I have always heard about the famed Bose 901 series. Happened across an ad on craigslist for a pair for $60. I called the guy to make sure it was legitimate - it was and they are now sitting in my living room. Nice, but at first listen do not compare to 12B's. I'll need more listening time and some tweaking with the EQ but so far, I am impressed, but not as impressed as I with the 12B. I will say there is FAR more bass than I expected!
