About the Spatial Audio M3 Triode Master
The Spatial Audio M3 Triode Master (M3TM) is a 2-way open baffle speaker system that combines two 15" paper cone mid/woofers with a coaxially mounted 1" throat dipolar compression driver. This design includes a rear-firing outlet on the compression driver to enhance dispersion and create a wide, enveloping soundstage. The speaker features impedance and phase compensation circuitry to optimize compatibility with tube amplifiers, especially those with higher source impedance. Premium components such as Duelund wiring and ClarityCap capacitors are used in the crossover network. The M3 Triode Master offers a neutral, linear voice with a narrow depth form factor suitable for both large and small rooms. It is highly regarded for its exacting imaging, broad uncolored off-axis coverage, and airy, expansive soundstage. The nominal impedance is around 16 ohms with a flat phase response, making it tube-friendly. Sensitivity is approximately 92-93 dB, allowing efficient drive with low-powered amplifiers. The speaker measures approximately 42.5" high, 17" wide, and 2.5" deep, with a baffle designed for controlled directivity. It is
