Just some brief thoughts from about a 30 minute listening session...
On saturday I demoed the klipsch rf-25, rf-62 & rf-82.
They didn't have the rf-63 and I didn't have the time to listen to the rf-7 & rf-83.
Store server demo songs: Eagles "Hotel California" (live)
CD songs used: Cake "Stickshifts and Safetybelts", Liquid Tension Experiment "Paradigm Shift" & Joe Satriani "Train of Angels"
DVD video concert songs used: Eric Clapton's
One More Car, One More Rider "BellBottom Blues" & "My Fathers Eyes" (5.1 setup, Sorry but I forget what model center/surrounds/sub...My bad!)
The rf-25 is nice. The rf-62 is better. Smoother but high end is really the only big difference IMO but they still have that "Klipsch" sound alot of people love. The rf-82's has alot more bass as would be expected and the mid-high end had more depth then the rf-62's. (same tweeter and horn but silghtly different crossover 1800hz for the rf-62 2000hz for the rf-82) They all had a recessed mid range that I found a little dissapointing. Lacked the lively detailed response
I was looking for. Billy Prestons Hamond organ on "Bellbottom Blues" lacked that classic reverb that makes the Hamond a Hamond.
I have really focused in on mid-range reproduction lately so i may be overstating a little bit, but to be fair it could have been partly the rest of the 5.1 set-up (very small surounds) and I am sure all the crossovers were not set properly. I usually need to listen to a speaker 2-3 times to get familiar with it so...
I wish they had the rf-63's on display I really think for me they would have been the best speaker of the lot. I wonder if the mids would have been better.
1-1/4" tweeter with a 1700hz crossover instead of 1" in the fr-62 & rf-82 with the cross over points listed above.
IMO they improved the middle of their reference line up with better high freq. response and the Klipsch faithful should be very happy. I will go to a different store and give another listen soon. If my experience changes I let you know.
Take care,
