You can always turn up the center channel volume.

I think just trying an M2, then send it back if not satisfied is probably warranted at this point. Without being mounted on a wall, I'd go with an in-wall model, mounted into a piece of wood that fits the hole. Some renovation, but very minor. Can build using hinges on inside to make it easy to tilt upward.
