7.1 refers to the number of speakers meaning 2 front speakers, 2 rear speakers, 2 speakers placed in the middle of the room at the side and 1 front centre speaker while the ".1" refers to the subwoofer. Since the digital audio signal transmits better thru wires than wireless, he did up his wiring thru the plaster ceiling and had the ends located at 6 sides of the room, and originating from the front. Then he had his hard disk player placed into his laundry room which was behind the AV room; there was an opening in the wall. Looks like I should get his feedback and ideas for my own setup.
Thanks for clarification. Cos over here there is this so call invisible speaker really plaster to wall or ceiling. tot I wanna find out feedback on performance
