Visaton BF 30 R 4 Ohm 3 cm Ηχείο ευρείας ζώνης Μαύρο

The Visaton BF 30 R is a 3 cm full-range driver that delivers clear, balanced sound from a remarkably compact chassis. Its neodymium magnet system and paper cone with rubber surround provide efficient output and reliable performance in tight installations.

Advantages

This driver combines a shallow mounting depth of just 13.5 mm with a wide frequency range of 200–20,000 Hz. The 4-ohm impedance allows easy integration into small audio systems, while the rubber surround improves durability and reduces distortion at higher excursions.

Suitable for

• Portable Bluetooth speakers and smart home devices
• Compact multimedia systems and desktop monitors
• Model making, robotics, and DIY audio projects
• Replacement driver for small full-range applications

Recommendations

Pair with a small sealed or vented enclosure of 0.05–0.1 litres for optimal bass response. Use a low-pass filter below 15 kHz if high-frequency beaming is noticeable. Ensure the amplifier can deliver at least 5 W into 4 ohms for full output.
