I had an awesome purchase experience at Sam Ash in White Plains NY. The sales agent in the keyboard dept (sorry I can't remember his name, but he works evenings, and I think he was the manager) was excellent, and very knowledgeable. He answered all of my questions about pairing these studio monitors with a mixer. The sound these monitors make is amazing, with a great mid-range and high. I've heard some people say the base wasn't low enough, but for what I use it for (the guitar) it's perfect.
