About the Triaxiom 15"

The Goodmans Triaxiom 15" is a vintage high-efficiency loudspeaker driver made in England during the 1960s and early 1970s. It features a 15-inch gold-colored woven paper cone with an accordion surround and a horn-mounted tweeter in the center, designed as a coaxial driver for wide frequency response and clarity. The speaker is known for its robust construction with a massive diecast chassis, extra-long 3" diameter voice coil, and large Feroba II magnet. It has a nominal impedance of 15-16 ohms and a power rating around 30 to 50 watts, making it suitable for low-powered tube amplifiers. The driver is highly sensitive, with quoted sensitivities around 95-100 dB, and is praised for its transparency and durability, with surrounds that rarely deteriorate.

The speaker is considered collectible and can be found on the secondhand market, often
