Thanks for the detailed response. I did get around to making the 120 mile round-trip, but I hadn't envisaged that the speakers would be so huge - I had noted the measurements on the Klipsch site, but just didn't picture them being so big. Anyways, the speakers are missing grills, the floor risers (they were simply resting on the cabinet itself - is that going to be a problem on a tile floor??? If so, could anyone offer any recommendations?) and have significant scuffs on the cabinet, but they sounded good even though they were being driven by a Yamaha A700 and a portable CD player in a garage standing almost next to each other (I am sure that it is not the ideal setup I was definitely impressed with the sound and so I have to go back this weekend in a more suitable vehicle to pick them up.
I was told that the driving these at high volumes can damage the tweeters which are extremely expensive to replace. I used a flash-light to look at the horns and tweeter on one of the speakers seemed to be caked with a layer of white dust - the owner said that these speakers were set in a wall in a previous HT application. Are they easy to open up and verify that it is just dust or should the speaker have sounded bad on high freq. with a blown tweeter and hence immediately noticeable?
Finally, the seller has dropped the price to $500 for the pair - does that sound reasonable for the condition?
When you mention a caustic review, was it for CF-4's in general or their later iterations?
Also, I know that I have asked it before, but if anyone has any experience with a NHT VT-2 and how does that compare with a CF-4, I would greatly appreciate that - I have an opportunity to pick up a pair of NHT's for around $400 and NHT's have a smaller foot-print and I think a greater WAF (I don't have the luxury of a basement in South FL and hence the HT is smack in the middle of living room). So, I would appreciate any insights.
