stupid question
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 |

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. |

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. Graham |

Do you want to place speakers in two different rooms? Then you could probably get a speakers' selection switch.

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 |

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! |
