Currently, I am testing audio in the xiled rumination concentrator. So far, it sounds pretty good. There is a salvaged Sony receiver (Model STR-SL7) that I picked up from the dumpster at work. It works, but the digital display does not so I have to fuss with the menus blind. Good thing I found the manual online. It also has a big dent on the top. There is a set of Zenith home theatre speakers and subwoofer attached to it that were left behind by the previous owner of my house. The receiver requires speakers with a range of 8-16 ohms, but the speakers are only 4 ohms. I ended up wiring the speakers in a series (for a total of 8ohms) and only having the left and right channels + subwoofer, with 2 speakers facing me and 2 speakers + subwoofer behind me in the concentrator. The wiring is basically this (sorry for lame drawing...need Visio for gopher): ___________ [ SONY ] [RECEIVER ] [ ] [Left Speaker (rear)] [Left Speaker (front)] [Left POS ]->->[POS]->->4ohms->[NEG]->->->[POS]->-4ohms->->[NEG]->-> [ ] / [Left NEG ]<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-8ohms<-<-<-<-<-<-< [ ] [ ] [Right POS ]->->[POS]->->4ohms->-[NEG]->->-[POS]->-4ohms->->-[NEG]->-> [ ] [Right Speaker (rear)] [Right Speaker (front)] / [ ] / [Right NEG ]<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-8ohms<-<-<-<-<-<- [ ] [SUBWOOFER ] [ OUT ]->->->->->[Subwoofer Amp]->->->[Passive Subwoofer] [__________] ->-> <-<- is flow of power The Zenith subwoofer is passive but the receiver requires an active subwoofer. I have an old amp that I salvaged after I totaled my bike a few years ago, so I hooked that up and it seems to work perfectly. Not sure if it's bad to use that, but that's what I've got. Yeah, the setup is a bit much, but I got to learn stuff and now have nice sound and thumpin' bass from parts that would have otherwise ended up in the landfill.
