Yup. Definitely thinking about buying used. I am however somewhat scared of buying something used and then finding out later that it doesn't meet my tastes but maybe I will take the plunge.
I don't blame you. I would be too. But why limit yourself to being scared in taking a plunge with only used? The same applies to new also. Unless you can hear the speakers, you really have no idea if any of them will suit your tastes. You now have close to thirty suggestions (myself included) and are you any closer to finding the best speaker with a small footprint under 2K?
There is no best of anything, especially loudspeakers. There is only what is best for you. You must now make an effort to go out and hear some of the speakers that were suggested for yourself. You may hear some that weren't even mentioned in the thread and find out these were the right ones. Your amp will drive most of them so no worries here. What your doing right now is akin to selecting a vacation destination, while blindfolded and throwing darts at a map. Good luck with that!
