Hi jbsengineer,

Good suggestions from all, and I concur with Jakewash's suggestion to mount the left side surround on the half-wall. You could move the right side surround forward a bit over the sectional and add a one or two back surrounds (for 6.1 or 7.1, respectively) to achieve really excellent envelopment.
