Subwoofer for CURV 500 Installations
The iSUB is a compact passive subwoofer designed specifically for use in an LD Systems CURV 500 system installation. Its 47Hz–150Hz frequency response and 200-watt RMS power handling will lend a focused and punchy low end to your space, and Sweetwater A/V installation experts note that its shallow-depth enclosure provides flexible placement options, space efficiency, and low weight. The iSUB is also housed in a bass-reflex medium-density fiberboard (MDF) cabinet that’s 0.59 inches thick, sports a durable steel front grille, and has inputs for both speakON and terminal block connectors. Finally, the iSUB has eight M8 flight points and ships with a flat wall or ceiling holder and a set of rubber feet for immediate implementation into your CURV 500 system.
