So what is the best speaker you have ever owned?


I would like to know what the best speakers in any system that you have owned personally, not just listened. Specifically, what characteristics made it better than anything else? (imaging, bass, dynamic range, smoothness, size, looks, distortion, how it moves air, price, etc.)
thanks, Nita

ESP Concert Grands and Genesis 350 SE (also really liked Coincident Total Eclipses).
This is a record, I believe. It took 27 responses before an answer was given stating that the answer is relative. I'm not saying that it isn't, just that it's rare for a discussion to go this long without it coming up.
My current Soundlab A1's with Hotrod backplates. Not heard a box speaker as magical as these SL's! Silverline Bolero's are second place...
My current ProAc Response 2.5 pair. The best thing about them? I forget about them completely while music of all kinds, from the 20's to today, raises goose bumps every day. On a smaller scale, the ProAc Tablette 50 Signatures in my second system have the same quality.
