@bshaw Yes the models are different but the example is applicable. Both models are dynamic driver / enclosure design.
The M2 is quite a nice choice as smallish two - way designs have come quite a long way.
My current ' stand mount ' mains are a two way design with rear ports which are placed near the ' front ' wall and perform in exemplary manner for imaging.
The example that I cited goes to demonstrate that a speaker - enclosure can be placed nearly against a wall and function well.
The 12' x 12' room ' constraint ' seems to be the immediate concern given:
" my question i guess is that can this same thing happen in a smaller room, say 12x12 or is one just limited to say center imaging due to room size ? ".
The lower the ceiling the greater a smaller space would be affected but a symmetric room is more predictable acoustically. Also note that a ' small room ' - acoustically - could be as much as 700 sqft as an example.
In general terms damping the room at one end and diffused at the opposite can work well. As with almost any rooms frequencies below 200 Hz will remain as difficult to treat in an easy way.
None of these ' circumstance ' preclude good imaging though.
Large playback systems like the examples used in the videos listed can deliver exceptionally high SPL levels in a large room. A different goal.
