AD-P.HALO The pendant-style integrated subwoofer/satellite system shall incorporate a 6.5-inch subwoofer with paper cone ringed by four 2.75-inch satellite transducers in a single cabinet. The subwoofer and each transducer shall have its own acoustic enclosure within the cabinet. The system shall meet the following performance criteria: conical coverage angle of 110 degrees; effective frequency range of 40 Hz to 20 kHz +0/-10 dB, measured on axis; broadband sensitivity of 86 dB (measured at 1 m with 2.45 V rms input); maximum continuous output of 105 dB SPL and maximum peak output of 111 dB SPL on axis at 1 meter; power handling of 100 watts for 2 hours with an IEC noise signal; nominal impedance of 6 ohms. An internal passive filter network shall provide a crossover at 250 Hz. The loudspeaker system shall have a switchable low-distortion, wide-bandwidth laminated core transformer with taps for 100, 50, 25, and 12.5 watts at 70V and 100, 50, and 25 watts at 100V. The system shall be switchable between 6Ω (bypass) and constant-voltage operation. The loudspeaker shall have an ABS enclosure. It shall have two perforated steel grilles: a round one for the subwoofer and a ring for covering the halo transducers. The grilles shall use a friction-fit retention scheme and the ring grille shall also use screws, for added security. The baffle and grilles shall have either a white (RAL 9010) or black (RAL 9011) paintable finish with UV inhibitors to prevent discoloration. Any logo on the grille shall be removable without leaving a blemish. The loudspeaker enclosure shall have a steel hanger tab for support and shall include two 3.25 m quick-link 2 mm suspension cables with slip-lock fasteners. The loudspeaker connections shall be a locking 4-pole Euro-block that accepts two 12 AWG wire pairs. The loudspeaker shall be listed under UL 1480A. The loudspeaker shall meet or exceed IP-34 for ingress protection. The switchable transformer shall be listed under UL1876 and shall be CE and RoHS compliant. The baffle shall meet UL94-V0 and UL94-5VB flammability ratings and shall comply with IEC60849/EN60849 safety standards. The loudspeaker's enclosure shall be 17.15 in (43.56 cm) high and 13.6 in (34.6 cm) in diameter. The loudspeaker shall weigh no more than 23 lb (10.4 kg). The pendant-style integrated subwoofer/satellite system shall be the QSC AD-P.HALO.
