About the Spatial Audio M3 Triode Master
The Spatial Audio Lab M3 Triode Master is a two-way, dynamic open-baffle loudspeaker with controlled directivity. It uses two 15-inch paper-composite mid/woofer drivers and a coaxially mounted 1-inch M35 dipolar compression driver. The speaker has an in-room frequency response of approximately 32 Hz–20 kHz (±3 dB), sensitivity of about 93–95 dB, and a nominal impedance reported as 16 ohms with a low phase angle. Its narrow open-baffle enclosure measures approximately 42.5 inches high, 17–17.5 inches wide, and 2.5 inches deep. The design is intended for use with low-powered amplifiers, including suitable tube amplifiers, and is known for broad, controlled dispersion and an expansive soundstage.
