Upgrade your HDL 50-A with 4K

The 4K amplifier is an essential part of the HDL 50-A reengineering effort. The 4000 W RMS Class-D power operates at very low impedance producing a quick and detailed transient response, while the high damping factor improves sound quality and detail.

The HDL 50-A 4K power section is tailored to the transducers and the cabinet design to reach excellent efficiency, low distortion and high signal-to-noise ratio. 4000W RMS class-D amplifier - 1000W for the HF, 1000W for the Midrange section and 1000W+1000W for the LF for a quick and detailed transient response.

The most powerful HDL amplifier ever made by RCF

The 4K amplifier doubles the power of the HDL 50-A to achieve new levels of clarity and absence of distortion.
Transducers work at full performance and the SPL output is more than doubled. Furthermore, we improved the power supply section with a tripled current level on fast transients, for a level of detail usually achieved only in high-end studio monitors.
