at least 6 dB. During extendedtesting the loudspeaker in the Eliminator i Sub is routinelysubjected to peak levels far in excess of the published continuousrating. Many amplifier designs are capable of producing peak powerlevels in excess of their ratings as well so exact pairings ofloudspeaker power handling ratings and amplifier ratings are notnecessary. Amplifier continuous ratings of 400 watts to 800 wattsare recommended for use with the Eliminator i Sub. Larger amplifierratings may be used for maximum dynamic range but it should beremembered that amplifier continuous levels (as opposed to peaklevels) be within the range quoted for the Eliminator i Sub long-termaverage power handling.

When measured with the usual constantpercentagebandwidth analyzer (one-third-octave), this shaping filterproduces a spectrum whose 3-dB-down points are at 100 Hz and 1,200 Hzwith a 3-dB-per-octave slope above 1,200 Hz.

Many amplifier designs are capable of producing peakpower levels in excess of their ratings as well, so exact pairing ofloudspeaker rating and amplifier ratings is not necessary. Amplifiercontinuous ratings of 300 watts to 600 watts into 4 ohms are suggested.
