Hi all, I have a set of the old Energy Take 5 speakers as well as the Energy ES-10 10" subwoofer. I bought these as a package back in 1998 but I've yet to replace them because they still sound good and all I currently have is a 10' x 12' living room to work with, so the speakers' size is a nice fit for a smaller room. The receiver I'm using is also pretty old (Kenwood VR-407). Anyway, my question is as follows: on the back of the ES-10 subwoofer, there are inputs for two type of connections: high level terminals and a low level RCA jack. I assume that the high level output produces better sound, but I've never actually had the subwoofer connected to my receiver using the high level outputs. In the past, I've always had it connected to the receiver using the single subwoofer port on the back of the receiver and to the low level RCA jack on the subwoofer. I don't have the subwoofer in front of me right now, but IIRC, the high level terminals use speaker wire, as opposed to the RCA jack that the low level output uses. With my setup, should I be using the high level terminals (for presumably better sound), and if so, what do I connect the other end of speaker wire to on my receiver? Thank you very much for the help.
