Description
The Electro-Voice Force® Monitor is a high- peak output, high-efficiency super low pro- file two-way floor monitor. The Force® Monitor features a constant directivity 80° x 55° horn in a vertical orientation that pro- vides usable monitor angles of 50° and 65°. The combined professional quality manufactured components arrange in a horizontal array with a very durable and road worthy light weight enclosure. The result is a very high performance system with excellent vocal reproduction and bass response that is surprising from such a small enclosure.
The Force® Monitor enclosure has a unique design that presents a very minimal front cross section along with an exremely low profile. A top mounted strap handle al- lows for comfortable one handed transpor- tation. The design is light weight, but very rugged and features a heavy metal grill and highly stylized corner protection.
The Force® Monitor also features a stand mount adapter on the woofer side for ver- tical orientation (standard 1 3/8 diameter.)
Power-Handling Capacity
Electro-Voice components and systems are manufactured to exacting standards, en- suring 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 which mimics typical music and tests the ther- mal and mechanical capabilities of the components. Electro-Voice will support rel- evant additional standards as and when they become available. Extreme, in-house power tests, which push the performance boundaries of the woofers, are also per- formed and passed to ensure years of trouble-free service.
Specifically, the Eliminator Monitor passes ANSI/EIA RS-426-A 1980 with the follow- ing values:
RSR = 6.55 ohms (1.15 x RE)
PE(MAX) = 150 watts
Test voltage = 31.34 volts rms,
138.00 volts peak (+6dB)
The “peak” power-handling capacity of a woofer is determined by the peak test volt-
age amount. For the Eliminator Monitor, a
138.00-volt-peak-test voltage translates into 600-watts short-term peak power-han- dling capacity. This is the equivalent of four times the “av erage” power-handling capacity, and is a peak that can be sus- tained for only a few milliseconds. How- ever, this sort of short duration peak is very typical in speech and music. Provided the amplifier can reproduce the signal accu- rately, without clipping, the woofer will also perform accurately and reliably, even at these levels.
Amplifier Recommendations
The power-handling rating of the Force® Monitor is 150-watts continuous. The spe- cific tests used employ a crest factor (ratio of peak energy to continuous energy) of at least 6 dB. During extended testing, the Force® Monitor is routinely subjected to peak levels far in excess of its continuous rating of 150 watts. Many amplifier de- signs 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. Ampli- fier continuous ratings of 150 watts to 300 watts into 8 ohms are suggested. Larger amplifier ratings are recommended for maxi-
