Introduction
KEF is the venerable British-based loudspeaker company founded in 1961 by former BBC electrical engineer Raymond Cooke. The company first became famous for its monitors and Reference series speakers. In 1988, KEF introduced the revolutionary Uni-Q system, which mounted a neodymium-based tweeter in the center of the woofer voice coil. Since then, KEF has expanded its product line to include the ultra high-end Muon down to the entry level C Series speakers. The subject of this review, KEF’s Q Series speakers, is the next step up from the C Series. As the name implies, it offers the Uni-Q technology in each of the five main speakers.
KEF also provided its new HTB2SE-W wireless subwoofer, which won the design and engineering showcase honors at last month’s CES. The HTB2SE-W is a radical departure from the standard rectangular box design, and as Secrets’ resident bass-head, I was excited to check it out.
