Larry; Thanks again bro.
re: "For sides that are in additional to the stereo rears, they should be reproducing what is common (L + R) to the front-left and rear-left channels, to avoid the 'hole' effect from there being no speaker directly to the side; that's why *4)the surrounds should be to the sides when adding a rear-center."
Am I right in understanding:
1a)for the left side mid speaker = what is common to the Front left & Rear left AND
1b)for the right side mid speaker = what is common to the Front right and Rear right.
2)If so how is that extracted & with what equipment?
3)I wonder what the Yam front effect (+2) speakers extract?
re:"...centre speaker.. surrounds to the rear sides"
*4)I have put the centre 5' behind the rear the rear L&R I put to the back OUTSIDE of the listening area
pointed in at a 45 degree angle (essentially the same as my front L&C&R speakers. I think except for (+2)'s all 6 of my seakers are direct radiating ? Dipolar?
(still haven't got the mono/di/bi/tri polar figured out & the direct radiating & what ever else there is)
The Kenwood's are "front imaging" but were not for rear side surrounds - they were matched with another model.
