RCF LF12G301 - 900W 12-inch Ceramic Low-Frequency Driver with 3-inch Voice Coil and 8-Ohm Impedance in Black Finish

The RCF LF12G301 is a high-performance 12-inch ceramic low-frequency driver designed to provide exceptional power handling, low distortion, and high efficiency. With a continuous program power handling of 900W, this driver is ideal for demanding audio applications that require deep bass reproduction with clarity and precision. Its robust design, including a copper voice coil, ensures reliability and durability even under extended use, while its carefully engineered materials ensure it can handle up to 450W RMS power without compromising performance.

The LF12G301 features a 3-inch fiberglass inside/outside copper voice coil, providing excellent power handling and maintaining a lightweight structure for fast transient response. The copper winding material ensures high thermal conductivity, which helps dissipate heat efficiently during long periods of operation. The driver's excellent heat dissipation capabilities are further enhanced by its M-roll surround and curved cone design, which together offer excellent excursion control and minimize distortion even during high-excursion operation.

With a frequency range of 40 Hz to 2000 Hz and a sensitivity of 97 dB, the LF12G301 delivers accurate and impactful bass reproduction while maintaining clarity in mid-bass frequencies. The driver features a maximum excursion before damage of 36 mm and a maximum linear excursion of 7 mm, making it capable of handling significant low-frequency signals with precision and without distortion. The ceramic magnet structure ensures excellent efficiency and power handling, while the driver's overall design ensures high output and long-lasting performance.

Whether used in subwoofer systems, mid-bass drivers, or high-output audio systems, the LF12G301 offers exceptional performance, durability, and reliability. Its powerful, efficient design makes it ideal for professional sound reinforcement systems, while its low distortion and high sensitivity ensure it reproduces accurate, dynamic sound across a wide range of frequencies.
