Learning myself a little about speakers. 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):

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.
