Technically, the SB15NRXC30-4 boasts a sensitivity of 91 dB (SPL 1m/2.83V), allowing for efficient power handling and dynamic response. The 30.48 mm voice coil and 5 mm linear excursion (Xmax) contribute to robust performance, while the low voice coil inductance of 0.12 mH minimises distortion at higher frequencies. With a resonance frequency of 41 Hz and an equivalent volume (Vas) of 16.42 litres, it offers flexibility in cabinet design. The DC resistance is 3.1 ohms, and the impedance is rated at 4 ohms. Mechanical (Qms 5.3) and electrical (Qes 0.31) damping factors are well-balanced, ensuring controlled transient response. This driver is a refined choice for audiophiles seeking precision and musicality in their projects.
