Visaton BF 32 - 4 Micro Speaker

The Visaton BF 32 - 4 Micro Speaker is a compact audio solution engineered to deliver clear, reliable sound in the most space-constrained applications. Measuring just 32mm in diameter with a depth of only 13mm, this miniature driver is ideal for integration into portable electronics, alarm systems, small enclosures, and custom DIY projects where a full-range speaker simply cannot fit. Its low-profile design makes it particularly suited for use in handheld devices, model building, and compact audio indicators where size is at a premium.

Technically, the BF 32 - 4 features a 4-ohm impedance and a maximum power handling of 5 watts, allowing it to produce a sensitivity of 78 dB SPL at 1 metre with 2.83V input. The resonance frequency is a low 28 Hz for its size, while the 19mm voice coil and four mounting holes ensure stable, long-term performance. The cut-out diameter for the baffle is 31.5mm, and the mounting hole diameter is 2mm, facilitating straightforward installation. With its robust construction and Visaton’s renowned engineering, this micro speaker offers dependable audio reproduction for demanding compact applications.
