It’s 11:00 on a Sunday night. Your honey just went up to bed and you can’t wait to crank up your latest Blu-ray acquisition: Jimi Plays Berkeley, a long-forgotten 1970 documentary that has been restored and remixed in 5.1 surround. Seconds after Hendrix rips into the first number, the dreaded foot stomping from above begins. The party’s over before it even starts. Last time it was a cataclysmic crescendo from Inception that did you in. Frustrated, you vow to remedy the situation and, once and for all, soundproof the family room that doubles as your home theater.
