Not quite DIY but here goes.I have found an ancient pair of Wharfedale bookshelf speakers in the depths of the garage and would like to wire them up to my separates system to use in another room.There are the remains of two wires on the terminals,one is grey the other is grey with a black trace.Can anyone tell me which is positive and negative please.

If you really must know, take an AA battery, and connect across the wires, while observing the speaker cone. Compare all your speakers, so that they move the same way. This doesn't matter across pairs of speakers, as long as they are wired the same. It also almost certainly doesn't matter between rooms. |

Lets say that as long as the tow speakers are wired up the same way, it doesn't matter. |

I don't think that question has a definitive answer. As long as you connect both speakers the same way, and they are in different rooms to your existing speakers, then all should be well.

'Flick' a low voltage DC source across them. A single cell battery - AA, etc - is ideal. Observe the direction the bass unit moves.

Que? if one is wired one way, and the other the other way they will be 180 deg out of phase with each other, and the result will be a loss of low frequencies (very technical explaination skipped, bu I can post it if you want), but both wired backwards makes no odds on most speakers. If they are using a fancy crossover it *might* make a *slight* difference, but since most book shelf speakers use a straight parallel the tweater with a capacitor to roll off the low frequencies thats unlikely. Given they have been sat in a garage id be more worried about damage to the cones and coils producing crappy sounds. Dave |

If you want to be really sure, connect them and put the two speakers close together and play some bass through them. Then reverse the leads. The setup that is loudest is correct. |
