Visaton BG 20 Full-range Woofer

The Visaton BG 20 is an 8-inch full-range speaker that delivers impressively clear and balanced audio across the frequency spectrum. Designed as a broadband driver, it excels in applications where a single speaker must handle both music and speech reproduction with equal fidelity. This makes it an ideal choice for DIY audio projects, replacement drivers in existing cabinets, or custom installations in public address systems and monitoring setups.

Technically, the BG 20 features an 8-ohm impedance with a DC resistance of 6.2 ohms, ensuring compatibility with a wide range of amplifiers. Its sensitivity of 92 dB SPL at 1 metre with 2.83V input provides efficient sound output, while the total Q factor of 0.44 indicates well-damped performance suitable for sealed or ported enclosures. The speaker boasts a maximum linear excursion of 4 mm and a voice coil inductance of 0.8 mH, contributing to controlled bass response and clear midrange. With a nominal diameter of 203.2 mm and a mounting depth of 89 mm, it fits standard 8-inch cutouts, requiring a baffle cut-out diameter of 184 mm and four mounting holes on a 197 mm bolt circle.
