Csi5 Wall distance

gurot1

I am using rti10's and csi5 upfront. The speaker backs are about 19 inches from the wall. That's about as much as I am 'allowed' to move them out. (as an aside, do u ever notice the nest of cables behind the receiver when the speakers are pulled out front!). I might move them back towards the wall a little as they are ten inches in front of the tv which is on a swivel wall mount and it is looking kind of awkward and the centre seems too far in front of the tv. What is the recommended minimum distance the csi5 should be from the wall? I hear the rti10s should be about two feet from the wall. Thanks
