SB Acoustics Satori TW29D Tweeter specifications
| Impedance Voice-coil electrical resistance — must match your amplifier (e.g. 4Ω/8Ω) | 4 Ω |
|---|---|
| Power (RMS) Continuous power the driver handles safely (RMS) — not peak power | 80 W |
| Sensitivity (SPL) Sensitivity — loudness at 1W/1m; higher means louder with less amplifier power | 93 dB |
| Fs Free-air resonance frequency — lower generally means deeper bass extension | 600 Hz |
| Qts Total Q at resonance (electrical + mechanical) — guides the sealed vs ported choice | 0.81 |
| Qes Electrical Q at resonance — comes from the magnet motor strength | 1.27 |
| Qms Mechanical Q at resonance — from damping of the surround and spider | 2.2 |
| Sd Effective cone area that actually moves air | 9.6 cm² |
| Xmax Maximum linear excursion — more travel means louder bass without distortion | 0.25 mm |
| Re DC resistance of the voice coil | 3 Ω |
| Le Voice-coil inductance — affects high-frequency response | 0.02 mH |
| Mms Total moving mass, including the air load | 0.45 g |
| BL Motor force factor (magnetic flux × coil length) — higher means tighter cone control | 2 T·m |
| Weight Driver weight | 550 g |
