Default Newbie Question ... hooking up two speakers to one ouput?

"Harry Muscle" writes:
I'm really new to everything to do with speakers, but I just have one quick
question. I have a 6.1 speaker setup. However, I would like to duplicate
the front center channel in another room using the rear center speaker. The
front center speaker is rated at 20W, while the rear center is rated at 8W.
The front center ouput is matched to the speaker, so it's rated at 20W. If
I were to connected the rear center speaker (8W) along with the front center
speaker (20W) to the front center output (20W), would I blow the rear center
speaker?


That depends entirely on what you do with the volume control.

My bigger concern is whether that center channel you're planning on
hanging two speakers off of can handle the impdance of those two
speakers in parallel.

Look at the impedances from the specs of the center and rear center
speaker from your speaker manuals. multiply these two numbers
together and divide by the sum of these two numbers.
e.g. let's say they're both 6ohms, then 6*6/(6+6)=3. The result
here is the equivalent impedance of those two speakers connected in
parallel.

Now ompare that number to minimum impedance rating of the center
channel from your receiver's specifications. If the equivalent
impedance number you got above is smaller than what your receiver
specs say, don't do it. You'll drive that channel into thermal
overload at best.

To give you a recommendation of a better approach, I need to know more
what you intend to watch and listen in the other room. The best
solution involves a second amplifier, of course. Or maybe a low cost
all-in-one stereo system or boombox with detachable speakers that has
a line input that can be fed by our main system's line output...or
something like that.

Best Regards,
