Product description:

KEF R11 Hifi is the largest model in the R Series combines four bass drivers and the latest generation Uni-Q for a powerful and refined sound.
With hybrid aluminium bass drivers and a 12th generation Uni-Q for mid and treble the mighty R11is extremely capable.
Using technology from KEF Reference it delivers clarity, finesse and serious bass.
Each of the four 6-1/2″ hybrid aluminum woofers is made up of a shallow aluminum skin atop a paper cone.
This hybrid design allows very precise movement, for dynamic, accurate bass.
