Oops, I think I may have ordered the wrong ones. Well, not "wrong" per se, but not the ones I was referring to in that link. When I looked at the URL to the link you posted (since part of the link was replaced with *****s), I saw the term RS20, which led me to these:http://www.speakerrepair.com/Merchan...duct_Code=RS20
I thought those were the ones you were recommending, and I just happened upon the others while I browsed the site.
At any rate, I called speakerrepair.com, and the guy told me that the connectors above would be fine for my needs, and since the heat shrink strain relief tubes are so cheap, I figured I could save a little money by doing a bit more work. So once I get the connectors in the mail, I'll take a look at them and the wire I have, then see what I can find at the local Radio Shacks in the way of heat shrink tubing. Maybe some nice clear ones so they don't interfere with the aesthetics of the connectors, which I think look pretty nice (not that anyone will really be looking at them).
Anyway, thanks again for your help. I'll check in once I get the ball rolling to let you know how it went. I just got started on looking into room acoustics, and I'm starting to think that I may have to tinker with the location of my subwoofer, so I'd like to have a better idea about where it will ultimately be positioned before I go cutting up my wire. As a non-hobbyist, this is turning into an awful lot more work than I originally bargained for, but hopefully when all is said and done, the time I put into researching and putting this stuff together will be worth it!
