I have been using my BRX speakers and forcefield 30 sub for stereo music but thinking about a home theater setup. The goal for the center channel is dialogue clarity. Am I better off with a SuperCenterX or a SuperSat.50C? My room is 18 by 12. Seating and system on opposite long walls. Will be using the new Onkyo RZ30 with Dirac built in correction

Hi Olde, First, either the SuperCenter X or SuperSat 50C would work well as the center channel in this system. Both models are tonally matched to your BRXs, and both models sound clear and detailed. Given a choice, however, I would lean toward the SuperCenter X. Overall, the SuperCenter X sounds a bit fuller and richer than the SuperSat 50C. If you can physically use a SuperCenter X, that would be my first choice. Happy Listening!
