More info and I like the choice, although I have occasionally caught some rather big horns beaming once in a while, in a smaller room. Not so different from my JTR T8, which also are
total overkill for a small room. But rather fun tactile-wise.
So how far off a wall do they need to be mounted? I see dual rear ports but I also see they stick them rather close to a wall, in the manual. Ideally one should want the speakers to be 6" off the
backside of any woven AT screen material, to avoid timbre shifting. Lots of information to work with there, to come up with an ideal, but minimal AT space depth, to reflect the depth of the room.
And with a 60 degree speaker spread, that helps to establish screen width when combined with room depth and looking at room depth for ears, to that have smoother audio response.
I'm not exactly sure how those rear ports will mesh with front wall treatments, that will be needed to suck up the energy coming off the backside of the AT screen. But you will want to absorb that, so
that might mean a bit more AT space depth potentially there, then the common 2". I also am not familiar with the 590's so how do the port plugs work, and are they a tool to be used? I expect you
reduce their bass depth, or output, but that might still be a good option with flexible crossovers in the avr and depending on the sub.
Quite a bit of information right there, from one piece of unknown gear. That's a pretty good example of why take the time to ask about something, because the room depth coupled with a properly designed depth
of AT space, could rule out the choice of an AT screen in such a depth.
