“Like almost every hi-fi speaker now made by KEF, the Q750 is based on their Uni-Q driver technology. Uni-Qs are coaxial drivers; each one comprises a tweeter operating inside the cone of a midrange or midrange-woofer driver. This is done so that the soundwaves generated by the two drivers emanate from the same point in space, to make their combined output a “point source” of sound. (Only KEF’s lower-priced C models still use discrete tweeters and midrange or midrange-woofer cones.) The Q750’s Uni-Q has a 1” dome tweeter and a 6.5” midrange-woofer, the latter left unfiltered on its low end, to extend its output as low in the bass as possible. To add to the midrange-woofer’s bass to increase extension and output, the Q750 also has a 6.5” woofer augmented by two 6.5” passive radiators.”
