Sonance BL18S – 18-Inch Passive Subwoofer
Product Overview
The Sonance BL18S is an 18-inch passive subwoofer built for commercial and hybrid venue sound reinforcement. It is intended for integrators pairing it with Sonance's CBL constant beamwidth loudspeaker series to deliver full-range coverage in bars, venues, and multipurpose rooms. Its fixed-installation cabinet still includes casters and handles for occasional repositioning.
Product Description
The BL18S houses a single 18-inch driver in a Baltic birch plywood and engineered plastic enclosure, rated for 1200W AES program power (2400W at 8-ohm continuous, 4800W peak) with a frequency response of 31Hz-150Hz at -10dB and a peak SPL of 136dB. A 14-gauge perforated steel grille with a powder-coated black finish protects the driver in venues with heavy foot traffic or occasional equipment movement. The subwoofer is designed to complement Sonance's CBL Constant Beamwidth Loudspeaker series for a full-range commercial sound system, and it is compatible with Blaze Audio PowerZone Connect amplifiers such as the 3004+. Selectable omni or cardioid dispersion lets integrators tune low-frequency spread for the room, reducing unwanted bass buildup on stage or behind the mix position. Browse the full Sonance commercial audio lineup at Creation Networks, including matching subwoofers and CBL loudspeakers for a complete system. Built-in casters and handles make the 131.5 lb cabinet practical to move between storage and stage for touring or multipurpose room use, even though it is designed as a fixed-installation subwoofer.
