The wires of the voice coil:
are brought out onto the cone and then soldered to the tails. If that connection is damaged or poor then the speaker will cut out. Or of course they may be a fracture in the wire.
Repairing it is not easy because the area is contaminated with glue and varnish and so on. I don't know what any recommended repair procedure might be. The wire won't solder unless clean and so you are down to gently scraping, perhaps with a sharp craft knife and then seeing if the joint can be reflowed (resoldered) but I don't recommend just diving in at this point.

The external flexible tinsel wire is soldered to the internal voice coil wire where they join at the cone.
If you are lucky, the judicious application of heat from a soldering iron may renew the solder joint.

On some of their 12" speakers, perhaps just the full range ones, Wharfedale used aluminium voice coils. If that is the case with your woofers, then my suggestion won't work.
And, as Mooly says, the hair thin voice coil wire itself could be fractured just on the other side of the solder joint.

Hmmm.... thanks for your help, I can see & do understand what you are saying , I can see there is a kink in one of the voice coil wires, the same one that kicks in when moved...
Hello Mooly, Galu, thanks again for all your help. I'm hoping it's my lucky day. I gently smoothed out that kink , but then discovered it wasn't that. It is when i move that wire from left to right , so I've used some electrical tape to hold it in position. My amp is a Akai AA 8080 , just cranked it up , tried the loudness channel and turned up the bass, sounding great now. Can't thank you both enough.
It sounds like the kinked tinsel wire may have been touching the other tinsel wire. In that case bend the kinked wire away from the other one. Whatever you do, do not restrict the ability of the tinsel wires to flex with the movement of the cone.
