The RF-3II were great in their time and for the money. I have a basement full of Klipsch speakers. I have a pair of RF-5s and a pair of RF-3II a RC-3 center and a KSW-12 subwoofer. I have been trying to sell for 600.00 total, so far no buyers. I live in Louisville, KY.
I found the 3's to be in the box compared to the 5's sound. The xover is superior in the 5's as the horn. Klipsch has a undeserved reputation of being bright and brash, which they are new. They have a long break-in period so a 8 year old Klipsch may be a blessing. Somethings Klipsch speakers do better than any other, such as piano. A lot of rock n rollers used the La Scala's in the old days.
I can't say whether the price is good or not since I can't seem to fire sale mine.
