HiVi M4N-B Full-Range Driver

The HiVi M4N-B 4-inch full-range driver delivers exceptional clarity and detail in a compact form factor, making it an ideal choice for high-fidelity audio projects where space is at a premium. Its damped aluminium/magnesium cone provides a remarkable balance of stiffness and lightness, ensuring precise transient response and low distortion across the frequency range. This driver is perfectly suited for use in small bookshelf speakers, desktop monitors, or multi-channel home theatre systems where a single driver must handle both midrange and treble duties without the need for a separate tweeter. It also excels in custom installations, such as automotive audio upgrades or portable Bluetooth speaker builds, where its shallow 67mm depth allows for versatile enclosure design.

Technically, the M4N-B features a robust ferrite magnet motor coupled with a 20mm voice coil, delivering controlled power handling and a total Q factor (Qts) of 1.08, which indicates suitability for sealed or slightly ported enclosures. With a resonant frequency (Fs) of 69Hz and an equivalent volume (Vas) of 4.3 litres, it can produce surprising bass extension for its size. The mechanical (Qms) and electrical (Qes) Q factors of 5.39 and 1.35 respectively ensure smooth roll-off characteristics, while the 3mm linear excursion (Xmax) allows for dynamic playback without compression. The 108mm frame diameter and 93mm cut-out simplify installation, and the four mounting holes provide secure fixing. Whether for a discerning audiophile or a DIY enthusiast, the HiVi M4N-B offers a refined, low-distortion full-range solution that punches well above its size.
