Banda Electra Bass 3K4 Amplifier Module 3000 Watts RMS 4 ohms

ELECTRA Series – Ultra-Clean Power for High-Efficiency Systems | 4 Ohms Version

The ELECTRA 4 Ohms amplifier is designed for those who demand clean, controlled, and powerful bass performance with maximum efficiency. Ideal for high-sensitivity subwoofer setups and midbass applications, this model delivers up to 3700 WRMS at 14.4V / 4 Ohms, and operates with an exceptional efficiency of 92% at 8 Ohms.

Its extended frequency response of 5Hz to 500Hz (-3dB) when the limiter is off, and standard 20Hz to 500Hz range in normal mode, ensures precise and impactful low-frequency playback. The adjustable Bass Boost @ 45Hz allows up to +18dB gain, giving users full control over their system’s low-end response.

Built with a robust aluminum chassis, the amplifier includes advanced protections (thermal and short-circuit), a Clipping Indicator, and temperature-controlled micro fans, ensuring safe and efficient performance even under demanding use.

With a sleek, bold design and excellent power-to-efficiency ratio, the ELECTRA 4 Ohms is an ideal choice for audiophiles and professionals alike.
