Atlas Sound SEA-18S Architect And Engineer Specifications, SL1-2086, Loudspeaker Specifications

ARCHITECT AND ENGINEER SPECIFICATIONS

Unit shall be Atlas Sound Model I8S. The loudspeaker system shall include factory assembled loudspeaker, IP addressable PCB amplifier/ control and metal baffle.The loudspeaker shall have a 10oz (260g) ceramic magnet and a seamless cone. Frequency response range shall be 86Hz to 8kHz (-3dB). Sensitivity shall be 94dB average. Voice coil former shall be black anodized aluminum to help dissipate heat, have an impedance of 8 Ohms and a diameter of 1” (25mm). The IP addressable PCB amplifier/control shall be mounted to the rear of the loudspeaker baffle via concealed weld studs. The amplifier / control PCB shall be capable of producing 9 Watts RMS with a minimum

of 9VDC power provided either locally or via Cisco IEEE 802.3AF

compliant POE switches. Interconnect shall be via female RJ-45 connector mounted to the PCB. All control functionality of the PCB amplifier shall be determined via software. The metal loudspeaker baffle overall dimensions shall be 11.5” (292mm) wide by 11.5” (292mm) tall. Baffle construction shall be of 18 gauge cold rolled steel. Finish shall be Atlas Sound neutral white electrostatic powder coat. Optional enclosures shall include models SEA-I8S surface mount angled enclosure for I8S - neutral white finish, SEST-I8S surface mount straight enclosure for I8S - neutral white finish and FEST-I8S flush mount straight enclosure for I8S - reclaimed powder coat finish.
