SpeakerCraft traces its roots to 1976 in Riverside, California, where audio enthusiasts Ken Humphries and Ed Haase opened a small stereo store amid the hi-fi industry's explosive growth. Driven by a passion for music's emotional power, they experimented with speaker designs that captured local acclaim. By the early 1980s, their breakthrough flush-mount in-wall loudspeaker revolutionized architectural audio, launching the self-branded SpeakerCraft line in 1994 and propelling the company to industry prominence.
The brand specializes in custom installation solutions, excelling in high-performance architectural speakers that integrate seamlessly into walls and ceilings, alongside amplifiers, control systems, and multi-room playback products. Designed in-house by top engineers using cutting-edge technologies and premium materials, these offerings support diverse sources—music, movies, TV, podcasts—while prioritizing bold sound and designer aesthetics for whole-home immersion.
SpeakerCraft holds a respected position in the custom integrator market as a high-end innovator, favored for nearly four decades by professionals seeking transformative audio that elevates everyday listening. Its lifetime limited warranty on speakers underscores enduring reliability, cementing a legacy of turning houses into sonic homes, even as its heritage influences successors like Origin Acoustics.
