Is there a good set of speakers for a 7.1 home theatre system? All the group sets I can find consist of 5.1 systems. Are the Klipsch synergy 6 series any good? Looking for under $1000 for a dedicated home theatre room about 16 by 23 feet. Will be getting a 7.1 thx certified receiver at least 100 amps per channel x 7. Suggestions?
