I wouldn't mind co-locating two EP800s on opposite mid-walls, but then it kind of defeats the justification for me getting two more EP800s. I was keeping the horizontals in anticipation of using them on the front and rear walls, where they would fit the best. The verticals, on the other hand, work better for me on the side-walls. If I was going to co-locate, then I would want all four as verticals to be placed on the side mid-walls. I suppose I'll try out both configurations and see how it plays out. If I end up wanting to keep them co-located, though, then the holes for the feet on the horizontals might bother me. I guess one way around that would be to have the horizontals laying down like they're supposed to and then have a stand of some sort elevating the verticals above them. Ha ha.
