It appears KEF has changes in mind with the Q series. Currently on
KEF Direct it appears they have significant discounts on most of the popular Q series speakers.
By clicking on the link embedded above, you can see about 30% off on Q100 & Q300 bookshelf as well as Q500, Q700 & Q900 floor standing speakers. Of note is that the matching Q200c & Q600c center speakers, Q800ds di-pole surrounds and Q400b subwoofer aren't included....yet.
If you wanted to expand your current Q series or get the next bigger ones, now's the time. I'm curious to see if they do an update to the current design or introduce something completely new.
