Why so many used focals?

There's an old saying in engineering Steve, "If it looks right -  it usually is".The Kanta 3's look right. I don't know why, but rear ported speakers are a game breaker for me. The Kanta 3's are front ported, and look at these numbers. Sensitivity 91dBFrequency Response (+/-3dB) 33Hz - 40kHzLow Frequency Point 26HzNominal Impedance 8 Ohms26Hz pretty much gets any job done, 91db with a nominal Impedance of 8 Ohms .... so they're not that hard to drive, two 8" drivers give them good weight, an inert cabinet, and they're decoupled from the room because of the speaker stands; I'd say you have the foundations of a speaker here that should give you many a year of listening nervana - - - at least on paper. (Mind you the proof in the pudding is in the actual listening).You're right to take your time .... they'll be making them for awhile.

I'll check but I think they're ported front and back. I couldn't pass on a pair of Usher BE-20 DMD Dancers that came up locally and am really having fun with them. It never ceases to amaze me how much impact a room can have on sound. I had a pair of R 107/2's down here, the ones with 2 10" woofers inside the box eq'd to be flat to 20 hz and vented out the top, even those speakers loaded my room with decent bass tho' overall the tweeters turned out to be a little bright for my taste. I have no engineering background or prejudice to speaker design just what works in my room. 

^ Good find. Rest assured you chose well - much better speakers than what Focal produces at that price point.

Any speaker engineer worth his/her salt knows that a front port is more likely to produce audible port noise when playing near its limits. 

Thanks helomech, the seller said his inbox exploded when he listed them and I was the first to offer pick up with cash in hand, after last nights listening session I believe him. I still want to hear the dyn C60 and Kanta 3 down here but i'm not in such a hurry now. Thanks for everyone's contributions.

The old engineering saying that if it looks right it usually is, is usually wrong. That thinking produced lousy aerodynamics on cars. It produced a lot of lousy speakers, especially in the 60's and 70's. It's produced plenty of architectural and structural failures. Good engineering hardly ever produces things of fine esthetic beauty.
