I have the original Sierra 1s sitting around. They were replaced years ago with the Towers. I've considered putting the Sierra 1s in my office recently. I would use them for light mixing and casual listening. The room is not that large (12'x15'). Has anyone used the Sierra 1s in such an application? Also, I would not have a ton of room between the rear of the speakers and the wall. Am I better off buying a pair of studio monitors? If you have been able to make it work with the Sierra 1s, what amp/receiver have you used to drive them? This would be music 2.0 only application.

Thanks!
