I finally got to correctly set-up my pair of unmodified SL2000 CRS+ yesterday with a good amp (6' apart and on stands 3" from the back wall), and they are great speakers. The detail is unmatched, as is the sound quality and the imaging. I put on Bach's Toccata and Fugue in Dmin, and I have never so clearly been able to see all the different pipe and the expanse of the church in front of me. It was quiet and experience and I will be enjoying it again after work today. The bass was also quiet impressive for such a small speaker. Not the SPL of floor stand speakers obviously, but better than I would have expected; I guess thats why I have a pair of subs to go with them. My only issue with them was the vocals. They were very clear and sounded good, but were recessed to parallel with, or behind the speakers; even sometimes behind the instruments. I didn't expect this at all as my SDA 2As project vocals forward very well, as do even my Mon. 5 Jr+. This is the only pair of Polk speakers I have seen this in. Like I said, it didn't necessarily sound bad, it was just more recessed then I would have liked, and it was only the vocals. This week I'm going to start the 4.1TL mod with all new caps and resistors, but I wanted to hear these before I modded them so I'll know what the change sounds like. I hope the 4.1TL might address this a little, but it was just a surprising find in the CRS+, and a little disappointing.
