Technically, this driver features a 31.75mm voice coil and a 3.5mm linear excursion (Xmax), enabling it to handle up to 15 watts of continuous power with a sensitivity of 90dB (SPL 1m/2.83V). The low voice coil inductance of 0.11mH contributes to extended high-frequency response, while the mechanical (Qms 3.64) and electromagnetic (Qes 0.26) damping factors ensure precise transient control. With a resonance frequency of 64Hz and an equivalent volume (Vas) of 5.38 litres, this 4-inch woofer is optimised for compact designs.

The Illuminator series is renowned for its build quality and sonic accuracy, and this model upholds that legacy. For those seeking a refined, articulate bass performance in a small footprint, the Scan-Speak 12MU/4731T00 is an outstanding choice.
