ScanSpeak Automotive Gold Series 16W/4538G05 6.5" Midwoofer specifications
| Diameter Cone diameter — larger cones move more air and reach deeper bass | 6.5" |
|---|---|
| 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 | 70 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 | 36 Hz |
| Qts Total Q at resonance (electrical + mechanical) — guides the sealed vs ported choice | 0.35 |
| Qes Electrical Q at resonance — comes from the magnet motor strength | 0.39 |
| Qms Mechanical Q at resonance — from damping of the surround and spider | 3.82 |
| Vas Equivalent air volume of the suspension compliance — used to size the enclosure | 24 L |
| Sd Effective cone area that actually moves air | 123 cm² |
| Xmax Maximum linear excursion — more travel means louder bass without distortion | 6.6 mm |
| Re DC resistance of the voice coil | 3.1 Ω |
| Le Voice-coil inductance — affects high-frequency response | 0.18 mH |
| Mms Total moving mass, including the air load | 16.9 g |
| BL Motor force factor (magnetic flux × coil length) — higher means tighter cone control | 5.5 T·m |
| Weight Driver weight | 1000 g |
