Yeah, I suspect its more audible for midrange that the bass is behind, reflects and diffracts, and would think that typical stacked configuration would have less audible issues, on any of these. Luckily the system is relatively easy and cheap to prototype so any downsides can be audited, use which ever seems to work better. You might find out there is not too much audible difference, and some other aspect on the build would help making decision.
