Yea, Im a school techy and that is a pretty good setup. We have Yamaha speakers and they seem quit reliable.I think the speakers we have are like a model or two older then the ones you got. And there is nuthin wrong with a wireless, they are soooo much easier to use.
It should be a pretty sweet set up for what your doing. Not bigenuff to need a set up that costs more then what you got.
