I enjoyed reading your review. I am glad to see that Klipsch is receiving respect on these speakers, in particular the updated horns. I too would love to see a comparison with the RF-7ii. Based on your review, I suspect the overall sound character and timbre would be similar.
In regards to the RF-7ii - I have an RF 7ii system with Klipsch THX ultra2 for the surrounds that I use in a dedicated home theater. I have had this for about 6 months now. I use a 200W x7 amplifier by Lexicon. I listen to 90% movies, 10% music. I have not had a problem with ear fatigue to the horns with this system, maybe because of a good clean amp. Also I have the speakers behind the screen which does probably cut the highest treble down a bit. In fact, I purposely tweaked / boosted the sound in the higher frequencies due to same. I will say that after watching a movie like Gravity (i.e. the heartbeat subfrequency sounds in the beginning), I have developed some listening fatigue to the subwoofer bass (I have 2 subs) and have had to dial it back during the movie, but I suspect this is due to a bass peak due from a room mode (which I am planning to treat) or maybe because it has a separate amplifier which is not as clean as the Lexicon amp.
Before I purchased these speakers, I listened critically to numerous speakers, many of which were more expensive than the Klipsch, and I chose the RF-7ii for its sound quality and clarity across the spectrum and for its performance to value ratio. Also, as a side note, after watching movie demos in a showroom, I preferred the dialog from the center channel of the RF7-ii series (the RC-64 II Center Speaker- horizontally mounted behind the screen) over a 3rd vertically standing RF7-ii behind the screen.
Keep up the good writing.
