Optimized as the high frequency section of the Project Two Series, its applications include sound reinforcement, musical playback and public address. The cabinet is constructed of heavy duty 7 ply, %" plywood, finished in black splatter paint and then reinforced with steel corners. The system is comprised of a 22A™ compression driver coupled to a CH™-1 constant directivity (90° H * 45° V) horn, with a premium passive crossover to properly interface the MF1-X into a multi-way component speaker system. The crossover includes a filtered output for the low end of a system, and attenuation and equalization for the highs; an unattenuated input to the driver is included to allow use with an active crossover system. Two Vi" female connectors in parallel are provided for full-range input with a full-range signal in, one Vi" female connector for lows out and one Vi" female connector for biamp highs only. Crossover Frequency: 600 Hz Crossover Type: Passive Crossover Slope: 12 dB/octave high pass 6 dB/octave low pass for biamp low out Impedance (Nominal): 8 ohms Impedance (Minimum): 5.6 ohms Input Connections: Two full-range female connectors in parallel, one low out and one biamp high only, Vi" female connectors Enclosure Materials and Finish: High density, 7 ply, %" plywood splatter-painted black Dimensions: 30%" (78.4 cm) W * 161/4" (41.3 cm) H x 500-10,000 Hz 23%" (60.6 cm) D 80° +/-40° Net Weight: 10,000-16,000 Hz 63 lbs (28.6 kg) 45°+/- 5° FREQUENCY RESPONSE The frequency response of the MF1-X™ Mark III™ is measured in an anechoic environment at a distance of 1 meter while using a 2.82 volt logarithmically swept sine input. This measurement is useful in determining the accuracy in which the enclosure reproduces the input signal. The combination of the 22A™ compression driver on the CH™-1 horn and the premium crossover results in a flat desirable response as shown in Figure 1. DIRECTIVITY Beamwidth and directivity factors are derived from the -6 dB points from the polar plots (see Figure 3) which are measured in a whole space anechoic environment. These are specifications which provide a reference to the coverage characteristics of the enclosure. These parameters provide insight for proper enclosure placement and installing the chosen environment. The blending of the MF1-X Mark III components exhibit a desirable beamwidth and directivity factor (Figures 4 and 5) suitable for all high level sound reinforcement applications. POWER HANDLING There are many different approaches to power handling ratings, the most common being EIA standard RS-426A. The derived shape of this test spectrum was an attempt to simulate the spectral content of contemporary music. Although it does resemble contemporary music, EIA-RS-426A does-not contain the same levels of very low frequency material found in live music situations. Very high levels of low frequency material produce distortion and, ultimately, device failure. The presence of the low frequency material will therefore yield lower device ratings ...
