Innovative Engineering + Dual Concentric Driver + SuperTweeter = Magical Sound.
Take a close look at the new Tannoy Sensys DC speakers. Notice anything unusual? Anything at all? I suppose that little gray pod sitting atop each speaker will catch your eye first. It's home to a SuperTweeter that's designed to extend the speaker's response out to a range that only dogs and bats can hear, claimed to be all the way up to 51 kilohertz. Look again and scrutinize the 7-inch woofer with bull's eye circles in its center; that's another, albeit standard, tweeter. Tannoy dubbed their "tweeter inside a woofer" design as Dual Concentric, a hallmark of the company's upper-end speakers that dates back to (gulp) 1948. Dual Concentric is a really big deal because it generates minimal off-axis phase shifts over its nearly full-range frequency response: High and low frequencies originate from the same point. The Dual Concentric breakthrough led to a range of legendary speakers in the pro audio and high-end markets for more than half a century.
