I currently have a set of Paradigm 5seMk3 speakers that I enjoy, I have an opportunity to pick up a pair of 11seMk2 for what I believe is a reasonable price but I can't find much info comparing the Mk2 with the Mk3 line. Does anyone have any experience with both these lines of speakers that can shed some light on various questions such as different component materials, equipment design differences etc, and whether this would be considered and upgrade or not? I know my ears will help in the final decision, for now I am looking for other people's opinions on these speakers.
