Hi all.
For reasons I'll leave out, 2 of our speakers (the monitors for the band) are in my house among other things. Being bored and knowing that the tweeter on one wasn't working, I opened it up to look. Lo and behold, the tweeter works (probably) but there's a loose wire.

The speaker is a Wharfedale Pro PT-12, the woofer is branded D-003.

It's at this point I realise that having BOTH speakers means I will just open the other one up and see where I should reconnect the wire to - but since I'm almost finished, I'll post this to remind everyone to check their wiring on half-broken gear, and do it before you suffer it for 4 months :(.

I found a loose wire inside an old Fender Bassman once. I was a kid, WTF did I know?
Well, I thought that it LOOKED like I found where the broken end went, carefully soldering the frayed wire to a point that it appeared to have broken from. Well that point was actually at the "Ground" switch that they used to have on amps before grounded plugs...and that "broken point" was the capacitor for the ground switch. I was only 14, can't remember what I DID solder the wire to, but when I plugged tha amp back into the wall socket...POW!!! No more '63 cream Tolex Bassman that I'd just spent my hard-earned $75 for...LOL!!!!!!!!
The moral here is: Beware of loose wires!

Well there's one loose wire, I've wired it to the same place as the other speaker is in.
Also, before I looked into the other speaker I was looking at the wiring on the tweeter. The way I planned to re-attach it is essentially the same as how it is wired.

FWIW the wire that came off appears to be the ground from the tweeter (I guess, as it returns to the wiring along with a cable from the woofer - common must be ground).

You are correct sir. The negative is usually common between the woofer and tweeter, (and almost universally color coded black) If the negatives are not wired directly together they're tied together in the crossover circuitry. You should also be able to distinguish which is the negative wire coming from the speaker jack and follow it through that way.

You know what would make short work of this ............. a multi-meter :)

As we've discussed elsewhere - Aren't you glad you didn't give your hard earned money to somebody else to fix it?

Keep tinkerin' brother Monkey, keep tinkerin'
