Meyer Sound 750-LFC 15" Rigging Subwoofer, 3-Pin Input - 09.27...
Product Overview
The Meyer Sound 750-LFC is a very compact self-powered low-frequency control element for scalable low-frequency reinforcement in portable rigs and fixed installations. This configuration ships with QuickFly rigging and a 3-pin balanced audio input, making it ready for flown, ground-stacked, and cardioid subwoofer arrays. A single 15-inch long-excursion driver and an onboard class D amplifier deliver high continuous output with extremely low distortion. It is a natural low-frequency complement for Meyer Sound LINA and LEOPARD systems.
Product Description
This rigging-equipped 750-LFC includes the MRK-750 rigging kit, whose captive GuideALinks allow flying from the MG-MINA/LINA grid in LINA arrays without a transition frame. The end frames support ground-stacked and cardioid configurations and subwoofer-array splay angles of 0, 1.5, 3.25, or 4.75 degrees. This 3-pin input variant carries balanced audio on XLR connectors without RMS signals. Inside, a two-channel open-loop class D amplifier rated at 3100 W peak resides in a field-replaceable module. For a larger 18-inch element consider the Meyer Sound 900-LFC subwoofer, and pair it with the Meyer Sound LEOPARD line array loudspeaker. Browse the full Meyer Sound collection for processing and accessories.
