I know of no other practical passive system other than the Hafler. The
rear
speakers are wired "ground-to-ground" with the "hot" sides going to the
"hot"
amplifier outputs.

Or to put it another way, the rear speakers are wired in parallel with the
front
speakers, then the ground wires are lifted from the amp and tied together.
Electrically, both methods are exactly the same thing.

When I was in college 35 years ago, I used this system with my KLH Model
11 FM
portable, and it worked fine.

Right, I belive this is the way I have my system wired now. BUT, according
to this website I was looking at, there is a difference between surround and
four channel surround. The way I have it wired now, I have the red wires
coming off of the red terminals of my front speakers, and the black wires
coming off the rear speakers tied together. Now, is this giving me a single
rear channel coming out of both speakers, or is this giving me two discrete
rear channels? According to the diagram I am looking at, in order for me to
get "four channel" surround, I would need to bridge the black terminals at
my amp and then run another wire from that bridge to a 8ohm 10 watt resistor
and then to either one of my rear channel speakers(in addition to my current
configuration). This would supposidly give me 75% seperation in the rear
channels so left rear information would be more "left" sounding and right
rear information would be more "right" sounding. Make sense? I haven't tried
this yet but does this make sense to you? Here is the link that I've been
using.
