Hi all! I just got a second hand pair of wharfedales diamond 8.4 They were supposed to work perfect before I got them but today I set up the whole system and the surprise is that one of the speakers is not working. Well, actully it sounds, just the woofer, and really low and bad. I've tried plugin the bananas of the other speaker(directly the signal that the other speaker was getting) and... definitely the problem is with the speaker. Any ideas on this? Should I try opening the cap on back (where the bananas are plugged in) and sneak around? Besides, I'm testing the "healthy" speaker and now I've some doubts. Of the 3 "drivers", the mid-range driver is the only one going crazy. The woofer doesn't vibrate, I don't feel mucho movement going on with it. I've changed the setting to power up the bass and down the trebble, but the woofer still doesn't vibrate. Is this normal? Thanx! Javier
No - sounds like the speaker/ cross over is faulty - I assume there are only one set of connections on the back - on some speakers you have 4 connections for dual wiring - and you usually bridge those out Play a piece of music with some drumming in it and you should see the midrange move a lot Just to make sure there is not a problme with the Amp - swap the speakers around - so you have a left speaker and a right speaker connected physically move the left speaker over to the rightside and connect to right side cables - and the right speaker to the left side and connect to left cables Now if the problem goes over to the other side - its the speaker thats fault if it stays on the sam side - its the amp

just looked at the manual here
http://www.wharfedale.co.uk/images/range...
and they are bi-wired speakers - so make sure the bridge is in place
sounds like a cross over issue maybe the caps have gone bad -
can you take them back to the guy who sold them to you - before you start opening them all up ...
otherwise you could try opening the box....
it may be the crossover, the connections, or faulty blown up speaker drive units....
you could call wharfedale and ask how much a replacement cross over would be....
and replacement drive units - its not a make i have taken apart - but they are very simple to replace the parts - assuming the crossover does not have any settings (variable pots ) on it that need a wave machine and sound room to set up.
I have replaced speaker drive units in monitor audio, Bose, tannoy, rogers, spendor all quite successful for people. Never replaced a cross over yet.... they are normally pretty stable electronic items

Hi,
Thanks for the comments.
I've checked the bridge on the back and it's in place. If I remove the bridges they I hear nothing at all.
I've tried plugin the cables just to the LF and HF inputs (separately). In the good speaker both work.
In the faulty speaker, HF doesn't work at all and LF works really bad and low, plus only the big driver works, bad, but works a little bit(woofer?). The mid-range driver doesn't make anything and in the other speaker the mid-range is the one that really makes everything and vibrates the whole time (the woofer in the good speaker doesn't really vibrate).
I know it all sounds quite strange... but that's what I'm dealing with now.
You think opening the back cover (where the connectors are) would help??
The problem is that I bought them second hand vie eBay 3 months ago. I couldn't test them earlier because I didn't have the amp yet. I got it 2 days ago.
So, that cross over issue, would it have an "easy" solution?
You think I could try it myself?
Thanks for your help!
