The new range of Vibe Slick speakers are the most efficient Vibe speaker to date. The woofer features a super lightweight paper composite cone and foam surround, a single layer spider and perfectly balanced voice coil. The secret weapon is the incredible range of tweeters, a 50mm tweeter on the 5.25″, 5″ x 7″ and 6.5″ models and a 40mm tweeter across the rest of the range. This provides an extended bandwidth and high level of efficiency. The component tweeter uses high end components and is one of the smallest on the market, but packs a huge punch, causing Car & Hifi magazine to call it a force to be reckoned with as it provides great detail and good spatiality.
