SB Acoustics SB26ADC-C000-4 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 | 120 W |
| Sensitivity (SPL) Sensitivity — loudness at 1W/1m; higher means louder with less amplifier power | 90 dB |
| Fs Free-air resonance frequency — lower generally means deeper bass extension | 680 Hz |
| Qts Total Q at resonance (electrical + mechanical) — guides the sealed vs ported choice | 1.11 |
| Qes Electrical Q at resonance — comes from the magnet motor strength | 1.88 |
| Qms Mechanical Q at resonance — from damping of the surround and spider | 2.7 |
| Sd Effective cone area that actually moves air | 6.2 cm² |
| Xmax Maximum linear excursion — more travel means louder bass without distortion | 0.6 mm |
| Re DC resistance of the voice coil | 3.2 Ω |
| Le Voice-coil inductance — affects high-frequency response | 0.04 mH |
| Mms Total moving mass, including the air load | 0.38 g |
| BL Motor force factor (magnetic flux × coil length) — higher means tighter cone control | 1.6 T·m |
| Weight Driver weight | 500 g |
