Why not? You have to get the wires out of the wall somehow. Were you planning to just have bare wires sticking out of the wall?
I was planning on having NO wires sticking out of the wall if it's up near the ceiling. I think you're assuming that my rear speakers are wall mounted, and they aren't. So my concern is patching the wall or ceiling where the wire needs to be fished through, down to the base of the wall where I always intended to install wall plates with banana plugs if I went the wired route.
Monoprice - wall plates with banana jacks along with a few sets of banana plugs to connect to them. You'll need FOUR banana plugs for each channel if you're using a wall plate with female connectors. The other option is a wall plate that passes a cable, then you only need two plugs that will go directly into the speakers. Or I suppose none if your speaker has only clamp/spring connectors on it.
4 for each channel? So I need 8 plugs total for my two rear speakers? I don't think I'm understanding you correctly. I just assumed four jacks.
I got the wall plates for my mom's home from Monoprice. It's the only place I would go

I'll probably get the speaker wire from there too, if I don't have enough left over from when I ran wire at her place.
Her home was much easier because I had a utility room I could easily route the cable through. I don't have anything like that (no attic or anything).
