I warned you my advice wouldnt be worth much. Looks like 2-cents was overselling it some what.
I guess it depends on the rears. I personally use some old but very capable M+K tripoles. Hardly point source speakers.
I can imagine echo effects mixing EBA across the fronts, less so with rear channels.
Anyho, dealer really should be the first point of call for this sort of question IMHO. Asking here will probably just be adding noise.
Let us know what they sound like though, especially through a v8 should be really quite something.
Cheers
