I am admittedly a noob when it comes to speaker tech, but I love great sound. My questions for those of you in the know is the following.
Is there are significant or noticeable difference to the performance of the on wall versus on/in wall design? Does the lack of a back chamber make the on-walls a less desirable choice?

I'm trying to plan my setup and if there is no significant difference, I may go with on-wall for portability if I move.

Cheers!
