Integrated rigging points let it hang from the ceiling or a side wall, which makes it a strong choice for bass-management surround duty in Dolby Atmos rooms. Its 18-inch driver uses a neodymium magnet structure for low weight and a high-temperature voice coil with a large Xmech rating for reliable operation.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby 118-I-BK work?\u003c\/h2\u003e\n\u003cp\u003eIn a Dolby Atmos auditorium the cinema processor routes low-frequency content from the surround and overhead arrays to bass-management subwoofers. The 118-I-BK fills that role from an elevated position, close to the surround speakers it supports. It is a passive cabinet driven by an external amplifier channel at 8 ohms and is rated at 600 W (64 V).\u003c\/p\u003e\n\u003cp\u003eThe operating range is 35 Hz to 160 Hz with 99 dB sensitivity, and the calculated maximum output is 127 dB continuous and 133 dB peak at one metre. Angled woofer placement keeps the front surface area small, so the cabinet is less visually intrusive on the wall. The 13-ply wood enclosure is extensively braced, and sixteen M10-1.5 threaded inserts provide rigging points for flying or wall mounting.\u003c\/p\u003e\n\u003cp\u003eSignal usually comes from a \u003ca href=\"https:\/\/creationnetworks.net\/products\/dolby-atmos-cinema-processor-cp950a\"\u003eDolby CP950A\u003c\/a\u003e processor through a Dolby Multichannel Amplifier such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/dolby-professional-multichannel-amplifier\"\u003eDMA16302\u003c\/a\u003e.
