ULTRA-X40 Compact Loudspeaker

The loudspeaker shall be a self-powered, full-range system. The transducers shall consist of two 8 in cone drivers and one 3 in diaphragm compression driver connected to a 110° x 50° rotatable 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 highand low-frequency sections. Peak output power shall be 1950 W total with
nominal 8 Ω resistive load for the high-frequency channel and 4 Ω 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 53 Hz – 19.5 kHz; phase response shall be 89 Hz – 18 kHz ±45°; linear peak SPL shall be 132.5 dB measured with M-noise, free-field at 4 m referred to 1 m; Coverage (–6 dB points) shall be 110° by 50°, horizontal or vertical dependent on horn orientation.

The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal 0 dBV (1 V rms) signal. Connector shall be XLR 3-pin female male loop.

The internal power supply shall perform automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Powering requirements shall be nominal 100, 110 or 230 V AC line current at 50 or 60 Hz. UL and CE operating voltage range shall be 100–240 V AC. Maximum peak current draw during burst shall be 3.1 A rms (115 V AC), 1.5 A rms (230 V AC), and 3.4 A rms (100 V AC). Current inrush during soft turn-on shall not exceed 20 A at 115 V AC. AC power connector shall be powerCON.

The loudspeaker system shall provide facilities for installing Meyer Sound’s optional RMS remote monitoring system. All loudspeaker components shall be mounted in an acoustically vented trapezoidal enclosure constructed of premium multi-ply birch with a slightly textured black finish. The front protective grille shall be powder-coated, round-perforated steel. Dimensions shall be W:  12.51  in (318  mm) x H: 22.31 in (567 mm) x D: 14 in (356 mm) or 15.38 in (391 mm) with handles. Weight shall be 52 lb (23.6 kg).

The loudspeaker shall be the Meyer Sound ULTRA-X40.
