Description The Electro-Voice Force Sub is an 8-ohm, dual-15-inch subwoofer system designed to reproduce high impact bass program material from a small, compact, easily portable enclosure. The Force Sub is intended for use with the Electro-Voice Force full-range stage system, and incorporates a built-in lowpass filter to allow parallel operation of both systems from a single amplifier channel. When connected in parallel, the combined impedance is 4 ohms. Conventional biamplified operation is also possible using an active electronic crossover of 12, 18 or 24 dB per octave and a crossover frequency between 80 and 125Hz. No internal wiring change is required for biamp operation because the built-in first-order low-pass filter is only effective above 125Hz. In either mode of operation an active low-frequency protection filter is strongly recommended to reduce unwanted program content below 40Hz. (Bass guitar open low E is approx. 41.2Hz) These very low frequencies are not only potentially damaging to the woofers, they also waste massive amounts of amplifier power and cause needless distortion of the upper frequencies. As seen in the response curve (fig. 1 ), the frequency response of the Force Sub is not flat nor was it intended to be. The requirements of a subwoofer for live performance are radically different from those of a typical living room. Most popular music is inherently bass-heavy, with most of that energy concentrated in the kick drum thump region between 60 and 80Hz. Force Sub has been designed for maximum output efficiency in exactly that range. The use of two specially designed 15 inch woofers results in 36% more cone area than a single 18 inch, and the dual slot-load enclosure design is derived from technology developed for the Electro-Voice X-Array touring systems. It should be noted that the frequency response graph (fig.1 ) was measured in an anechoic (whole space) environment. From a practical standpoint, this is a sort of worst case measurement of low-frequency capability. In actual use, sitting on the floor, the long bass wavelengths will be reinforced by the floor and the room boundaries and will result in more low bass output than the graph implies, depending on the room and the Force Subs position in it. The Force Sub includes a top-mounted stand adapter and a 30 inch pole mount for use with the Force full-range system. Safety concerns limit the use of a pole greater than 30 inches in length, but under no circumstances should the total height of all components exceed 80 inches. Force Sub will handle a long term average power input of 300 watts RMS and realworld peaks of over 600 watts. The input connections are inch phone, but may also be ordered with Neutrik NL4MP connectors (Force Sub-E), which are recommended for sustained high power operation.

Power handling. To our knowledge, Electro-Voice was the first U.S. manufacturer to develop and publish a power test closely related to real-life conditions. 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 long-term average level stresses the speaker thermally (heat). The instanta-
neous peaks test mechanical reliability (cone and diaphragm excursion). Note that the sinewave 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 Force Sub is designed to withstand the power test described in the ANSI/EIA RS-426-A 1980. The EIA test spectrum is applied for eight hours. To obtain the spectrum, the output of a whitenoise generator (white noise is a particular type of random noise with equal energy per bandwidth in Hz) is fed to a shaping filter with 6-dB-per-octave slopes below 40 Hz and above 318 Hz. When measured with the usual constant-percentage bandwidth analyzer (one-third-octave), this shaping filter produces a spectrum whose 3-dBdown points are at 100 Hz and 1,200 Hz with a 3-dB-per-octave slope above 1,200 Hz. Amplifier Recommendations. The power-handling capacity of the Force Sub is 300 watts EIA (350 watts AES). For biamp operation choose an amplifier of approximately 300 watts RMS per channel, full 20-20,000 Hz bandwidth at 8 ohms. For passive operation (Force Sub and Force fullrange connected in parallel) the power capacity of the full-range system must be taken into consideration. Remember that the Force full-range has a lower power-handling capacity than the Force Sub, so above the Force Subs 125 Hz low-pass filter frequency all of the amplifier power is directed to the fullrange system. Only below 125 Hz is the power shared between the two systems, with the Force Sub getting the majority only on the very lowest notes. Therefore, for passive operation select an amplifier whose continuous 8 ohm rating, full 20-20,000 Hz bandwidth, is appropriately sized to the fullrange system (a nice size for the Force is approximately 200 to 300 watts RMS @ 8 ohms continuous power per channel) and whose 4 ohm rating per channel is near the total for both systems. This class of amplifier, especially if it also incorporates good on-board limiters, provides plenty of power where you need it down in the bass region where both systems are drawing power in short duration pulses, but not so much as to seriously endanger the more delicate highfrequency components. An amplifier that matches this description very well is the Electro-Voice Q44, which is ideally suited to powering a Force or a passively crossed (parallel connected) Force and Force Sub system in stereo. Using an active (electronic) crossover, the Electro-Voice Q66 is an ideal choice for powering up to four Force Subs. WARNING: Under NO Circumstances should ANY amplifier be used in Bridge Mode. Bridging an amplifier results in abnormally high peak voltage levels that can destroy your speakers.
