Can't get the back off of my Wharfedale Diamond's. Model 7.1
Basically, I've got a pair of Wharfedale loud speakers, diamond model 7.1 and the speaker inside has blown. I've looked everywhere but there are no screws present! I need to get the back off and ended up resorting to prizing the back off with a screw driver. This didn't work either. Anyone have any advice?

The voice coil of your speaker is scratching with its magenet body inside. It can't be repaired. Whatever we do will go in vein. there is no possibility other than replacing this speaker. Some people will recone it, but qulaity cannot be assured. it will sound; but with respect to the other speaker, it won't match. Coil position, resistance, number of turns per unit length ete are determining the magnetic strenth of the coil, and therby sound. Wharfedale eill have its secret, and they wont give it out, as they have gained it with tremndous reserch.
So in my opinion, it will be best for you to replace the damaged speaker with and other one of same type and number. All details will be printed on its body. Buy the original one. Do not compromise. Woofers are the heart of any sound system. Keep this in mind. OK.
Put the jumpers back in as shown. Hook your speaker leads to either top or bottom. The entire array of drivers will be active.
Make your receiver aware they are LARGE for the purposes of bass reproduction so some bass will get out to them. FYI, many AVR's will only allow Large Rear speaker selection if you also have Large Fronts. Refer to the manual(s).
With some speaker cabinets, the manufacturer will put some form of adhesive to seal the speaker to the cabinet so there's no space between them. I've often found that all it takes is to use a thin bladed flat screwdriver and insert it gently between the speaker frame and the cabinet to break the seal and free the speaker. You may need to tap the screwdriver in a bit, then twist it, but if you find you must use a lot of force, this may not be the solution for you. Please rate my answer, thanks.
The spkrs sound like they are bi-amp spkrs, meaning you have multiple terminals on the backs of each spkr, the jumpers on the spkrs should be connected as such. Now you just connect the spkrs according to the Denon spkr conection diagram. Do not use the surround back unless you have 6 or 7 pair of spkrs
On the back of the speaker are six deep holes that screws the back panel to front baffle.There are six sponge plugs normally.You have to dig these out with a long standard screwdriver or however you can get them out to expose the 6 Phillips head screws below them.Remove the 6 Phillips head screws and the whole speaker comes apart,leaving just the box.Good luck.
Is it old ? Is it making a rattling noise inside ?
Completely lost its sound as in completely stopped sounding like a woofer and has higher frequencys coming out of it or as in no sound at all coming out of it ?
I would say it's probably the crossover, perhaps a burnt resistor.
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
