I recently moved into a townhome. The living room appears to be wired for surround sound. Where the satellite speakers would go, there are blank wall plates.
Behind two of the wall plates are boxes/brackets as shown below (you can see the gray speaker wire running up behind it).
What is this type of bracket intended for? It looks like something is meant to fit inside the semi-circular openings, or perhaps they are supposed to bent away? I haven't been able to find anything similar online.
In general I think the pros prefer the wall plates. It gives it a cleaner look especially when nothing is attached (no components are installed yet).
I know some audio/video-phile types actually prefer "big hole" method as it cuts down on the number of connections. Imagine 1 cable (2 connections, 1 at the cable box and 1 at the TV) compared to 2 cables (4 connections, 1 at the cable box and 1 at the wall, then on the other end of the wall and at the TV). If you do modular plates behind the TV too you are now talking about 3 cables. Of course the overall length of the run will be about the same.
I too am torn about this, I think if I am just doing it for me I would go with the big hole approach. If I was planning on reselling the house and I want the room to reallly look "finished" without my AV equipment installed I would do the wall plates.
EDIT - It looks like you already found www.monoprice.com so you have the best source for these things figured out :)

That is an Erico MP1S bracket. Used for low voltage wiring, the tabs can be bent back and 3/4 conduit attached to it.
