Re: tweeter "drive" out on wharfedale svp - 15
Can you check the resistance of the HF driver(tweeter). If it is open it will need a new diaphragm. Most of these speakers use a lamp to act as protection for the HF driver. Sometimes these lamps fail. You will need to pull the horn out of the cabinet to check, and the rear connection panel off to get access to the crossover where the lamp is located. Get back to me here and I can talk you through fault finding the speaker.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

The tweeter has burned out and cannot be salvaged. I also own a pair of (ex) Melton 2s. In the beginning Wharfedale were good at supplying spares (see www.wharfedale.co.uk for contact info and advice). A few years ago after my cat destroyed the 12 inch unit in one, i invested in new insides, including state of the art 12 inch woofers, 4 inch mid range and 1inch tweeters with a good 3 way crossover. The cabinet is great so consider asking a techie friend to do this for you. Please don't just cut out and connect to amp speaker wires! You will get terrible sound and risk ruining both amp and speakers! Best regards Karl (firstname.lastname@example.org)
you should first try if the driver is really gone or not, maybe it's just a wiring problem, also there can be something wrong with the cross-over network. Check the tweeter with a multimeter, if you don't see something between 2-16 ohms, you need a new one (or two, you probably won't be able to find the original part, so you'll have to change both left and right channel drivers) but if you see the desired impedance on the meter, check the internal wiring, crossover solder joints, capacitors, etc. I hope this helps.
If you have never overdriven the speaker, it'll probably be a dry solder joint in the crossover. Take all the screws out the back panel, the crossover is mounted on that. Unscrew the crossover board, redo all the solder joints, finaly make sure the cheap spade terminals are connecting to the speaker properly, then put it all back together. You can check all the connections if you have a multimeter. Same happened to me.
The tweeters are probably blown, i had the same problem.
You can test this by placing the cable on the dismanteled crossover at the back of the speaker. colour blue/yellow.
No high volume please.
If the tweeter is blown it can be dismanteld with the aid of a screwdriver, horizontally.
Place it between the tweeterbowl and the ring which has the mark wharfedale on it. The tweeter comes loose. On second hand sites you can buy little speakers, like modus one or two's with the same tweeters for a good price and put them on your larger speakers.
This is not a solution, but I have the same problem. Obviously, the problem is with the tweeter not the crossover. I can't find a replacement tweeter so i am about to take it to my local stereo repair store and see if they can fix it. If you find a replacement tweeter, let me know.
