The BasX A11 is a great choice if you're looking for a high quality power amp to pair with a pre/pro, like our MC1, to power all of the speakers in a 7.1.4 channel system. And, because the A11 provides so many channels of amplification in a single chassis, it also offers some other interesting options, like providing the channels you need to enable you to bi-amp the three big front speakers in a formidable 7.1 channel system.
