The Linea Research 44 M20 is the flagship of the 44M Series, delivering 3,000W per channel at 4 Ohms across four channels – 12,000W total, all channels driven simultaneously. In bridged mode, the M20 can deliver up to 10,000W, making it suitable for driving the most demanding subwoofer arrays and large-format loudspeaker systems. Like all 44M Series amplifiers, power figures are continuous rated, not burst or peak specifications. The 96kHz DSP with LIR crossovers and comprehensive VX Limiter suite handles loudspeaker processing onboard.
