Scan-Speak 5F/8422T01 2'' Full Range Driver

The Discovery 5F/8422T01 is a 2-inch full-range driver from Scan-Speak, engineered to deliver remarkably clear and coherent sound across a wide frequency spectrum. Despite its compact size, this broadband driver excels at reproducing both vocal detail and musical nuance, making it an exceptional choice for designers seeking high-quality audio in space-constrained applications.

This versatile driver is ideally suited for use in small satellite speakers, desktop monitors, and multi-driver line arrays where consistent, full-range performance is essential. Its wideband capability also makes it a compelling option for custom installations, portable audio projects, or any scenario where a single driver must cover the majority of the audible range without the complexity of a crossover.

Technically, the driver features a nominal diameter of 50.8 mm with a mounting cutout of 53.6 mm and a screw circle diameter of 60.5 mm, secured by four mounting holes. The voice coil exhibits a low inductance of 0.07 mH, contributing to extended high-frequency response. With a sensitivity of 80 dB SPL (1m/2.83V) and a DC resistance of 6 ohms, it offers efficient operation. The total Q factor (Qts) of 0.61, combined with a mechanical Q (Qms) of 5.17 and an electromagnetic Q (Qes) of 0.69, ensures well-controlled bass behaviour. A maximum linear excursion (Xmax) of 2 mm and a depth of 33 mm complete the specification.

In summary, the Discovery 5F/8422T01 provides a refined, full-range solution for compact audio designs, backed by Scan-Speak’s renowned engineering and build quality.
