Those towers do appear a bit short, as the tweeter is ideally placed around ear height. However, not only are they close together, but also toed in.
To be clear, are we worried about one seat sounding good, or multiple? Cause I guarantee each seat will hear two speakers, not one like you are supposed to. The goal is one stereo image, not multiple. So if you can listen and pick out each speaker individually, the room layout HAS to be changed. Otherwise a Sound Bar is your best alternative.
