Most dedicated home-cinema speakers use di-poles for the rears to "simulate the speaker arrays from a real cinema setup". That got me thinking - why simulate? Why not run (at least) 2 smaller monopoles for each surround channel. Apart from the obvious issues of space & cost! If one does have the space available & chooses to run 2 smaller speakers for the surround (side) speakers why not? So two speakers will be running the same channels (eg. surround left) - do processors have 2 pre-outs for every channel (to power 2chans of an amp)? Also: in a real cinema is there a delay (or any other processing) between one speaker and another in the same array? How should this be physically setup relative to the lisening position? Should the 1st speaker be in-line with the listening position & the 2nd behind? Or maybe one infront & one behind? Any opinions appreciated.
