Meyer Sound 900-LFC Low-Frequency Array Speaker/3-Pin/Remote Monitoring/Weather Protection Hood/Rig
Meyer Sound’s 900-LFC compact low-frequency control element reproduces low frequencies at high continuous output levels with extremely low distortion. The 900-LFC offers the same sonic linearity as Meyer Sound’s 1100-LFC low-frequency control element in a smaller, lighter cabinet, making it ideal for building scalable systems to suit touring applications or fixed installations of any size.
MRK-900 Rigging Kit
The optional MRK-900 rigging kit allows the 900-LFC to be flown and groundstacked with the MG-LEOPARD/900 multipurpose grid. The kit also allows 900-LFCs to be flown and groundstacked with LEOPARD with no transition hardware. The rigging kit is available as a factory-installed option or as a field upgrade and uses rugged GuideALinks and intuitive quick-release pins to securely link adjacent loudspeakers in flown and groundstacked array configurations.
LEOPARD/900-LFC Collapsible Rain Hood Attachment:
The Collapsible LEOPARD/900-LFC Rain Hood Kit includes the following parts:
