I truely do hope that Klipsh does decide to offer a 5.1 system sometime in the near future. I am very impressed with thte speaker system, and I bought them before most people even knew about them. However Dolby 4 channel surround sound in no way compares to dolby 5.1 or even dts. I love these speakers but there is so much more to be heard in a true 5.1 system, not just the center channel. Please Klipsch I am begging for 5.1
