I have had the R11 non-meta for about 2.5 years. I did pair them with a Rythmik F12SE, but they have great extension and sound on their own. Perhaps the best bang for the buck out there.
The only reason I am selling them is a pair of KEF Reference 3’s were available for local pickup at a price I could not resist. It’s actually amazing how similar in sound the R11’s and Ref 3’s are, with a $9K difference in retail.
Go for the R11’s, you won’t be disappointed!
