Architectural Specifications
The loudspeaker shall be a self-powered, full-range system. The transducers shall consist of two 5-inch cone drivers and one 2-inch diaphragm compression driver connected to horns with different coverage depending on the model: the wide coverage model shall have a 110° x 50° rotatable horn, the narrow coverage model shall have a 80° x 50° rotatable horn, and the broad coverage shall have a 110° x 110° horn.
The loudspeaker system shall incorporate internal processing electronics and a three-channel, class-D amplifier. Processing functions shall include equalization, phase correction, signal division and protection for the high and low-frequency sections. Peak output power shall be 860 W total with 8 Ω nominal impedance for the high-frequency channel and 6 Ω nominal impedance for the low-frequency channels. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit shall be as follows: operating frequency range shall be 60 Hz – 18 kHz; phase response shall be 95 Hz – 18 kHz ±45°. Linear peak SPL for the wide coverage version shall be 127 dB with 20 dB crest factor, measured with M-noise, free-field at 4 m referred to 1 m, and its coverage pattern (–6 dB points) shall be 110° by 50°, horizontal or vertical dependent on horn orientation. Linear peak SPL for the narrow coverage version shall be 128.5 dB with 20 dB crest factor, measured with M-noise, free-field at 4 m referred to 1 m, and its coverage pattern (–6 dB points) shall be 80° by 50°, horizontal or vertical dependent on horn orientation. Linear peak SPL for the broad coverage version shall be 127.5 dB with 20 dB crest factor, measured with M-noise, free-field at 4 m referred to 1 m, and its coverage pattern (–6 dB points) shall be 110° by 110°.
The audio input shall be electronically balanced with a 10 kΩ impedance and shall accept a nominal 0 dBV (1 V rms) signal. The connector shall be a Phoenix 5-pin male.
Power requirements for the loudspeaker shall be a Meyer Sound MPS IntelligentDC power supply capable of delivering 48 V DC. Meyer Sound’s RMS remote monitoring system shall be optionally available via the MPS-488HP power supply.
All loudspeaker components shall be mounted in an acoustically vented enclosure constructed of aluminum with a slightly textured black finish with two integrated M8 threaded points on each end and four M6 threaded holes with a 5-inch by 2.75-inch (127 mm by 70 mm) hole pattern on the rear. The front protective grille shall be powder-coated, round-perforated steel. Dimensions shall be W: 7.44 in (189 mm) x H: 19.04 in (484 mm) x D: 8.66 in (220 mm).
Weight shall be 27 lb (12.3 kg).
The wide coverage loudspeaker model shall be the Meyer Sound ULTRA-X20XP, the narrow coverage loudspeaker model shall be the Meyer Sound ULTRA-X22XP, and the broad coverage loudspeaker model shall be the Meyer Sound ULTRA-X23XP.
