First off, Pro Studio speakers are not meant to be used as sound reinforcement. They will go louder than most home audio speakers, but the drivers do not have as high of tolerance as professional grade sound reinforcement speaker systems.
Second, a receiver, especially one as puny as the Insignia, will not do well in a high output scenario. I'd recommend getting a Behringer A500, more powerful than the receiver, and it will fit the application and the speakers. If you put a more powerful amp on those speakers you run a risk of damaging the speakers.
