This completely changes the meaning of portable speaker.
Using old suitcases, Dominic Odbert in Sacramento creates one-of-a-kind speakers, CNET reports.
Odbert's has a background in fine art, and he's been building audio gear since he was a kid. Odbert and his small staff hand-build all of the BoomCases, and Odbert likes to use suitcases from the 1930s or 1940s, though he also uses more recently made suitcases. Odbert reinforces and cross-braces the interiors of the cases. Ever since Odbert started BoomCase in 2009, he has made sound quality a top priority. He uses very efficient Class D amplifiers sourced from a small California company, and he gets the battery packs from an Oakland supplier (BoomCases can also be plugged into an AC power outlet). The rechargeable battery runs for more than 10 hours on a charge.
Most old vintage suitcases are made from wood, which Odbert says helps produce a rich sound. He hand selects woofers and tweeters, but says he uses many new Sony and Pioneer drivers. The BoomCases come in mono and stereo.
