SB Acoustics Satori WO34HC-8 13.5" Woofer specifications
| Diameter Cone diameter — larger cones move more air and reach deeper bass | 13.5" |
|---|---|
| Impedance Voice-coil electrical resistance — must match your amplifier (e.g. 4Ω/8Ω) | 8 Ω |
| Power (RMS) Continuous power the driver handles safely (RMS) — not peak power | 200 W |
| Sensitivity (SPL) Sensitivity — loudness at 1W/1m; higher means louder with less amplifier power | 89.5 dB |
| Fs Free-air resonance frequency — lower generally means deeper bass extension | 20.2 Hz |
| Qts Total Q at resonance (electrical + mechanical) — guides the sealed vs ported choice | 0.29 |
| Qes Electrical Q at resonance — comes from the magnet motor strength | 0.3 |
| Qms Mechanical Q at resonance — from damping of the surround and spider | 5.37 |
| Vas Equivalent air volume of the suspension compliance — used to size the enclosure | 238 L |
| Sd Effective cone area that actually moves air | 585 cm² |
| Xmax Maximum linear excursion — more travel means louder bass without distortion | 8.3 mm |
| Re DC resistance of the voice coil | 6.8 Ω |
| Le Voice-coil inductance — affects high-frequency response | 1 mH |
| Mms Total moving mass, including the air load | 127 g |
| BL Motor force factor (magnetic flux × coil length) — higher means tighter cone control | 19 T·m |
| Weight Driver weight | 9520 g |
