SB Audience Rosso 8CX250 8" Coaxial specifications
| Diameter Cone diameter — larger cones move more air and reach deeper bass | 8" |
|---|---|
| Impedance Voice-coil electrical resistance — must match your amplifier (e.g. 4Ω/8Ω) | Woofer 8 Ω / Tweeter 8 Ω |
| Power (RMS) Continuous power the driver handles safely (RMS) — not peak power | Woofer 250 W / Tweeter 50 W |
| Sensitivity (SPL) Sensitivity — loudness at 1W/1m; higher means louder with less amplifier power | Woofer 94 dB / Tweeter 102 dB |
| Fs Free-air resonance frequency — lower generally means deeper bass extension | 70 Hz |
| Qts Total Q at resonance (electrical + mechanical) — guides the sealed vs ported choice | 0.32 |
| Qes Electrical Q at resonance — comes from the magnet motor strength | 0.37 |
| Qms Mechanical Q at resonance — from damping of the surround and spider | 2.19 |
| Vas Equivalent air volume of the suspension compliance — used to size the enclosure | 15.8 L |
| Sd Effective cone area that actually moves air | 211.2 cm² |
| Xmax Maximum linear excursion — more travel means louder bass without distortion | 5.4 mm |
| Re DC resistance of the voice coil | 5.3 Ω |
| Le Voice-coil inductance — affects high-frequency response | 0.72 mH |
| Mms Total moving mass, including the air load | 20.8 g |
| BL Motor force factor (magnetic flux × coil length) — higher means tighter cone control | 11.4 T·m |
| Weight Driver weight | 4320 g |
