Re: Would I be able to hear these?
I would think at 200W as a monitor near you to begin with, this should be enough.
However, I haven't heard anything about this Harbinger company or heard their products in a real situation.
The good thing is it's the Guitar Center, you have 30 days to see if it works! Let us know how it is.
I myself, have a rack with two Crown XLS amps: one powers two Yamaha A15 speakers as my mains, and the other powers two Peavey Neo 12 passive speakers. This I consider the absolute minimum for my requirements.
