SB Audience ROSSO-18SW750 Subwoofer

The SB Audience ROSSO-18SW750 is a formidable 18-inch subwoofer engineered to deliver deep, authoritative low-end response in high-output sound reinforcement systems. Whether deployed in professional touring rigs, fixed installation nightclubs, or large-format home cinema setups, this driver excels at reproducing powerful, controlled bass that anchors the entire listening experience. Its robust construction and carefully optimised parameters make it an ideal choice for both vented and horn-loaded enclosures where maximum impact and reliability are paramount.

At the heart of the ROSSO-18SW750 lies a 99 dB sensitivity rating, ensuring impressive output from modest amplifier power. The 8.82 mm linear excursion (Xmax) enables significant air displacement for deep, articulate bass, while the low total Q (Qts) of 0.43 and a favourable electromagnetic Q (Qes) of 0.45 contribute to tight, well-damped transient response. The voice coil, wound with flat copper-clad aluminium wire, offers excellent thermal handling and low inductance (1.59 mH), reducing distortion at high drive levels. With a mechanical Q (Qms) of 10.5, the suspension is finely tuned for controlled cone motion. The 457.2 mm nominal diameter, 426 mm cut-out, and 245.5 mm depth allow straightforward integration into standard enclosures, while the eight mounting holes and 6.9 mm vented pole piece ensure secure installation and efficient cooling. This subwoofer represents a professional-grade solution for those who demand uncompromising low-frequency performance.
