And I forgot to mention, what I'm most impressed of, is my pair of Genelec 8010. A really HUGE sound for their tiny size and only 7 lbs per pair. And of course premium studio monitor sound quality. They are stated to go down only to 73 Hz, but the bass sounds much deeper. No distortion of piano sound even at high volumes. It's bizarre: Some years ago I tried the bigger Genelec 8020B - they did distort with piano sound. These small ones don't - and they are much better than the former 6010. Just one small inconvenience: they require XLR cables.

P.S. I'm going to make a video demo of them some time.
