I've had my Cadence X sub for four years know and it has always been hooked up through high level input, because I thought that High level meant better, boy was I wrong. I have a cheap onkyo sub using a coaxial cable and today I was looking for a subwoofer cable and somehow came across the fact that it was possible to use my sub out and hook up to my cadence xsub. I thought since it had red and white that I couldn't hook up a subwoofer cord to my subwoofer. I know this sounds crazy to you guys who know this, but I didn't. After doing research I found that the speaker wired connection to my sub was using my AVR's power instead of its own.
I decided hey lets try it and see if it makes a difference, I took the subwoofer cord from my onkyo and hooked it up to one of the rca inputs. OMG, OMG, OMG, This made a world of difference, listening to this sub know makes my house rattle and music sounds like im in the club. I cannot believe for four years I never knew the true power of this sub. I was so excited by the sound and bass, I almost literally shed a tear realizing that for years I had neglected myself of a true surround sound experience, and that parties I had thrown could have shooken people to the floors. I searched the internet before I decided to change the connection and no info was truely conclusive as to which was best although most said use rca. Before the low level hookup, I was using two subs to get a good sound, know I only need one and it sounds like 3 subs. This setup is only using a coaxial cable going into one rca input. I don't know what to expect when I get a real subwoofer cable, and a y adapter, I may cry in joy at the beautiful sound. This is for those out there who wonder which is the better hookup. Low level is unbeatable, and I don't know why some people refute this by saying that sometimes they can't get bass during music, to them I say something is wrong with your system.
