Architect's & Engineer's Specifications The compact powered PoE++ loudspeaker shall have a frequency response from 65 Hz to 20 kHz (10 dB below rated sensitivity, when wall mounted, with no external equalization). Nominal impedance shall be 8 ohms. The peak SPL with inaudible distortion shall reach 101 dB with music as a source, when measured at a distance of 1 m driven to full output capacity. The system shall consist of a 5.25 inch (133 mm) low frequency high performance transducer with 1 inch (25 mm) voice coil and a 0.78 inch (20 mm) ferrofluid cooled dynamic tweeter with PEI diaphragm and 0.78 inch (20 mm) voice coil. The nominal radiation pattern shall be 90° in horizontal plane and 60° in vertical plane. The powered, bi-amplified PoE++ loudspeaker shall have an RJ45 Ethernet connector on the rear panel. This connector shall accept a Dante or AES67 signal for audio, as well as the PoE++ power voltage per IEEE 802.3bt Type 3. There shall be an external, 5.5 mm by 2.1 mm barrel type, power input jack, which will accept external 24 V DC power supplies, capable of delivering 2.7 A of filtered DC power. The system power amplifiers shall have an unfiltered frequency response of 20 Hz to 20 kHz which deviates no more than +0, -3 dB up to rated power, hum and noise better than 90 dB below rated power, and THD and IMD less than 1%. The woofer amplifier shall be capable of 20 watts sine wave power output into an 8 ohms nominal load, and the tweeter amplifier shall be capable of 20 watts sine wave power into 8 ohms nominal load, before compression and/or limiting engage. The input signal shall be electronically divided into high frequencies and low frequencies by a line-level electronic crossover. The low frequencies shall be processed to provide bass boost, subsonic filtering and overall response shaping. High frequencies shall be equalized for response shaping. The enclosure shall be constructed of injection-molded plastic with a UL94V0 flame rating, and reinforcing ribs internally. An U-Bracket shall be supplied with the speaker system for wall-mount use, held in place with two M6 threaded knobs, one each on top and bottom. An aluminum grille shall be provided for overall driver protection. The loudspeaker shall be 9.96 inches (253 mm) high by 7.28 inches (185 mm) wide by 7.44 inches (189 mm) deep, weighing 5.7 pounds (2.6 kg) including the U-Bracket. The finish shall be a matte black paint in RAL 9004. Power requirements shall be: PoE++ IEEE 802.3bt Type 3, nominally via a 60 watts rated power injector or powered PoE++ switch (not included) or an external power supply of 24V DC at 2.7 A (not included). The compact PoE++ powered loudspeaker system shall be the Crest Audio CIP 5 with included U-Bracket or approved equivalent.
