Upgrade path?

Orienting the Duo vertically will allow for seats off axis to more closely resemble the sound on axis. If that matters to you and you have the space then absolutely orient the speaker vertically. If you only care about one seat on axis then it probably won’t make much of a difference.

Technically the vertically oriented speaker should also yield better performance directly on axis since the off axis reflections should more closely resemble the on axis sound. I think this might be a pretty small difference that might not be all that noticeable though. It is easy for you to try for yourself and see if you hear much if any difference though. That is the best thing to do here. Switch it for a week and see if you like it.

Good post... explaining the probable outcome implementing design traits of CC.
David alludes to over reaction and general mis understanding of lobbying issues with MTM designs...in another thread. How auditable remains a question...but one must take the full listening window into account vs. a single perceive metric slightly off axis...to make an informed decision.
