I went to Guitar center (in store) this past weekend and bought my first set of monitors.. a pair of mackie mr5's on sale for $99 each....Got home and ONE of the monitors have the MACKIE logo on it, and the other has the OTHER mackie logo (looks like a running person or whatever..cant really explain...i will provide pictures if needed) but what are the differences between those two models, if anything at all? if there are differences im def going to demand them to send me the right one...
