Visaton BF 32 S - 4 Full-range Woofer

The Visaton BF 32 S - 4 is a compact full-range broadband woofer designed to deliver clear, articulate audio from even the smallest enclosures. This 4-ohm driver is ideal for applications where space is at a premium yet sound quality cannot be compromised. Perfect for DIY audio projects, portable speaker builds, or upgrading existing compact systems, it brings surprising sonic depth to tight confines.

Engineered for versatility, this woofer excels in scenarios requiring a single driver to handle the entire frequency spectrum. Use it in desktop monitors, multimedia speakers, or as a replacement unit in vintage radios and small-scale audio equipment. Its low power requirement makes it particularly suited to battery-powered or low-wattage amplifier designs.

Technically, the BF 32 S - 4 features a 20 mm voice coil and a sensitivity of 78 dB SPL (1 m / 2.83 V), ensuring efficient performance within its 5-watt maximum power handling. The mounting cut-out diameter is 31.5 mm, with a depth of just 15 mm, and it requires a 2 mm diameter mounting hole for secure installation. Four fixing points simplify integration into custom baffles.

In summary, this Visaton broadband woofer offers a practical solution for achieving full-range sound in compact, low-power audio systems without sacrificing clarity or build quality.
