Actually a second EP600 is still on the list of additions, just that the Halo system killed the budget for a time, not sure when I will be able to have it arrve. Mayb e a x-mas present from some nice person that feels sorry for a lonely subwoofer in need of a brother. I think two of them side by side would look very impressive, and match the pairs of rear M80s and QS8s one sees when entering the family room.
