Can anyone help, I am setting up a suround 5.1 system in a large room 6 x 10m. I have to use small speakers but the size of the sub is not so important. I have the following on the short list. Kef Eggs. JM Labs Sib Cub. Elac Cinema 2. Energy 5.1. Are the Kef's and JM's worth twice as much as the others? I will be using a HK 2550 or Yamaha Dsp ax630, will be trying this week but would like to make the speaker list shorter before the demo. I only want 5.1, so should I go for the ax620 which is cheaper? Any help will be appreciated, Thanks.
