surround system

hi y'all

Im extending my rig (currently 2 stacks of JBL, each 18W, 15 horn, 2x12, 2+2 bullet powered by 5k of crest) with an extra pair of 12 or 15+1 cabs with the idea of using them to produce spacial information and FX. The current plan is to build a simple decoder (something ala hafler probably - combine out of phase L+R signals and use result with a c20ms delay for rear left and (probably 180 degrees out of phase) rear right)

Im also planning a controller to move a mono source anywhere spatially within the mix (current thinking is to use 2xVCA balance circuits controlled by 2 faders mounted at 90 degrees one above the other with the whole assembly mounted on runners to allow free movement L-R and front-back simultaneously - difficult to explain what I mean clearly but would welcome more elegant ideas)

Im looking to use a 16:4 desk + dj mixer to control it all - with a small patchable FX rack just to further complicate my life

Has anyone tried this sort of thing - any tips would be gratefully received, also if anyone has space in/around london for a slightly unusual chillout (lighting/visual plans are equally convoluted too) then please drop me a line

Sounds good, how about using a chopped up PS2 Analog stick, or do you want it hold the position?
