So a few months back I bought the least expensive Sony-branded HTIB, and it's a great little system. For the size of my living room it sounds awesome. My only problem, and thus the point of this thread, is the length of the speaker cables. They're JUST long enough to reach the back of the room, which, for now, is no problem. However, I'm wondering if there's such a thing as speaker wire couplers so that I could extend the length of the cables.
