This versatile 6.5-inch (165.1mm nominal diameter) transducer excels in both sealed and ported enclosures, offering a balanced response that suits a wide range of applications.

Ideal for use in high-fidelity home audio systems, studio monitors, or custom car audio installations, the 6B30/P provides accurate bass and midrange performance. Its total Q factor of 0.5 ensures a well-damped, tight sound, while the 90dB sensitivity (1m/2.83V) allows for efficient power handling and dynamic output. With a maximum linear excursion (Xmax) of 5.5mm and a displacement volume (Vd) of 77, this driver can produce substantial low-end impact without distortion.

Technical features include a 5.5-ohm DC resistance (Re) and a 0.3mH voice coil inductance (Le), contributing to clean signal reproduction. The mechanical Q (Qms) of 3 and electromagnetic Q (Qes) of 0.6 work together to achieve the overall Qts of 0.5. The driver is secured with four mounting holes on a 156mm screw circle, and the baffle cutout diameter is 141mm.
