I am looking for my first center channel and have read about voicing it to match your left and right speakers. How do you do that? I have a 4 way system with 10" Hartley woofers, 4" Eton mids, 7" Hartley tweeter and Beyma super tweeter. I have access to more of these drivers but am trying to see what I can get that will have a smaller footprint for a sealed box. Thanks
