SB Audience ROSSO-8CX250 Coaxial Woofer

The SB Audience ROSSO-8CX250 is an 8-inch coaxial subwoofer that delivers powerful, space-saving bass performance without compromising on audio quality. Designed for those who demand deep, controlled low frequencies in compact installations, this driver integrates a woofer and tweeter into a single chassis, simplifying system design and reducing enclosure volume requirements. Its coaxial configuration makes it an ideal choice for high-end car audio, home theatre subwoofers, and professional sound reinforcement where space is at a premium but performance cannot be sacrificed.

Technically, the ROSSO-8CX250 boasts a total Q factor (Qts) of 0.32, indicating excellent transient response and suitability for sealed or ported enclosures. With a sensitivity of 94 dB SPL (1m/2.83V) and a maximum linear excursion (Xmax) of 5.4 mm, it combines efficiency with the ability to move significant air. The voice coil features an EISVCAW wire material for enhanced thermal handling, while the DC resistance (Re) is 5.3 ohms. Mechanical (Qms 2.19) and electromagnetic (Qes 0.37) damping are carefully balanced, and the voice coil inductance (Le) of 0.72 mH ensures smooth high-frequency extension. The subwoofer’s mounting diameter is 177.2 mm, with an overall nominal diameter of 203.2 mm, and it requires a cut-out of 177.2 mm, secured by eight mounting holes on a 195 mm bolt circle.

This coaxial subwoofer offers a refined solution for achieving deep, articulate bass in compact systems, combining engineering precision with practical installation ease.
