Visaton K 28 40 H - 8 Bass-midwoofer

The Visaton K 28.40 H - 8 Bass-midwoofer is a compact yet powerful driver designed to deliver clear, detailed sound reproduction in space-constrained speaker systems. As a wideband unit, it excels at handling both bass and midrange frequencies, making it an ideal choice for small bookshelf speakers, multimedia enclosures, or custom audio projects where full-range performance is required without sacrificing precious cabinet volume. Its neodymium magnet ensures high efficiency and a lightweight construction, allowing for versatile placement even in portable or wall-mounted designs.

Technically, this driver features an impedance of 8 ohms and a sensitivity of 79 dB SPL at 2.83V/1m, providing reliable output for moderate-power amplifiers. With a resonance frequency of 58 Hz, it offers solid low-end extension for its size, while the 69.5 x 33 mm frame and 5.2 mm mounting hole diameter simplify integration into pre-cut baffles. The neodymium magnet material contributes to a shallow 16 mm depth, enabling slim enclosures without compromising magnetic strength. Two mounting holes ensure secure installation, and the wideband woofer type means it can handle a broad frequency range, reducing the need for additional crossover components in simple designs. Whether for a DIY hi-fi project or a commercial upgrade, this Visaton driver combines efficiency, compactness, and dependable audio performance.
