The Sonance Blaze Audio BL118SSi is a high-output sub-bass companion subwoofer housed in a tour-grade enclosure built to withstand the rigors of professional production deployment. A single 18-inch driver provides usable bandwidth from 18 Hz to 150 Hz at -10 dB, delivering the low-frequency extension required for large-format music reinforcement, dance-floor reproduction, and high-SPL touring applications.

Power handling is rated at 2500W into 4 ohms, giving the BL118SSi the headroom to support extended program material without thermal compression. The black tour-grade cabinet is built for repeated transport, setup, and tear-down across multiple venues, and pairs naturally with the broader Blaze Audio loudspeaker family in arena, ballroom, club, and large house-of-worship deployments.

The BL118SSi is sized for the production touring market: built tough enough to survive repeated load-in and load-out, and tuned with the extended bandwidth required for music reinforcement at high SPL. Pair with matching CBL or Blaze tops for a complete tour-grade rig.
