Woofer on top?

This was always Missionaries position but it works quite well either way.

It depends on the crossover design as many will create a lobing of the on-axis response up or down. Of course, you want that aimed at the listener's ears.

Sorry, it is not the woofer that is on top, but the tweeter that is on the bottom!

My wife has a pair of tse smaller Missions with that configuration and I can't see that it changes anything, assuming the speakers are on stands and at the correct height.

BTW, what ever happened to Mission are they still in business?

Many Mission models to include the M70, M71, M72 have this design and sound fine. No hard and fast rules with tweeter placement.
