Forty-eight MacIntosh MC-2300 amps producing 28,800 Watts of continuous RMS power (48 x 600) that drove 586 speakers and 54 tweeters. The bass rig had a separate amplifier and speaker array for each string! The Grateful Dead's 'Wall of Sound' didn't last very long, but it forever changed the way we listen to concerts.

Combining exceptional engineering and unrivaled vision, KEF's engineers have developed a brand new approach to subwoofer performance.  Using KC62's force-canceling and Uni-Core technologies, KEF has revolutionised traditional expectations of what a subwoofer can achieve based on its size. Measuring at 9.68 x 10.07 x 9.76 inches, and weighing 31 lbs, the new 1000W KC62 subwoofer delivers unprecedented depth and breath-taking accuracy with its compact and sleek design.  This is a result of the patent-pending, ground-breaking Uni-Core technology.
