Hi everyone. Well I finally shelled out the 300 bucks to buy the 4.1's today. I do have one problem though. The lead speaker (the one with all the controls) seems to have a loose "object" rattling around inside of it. When I turn it on its side or upside down, I can hear something (be it a component or whatever...) rattling around inside of the casing. Has anyone else had this problem? What exactly is floating around? Will this affect the speaker's performance? I have nothing to compare them to so it's difficult to see if they're working up to their full potential. Thanks a lot guys.
