The Grateful Dead is celebrating its 60th birthday with a new release of speakers in collaboration with McIntosh. The RS150 and RS250 wireless loudspeaker systems are dead-ified versions of McIntosh's popular models. These speakers pay homage to the band's innovative "Wall of Sound" system from 1974, providing fans with clear, distortion-free sound. The new Grateful Dead x McIntosh speakers are available for purchase, with the RS150 priced at $1,500 and the RS250 at $3,500. Fans can also see the RS150 on display at the Sphere in Las Vegas during Dead & Company's residency.
