About the M1/Maria 800 Bi-Amplified

The Daniel Hertz M1/Maria 800 Bi-Amplified is a high-efficiency, three-way reference loudspeaker system comprising a pair of M1 loudspeakers and one Maria 800 four-channel integrated amplifier. Each M1 uses separate low- and mid/high-frequency amplifier connections: the Maria 800 directly drives the 18-inch bass driver through its active crossover, while the 12-inch mid-bass driver and compression-driver tweeter are connected through the system’s configured amplification and crossover architecture. The system is designed for extremely high dynamic range and output, with Daniel Hertz specifying performance up to approximately 128 dB SPL without audible compression or distortion. The Maria 800 combines DAC, preamplifier, four-channel power amplifier, headphone amplifier, Wi-Fi/Bluetooth connectivity, and programmable active crossover/time-alignment functions in one chassis. Official product information indicates that the M1/Maria 800 system remains part of Daniel Hertz’s current product range; therefore it is not considered discontinued.
