Hey everyone I have a question on the following set up is. The reciever is a Yamaha RX-V1800 (6190B) Originally I had planned to pair this reciever up with the Energy Take Classic 5.1 set. But I think I would get better sound if I went with Velodyne Subwoofer (DSP-12B) 2 X Klipsch Synergy Tower Speaker (F2) Front 2 X Energy Bookshelf Speaker (C100) Rear But I noticed that the second setup does not have a center-channel speaker. Would a center-channel speaker be required or would the 2 towers suffice? Should I just stick with the energy classic set? Thanks in advance
