When my speaker wires come out of the wall thru the drywall just wondering what everyone is doing? Just coming thru the drywall hanging down? Using boxes w/ plates? Etc.?
It’s popular to use binding posts mounted to wall plates (w/electrical boxes). However, that’s pretty pricey, and it makes for four times as many termination points as a straight-through connection. Besides, IMO as a former installer, the hallmark of a first-class installation is “no visible wiring,” so what’s the point if no one is going to see them anyway?
I’d simply install an electrical box and use a blank cover with a hole drilled in the center, and take the wire out directly to the speaker. Or, if your speakers are wall-mounted, you could come straight out of the wall, directly behind them, to the speaker.
Wayne's suggestions are good. Another thought though; If your speakers are away from your walls, and you're running "in-wall" speaker cable, it won't look very good. For that reason, I put in wall plates and wall connectors purchased from Parts Express.
I then used a decent pair of speaker cables that looked better than "in-wall" speaker cable, to go from the wall plate, to the speakers. Looks good, but as Wayne said, the down side is the additional number of connections. You can see a picture of my speaker connections on my web site below.
