Curious as to the thoughts of what the various speakers/mountings would sound like for the fronts?

Focal 165KRC in a modded speaker pod
Focal 165KRC mounted in a BT bracket
BT 7.1 mounted in a BT bracket

Would the speaker pod help with the sound/bass or would the added cavity with the bracket help/hinder the sound?
Would the bigger BT speaker make a difference in terms of sound produced and/or quality?

Thx!
