The design of the MC501 is straightforward and extremely burly. Not only is the amp capable of delivering 500W into any load between 8 and 2 ohms, it's also rated to deliver more than 100 amperes of output current. It seems exceedingly unlikely that there is a speaker that the MC501 could not drive.
