We recently got a Samsung HT EM54C surround system and I have no experience with home theatre, surround systems, etc. I was wondering if it is possible to DYI a inside the wall mount for the rear speakers?

I know how to fish the wires, cut a box for it..but otherwise unsure. The speakers are not designed for slush mount so I don't know how to hide the edges or whatnot...or if this is even feasible.

They are very small speakers.

Thanks in advance for any advice, tips.
