HiVi M5N-B Bass-midwoofer

The HiVi M5N-B 5-inch Damped Aluminium/Magnesium Cone Woofer is a precision-engineered bass and mid-bass driver designed to deliver exceptional clarity and control. Combining a lightweight yet rigid aluminium/magnesium cone with a damping treatment, this woofer minimises unwanted resonances for a clean, accurate sound reproduction.

Ideal for use in high-fidelity loudspeaker systems, the M5N-B excels as a dedicated mid-bass driver or as part of a multi-way design. Its compact 5-inch (127 mm) nominal diameter makes it well-suited for bookshelf speakers, small floor-standing enclosures, or automotive audio installations where space is at a premium but performance cannot be compromised. The driver’s low total Q factor (Qts) of 0.35 ensures tight, controlled bass response, making it an excellent choice for sealed or ported enclosures.

Technically, the M5N-B features a ferrite magnet motor with a DC resistance (Re) of 6.5 ohms and a sensitivity of 87 dB SPL (1m/2.83V). The mechanical Q (Qms) of 6.51 and electromagnetic Q (Qes) of 0.37 contribute to its precise damping characteristics. With a maximum linear excursion (Xmax) of 2.7 mm, this woofer handles moderate power levels while maintaining low distortion. The cut-out diameter is 115 mm, with a screw circle of 133 mm and a mounting depth of 95 mm, ensuring straightforward installation.

In summary, the HiVi M5N-B delivers a refined balance of bass extension and midrange clarity, making it a reliable choice for discerning audio enthusiasts seeking high-quality sound in a compact form factor.
