Monacor SPX-32M 3'' Full Range Driver

The Monacor SPX-32M is a 3-inch full-range driver designed to deliver clear, natural sound from compact enclosures. As a broadband subwoofer, it excels in applications where space is limited but audio quality cannot be compromised, making it an ideal choice for custom speaker builds, multimedia systems, or small-scale public address installations.

This driver’s paper cone and 88 dB sensitivity ensure efficient, lifelike audio reproduction across the frequency spectrum. With a nominal diameter of 76.2 mm and a mounting cut-out of 71 mm, it fits neatly into tight spaces, while a depth of just 55 mm allows for slim cabinet designs. The 8-ohm impedance and 6.6-ohm DC resistance facilitate straightforward integration with a wide range of amplifiers. Technical performance is bolstered by a total Q factor (Qts) of 0.56, combining a mechanical Q (Qms) of 7.66 and an electromagnetic Q (Qes) of 0.6, which together promote controlled bass response. A maximum linear excursion (Xmax) of 1.1 mm and a voice coil inductance (Le) of 0.18 mH further contribute to accurate transient behaviour. The copper voice coil wire and four mounting holes simplify installation, while the robust paper membrane ensures durability.

Whether for a bespoke hi-fi project or a commercial sound system, the SPX-32M offers reliable, high-fidelity performance in a compact, easy-to-mount package.
