I'm considering making a trio of Eros, for my front LCR in a future dedicated theater. I don't know what I would do for surrounds though. I don't want to use the expensive Vifa/Scan Speak drivers for surrounds, it seems like it would be a waste of their talents (and my money!). Its practically gospel that the drivers in the front three speakers should be the same, but is it true for the rears as well. Will having dissimilar drivers in the rear cause front to back panning to be disjointed? I'm not sure. Anyone have any opinions/suggestions/cold hard facts( )?
