Large-format waveguide and narrow 30° x 20° pattern designed for use with other LT loudspeakers to form Coherent Zone arrays in medium to large permanent installations requiring precise coverage and high intelligibility.
For indoor and outdoor applications.
The 2-way, mid/high-frequency loudspeaker shall contain a 3" (76 mm) diaphragm compression driver and four (4) midrange manifolds, each summing two (2) 4.5" (114 mm) cone drivers in a heat-sink/acoustic summation assembly. The transducers will exit into a large-format waveguide with 30° x 20° nominal beamwidth and effective pattern control to approximately 1 kHz. An internal filter network with crossover of 1.6 kHz shall allow passive or bi-amp operation.
On-axis system frequency response shall be 220 Hz to 16 kHz (+/- 3 dB) with recommended crossover and active equalization. The system sensitivity shall be 110 dB SPL with 1 watt input and be capable of producing peak output of 140 dB SPL on axis at 1 meter. In passive mode, the system shall handle 280 watts of amplifier power (IEC 268-5 pink noise, 6 dB crest factor, for 100 hours) and have a nominal input impedance of 16 ohms. In bi-amp mode, the mid-frequency section shall handle 280 watts of amplifier power and have a nominal input impedance of 16 ohms (or two discrete 8 ohm loads, selectable). The high-frequency section shall handle 75 watts of amplifier power and have a nominal input impedance of 8 ohms.
The trapezoidal enclosure shall be constructed of void-free, exterior-grade Baltic birch plywood with extensive internal bracing. The enclosure interior shall be treated with wood sealer and the exterior finished with a two-part spray polyurethane coating (Chemthane 7030 or equivalent) to resist weather elements and scuffing. The enclosure shall be covered by a 16-gauge perforated stainless steel grille with powder-coated finish and backed with an open-cell foam. The loudspeaker shall survive water incursion consistent with the IEC 529 IPX5 rating. The enclosure shall have sixteen (16) stainless steel threaded inserts (4 each: top, bottom, sides) that accept standard SAE 3/8"-16 rigging hardware. Inputs shall be two (2) NL8 Neutrik® Speakon® connectors. Loudspeaker dimensions shall be 42.2" x 22.5" x 39.2" (1072 mm x 573 mm x 997 mm). Net weight shall be 195 lb (88.4 kg).
The 2-way, mid/high-frequency loudspeaker shall be the Bose® LT 3202® WR loudspeaker.
