Every room is different. When you own any new speaker you have to play with them and learn how they work best in YOUR room. Take them back 6" and listen, use a recording with standup bass, listen for the changes in the bottom end. I use the Chesky System Demonstration disc. This has a stand-up bass track, a Sax track, one with horns and drums, and vocals. In one disc you have all the music you need to hear changes, and toe-in is another thing that is room dependent, 1/4" toe-in at a time, once you get a solid center imaging using a true mono recording, get that right the stereo image will be great. Another thing look at your room acoustics, which plays a major part in your sound quality. Clap your hands if you hear ringing, well that means your music is also.
