stupid question

[rookie]

is it bad for the reciever or the speakers to run a pair of speakers with a jumper wire in between from a single line out from the reciever?

ex: reciever FR, wire, speaker, wire, speaker

As long as you don't go below the minimum impedance that receiver can
handle, than you're good with it and cannot harm the receiver. If your
speakers are connected in parallel, than the combined impedance (which
the receiver "sees") is half of what it is for one speaker (supposing
the speakers are of the same type). If connected in series, it's
double the impedance of single speaker. (Parallel: receiver + to 1st
speaker + to 2nd speaker +, same for - ; Series: receiver + to 1st
speaker +, then from 1st speaker - to 2nd speaker + and from 2nd
speaker - to receiver -)

So check your receiver's minimum tolerable impedance and calculate
what impedance you're giving it with your speaker configuration (per
channel, of course). If combined speaker impedance is the same or
above the minimum for the receiver, you needn't be afraid that
something would go wrong.

Do you mean to run 2 (pairs) of speakers from one (pair of) output ?

It depends on speaker impedance and how the receiver was designed.

In short though, yes it can be bad. This isn't something a non-expert
should do.

I don't think it's a good idea, either. Do you want to place speakers in two
different rooms? Then you could probably get a speakers' selection switch.
My godmother has one, which she bought in Germany (she's german).

thank you MARCOPOLO for your great information. does everybody else reading this here agree?

some more details: reciever's manual says speaker impedance requirement is 8ohm to 16ohm. i would like to run (2) 3 way speakers off of the front right out and (2) 3 way speakers off the front left out. all my speakers are 8ohm.

if MARCOPOLO is right about crossing the +'s and -'s between the speakers to achieve a 16ohm load is this a bad idea or harmfull to the reciever or speakers?

thanks for your help everybody

So minimum impedance for your receiver is 8 Ohm. Than, if you want to
be able to play all 4 speakers simultaneously, the only way is to
connect them in series to achieve 16 Ohm load per channel (or, as you
say, "crossing the +'s and -'s between the speakers" ;).

Nothing harmful can be done with this. The only disadvantage of this
kind of connection is the fact, that your receiver won't be putting
out as much power as it would if two 8 Ohm speakers were connected.
You lower the power output per speaker two times: 1st by raising
impedance (lower receiver output) and 2nd by number of speakers
(lowered power from receiver is now split 4-ways istead of 2). So if
your receiver is not very strong and struggles to "move" the speakers
satisfactory when just 2 of them are connected, it will have even more
problems with 4 of them.

Of course the "disadvantege" can be totaly ignored in case your
receiver is very powerful. In fact, I guess 16 Ohm impedance can even
be superior to 8 Ohm in terms of speaker control. Good luck!
