So I have just recently moved into a house with 2 wall-mounted speakers. I have no idea how to connect to them, but there is this port that is in the same room with them. Can anyone tell me how to use these two ports or if they even are for the speakers?

They're probably phone lines.

There's an empty hole next to it with a visible red wire. Could that be it?

(not original poster) I've always known phone lines as having four connections, while these seem to have six. Are phone lines perhaps different in the US from Europe?

Possibly, but I would personally expect there to be some sort of port connected to the wire. Do you know who you bought the house from, or is there some kind of person that manages houses or whatever to ask this to?

not that i know of, tough there are different kinds of phone line. you have RJ10 that's 4 connections, and RJ12 that's 6. i'm sure there are others too. i'm from europe aswell (hup, holland hup) but we always had the 4 connection kind too.

 

EDIT: on second look at OP's pic, it seems like it is RJ10 too, tough with only the 4 inner connections populated, but i could be mistaken.

Maybe it's for an intercom or something?

Looks like  Rj-12 cause it have 6 "pins". Or Rj-11.

Probably for a  phones with several lines.

Sometimes these connectors are used in audio for a remote, but these are probably phone lines. 

[EDIT]
further thought that the gauge would be too small to pass audio and unnecessary complex. Those are probably extension numbers too.

Just because there are 6 pins in the port doesn't mean they are all connected. I've seen it before where you pull off the cover and only two or four wires are there. I'd also wager that the written numbers on the label are the last four digits of the phone numbers which used to be linked there. 

 

Any pics of the speakers themselves? If this is an old house they may have been for a doorbell intercom or a built in radio system. Any chance you could pull the speakers out of the wall and see what wires are connected to them?

I once received an RJ45 phone line. It came with a router that was sent by an ISP. (quite an annoying move, as it obviously didn't fit in my wall socket) I'm guessing these kinds of lines might be for enterprise use with multiple/high capacity telephone systems.

That kind of depends on the speakers. Most home speakers could easily be used on phone lines. I'd say they're fine for anything <75 watts. However, there are too many wires present for the number of speakers, and I've never seen anyone use phone lines for speakers.

More like fine for <15W. Its around the size used in laptop speakers.

Right but that doesn't mean you can't use it for more. The current on my 4 ohm 65 watt speakers never exceeds 5 amps or so, which would work with a phone line.

5 amps would be pretty nominal. Just because you can doesn't mean you should. Its 24 Gauge, probably only rated for about 2 amps.

Yes, but of course, I don't know what kind of guy has installed this. The rating of the wire may not have been any of his concerns.

Edit: again, I don't think it is used for the speakers though, I;ve never seen phone line sockets/lines being used for speakers
