About Us

Since 1973, the Intermountain West has turned to Phase 4 Stereo for all their audio needs. As one of the nation’s largest independently owned electronics dealers, we carry the same quality products as the big box stores but with the friendly, helpful service that only a family-owned business can provide. From stunning home theaters to commercial audio systems, we offer a wide selection of the latest speakers along with quality installations. We’re proud to be Idaho Falls’ stereo experts, and no matter what your audio needs are, we’re here to help.
