Prime, no doubt, you are entitled to your opinion and for the most part I agree with you. But it is all about preference. I own RF-35's and my room is 18 x 11.6 x 8.
...If the RF-7 and 7II owners believe that using those speakers in their small to moderate sized rooms is justified, then so be it. And I have listened to RF-7 series speakers extensively and no doubt excellent speakers, but to me, not justified for my room size.
My Klipsch Library Home Theater is in about the same size room but I have a higher A-Frame ceiling for most of it. That said, I use RF-3s (comparable to your RF-35s} as side surrounds. They used to be my main speakers and there is no way they have the sound quality of the RF-7s/RC-7, but work great with my set up along with RB-75s in the rear and 2 RSW subs taking up the lower end...That said, appreciating Home Theater has been my Hobby for 13 years. In the beginning I compared speakers to the point of mania and for most of the last 8 years I consider Multichannel Music as my hobby.
I completely understand you being happy with your Klipsch Home Theater but wanted to give a second opinion on why some of us are motivated to purchase upper-end models that may not justify the cost (or time consumed comparing/auditioning) to others.
Zen, I appreciate your perspective. Hey, I would love to have a pair of RF-63's. As a matter of fact, there are a pair on Audiogon right now. And guess what? The seller resides in Texas! Being that I live in Delaware, according to the seller's description, shipping is not an option. That's too bad because the asking price is ridiculously low. But here's the thing, as much as I would like to have them, because I am familiar with the difference in sound signature produced by the 3 driver array and different crossover point, the difference doesn't make me want to drive to Texas and pick them up. But, don't get it twisted, if the owner were wiling to ship, then I would consider them.
