well at least i had the foresight to take my KEFs out of the lounge before my son had friends over. i put the wharfedale crystal 40 from the gym there instead.
however i am not smart enough to know that not everyone understands what " too loud" and "you will damage the speakers" means.
sooo, i now have two speakers with blown tweeters. they are unpleasant sounding. they were never great but they were tolerable for the gym and occasional pulled in for duty for other things.
i am not keen to spend alot on them but would rather make them usable again then throw them out. the tweeters do not look easily accessible though. are there externally mountable replacement tweeters with built in capacitors? any other suggestions?
cheers muchly

Check them out with a multimeter set to ohms as shown in this video: If they're faulty remove them and send to Axent Audio in Auckland. I've had them repair blown speakers and found the cost reasonable. axent002.myob.net/contactus

Hi;- at least you had foresight!
Tweeters blowing can be from under powered amps going into distortion, or even powerful amps with the treble turned up... or not.
However.
You can't just check any old tweeter in there, without knowing its characteristics (you'd be connecting it to the existing crossover).
A little research shows that the Crystal 40s have a uniquely mounted tweeter.
Further research shows that the same tweeter was used in several Wharfedale speaker lines (and why wouldn't they do so?).
So, this tweeter is what you want, perhaps: It's not clear whether they have just the one, or more.
Replacement Spare Part tweeter wharfedale Fits to : Diamond 8.1 Diamond 8.2 Diamond 8.3 Diamond 8.4 Diamond 9.6 Crystal 40 [ ... ]
They want 36 euro ea.
OK, so now we know it's a Wharfedale 0326H tweeter we're looking for, how about Ebay?
The only exact ones I found were these. You'd have to either negotiate the crazed potential postage price or get them to send to a friend in the UK, get them to send on to you.
Maybe that's all possible. At a price, and only just available, but perhaps a way to restore to original.
(You could talk severely with the kids, pointing out the cost, but also - perhaps educate them on why and how turning it up can blow tweeters, and how to avoid it - and don't lose control of the party? ;-)
(Introduce them to the physics and everything about the hi-fi gear? Well, I'm single, no kids, but I've still seen irresponsible party-goers! On the other hand, teach the equipment limits as well so not again!)
But they've got curved cutouts below - perhaps though the same tweeter behind the plastic? You might have to -as I would- find out how to disassemble the speaker, get at the tweeter. After all, it was assembled. So you can see how it is mounted, & etc.
(I see also a result for a Wharfedale speakers Tweeter model 0236H but I don't know anything about that. I feel I've done enough for tonight! ;-)
Except;- why did you think they didn't sound that great before, gym, etc? Could it have been where they were placed in the room, relative to walls, & etc.
And what is the home amplifier (and the gym one?) - just curious! ;=})

The thought also occurs to me that if they didn't sound good in the gym, quite apart from necessarily correctly worked out placement in the room or not, relative to the walls, and all that;-
Is there a chance that they had also been over-driven there too, even affecting the mid bass & bass as well?
Do either of them scrape when their cones are pressed gently inward, fingers centered around dust cap?
You can probably do quite a lot of starting investigation yourself. Work out what is what. OK, what are the actual faults.
Tweeters likely blown, open circuit, so need exact replacements. But check the mid bass & bass drivers too. Maybe they're OK.
And why did they seem to sound bad before?
Could it in fact have been just down to room placement, which is a tricky enough subject in itself? Or something more?
And so on. ;=})

RdM I think the Crystal line was one of Wharfedale's lowest tier products, quite behind the Diamonds. So just inherently, not that great a speaker.

Brilliant! I didn't think to look on TM. Yeah, 8:01pm. Still it seems he has several so will likely re-list. fishheadsoup hasn't been online since the original post so let's hope it's seen in time. Seems a perfect solution.

Still room placement and wall spacing and all that could at least optimise the sound to whatever it was capable of, n'est-ce pas? Imagine them wall mounted in a gym say!  . It's an unknown as yet.

OK, he hasn't re-listed yet but likely will since he has several to sell. One can ask him to relist, perhaps.

hi, very sorry its taken so long to respond to your advice everyone. i cannot for the life of me log in on my imac and my
phone is near impossible to use with my new contacts!
ok. so i have the speakers hooked up to a yamaha rx-v440. main speakers on the floor about 20cm from back brick wall. surrounds and centre above and against wall.
i will be honest here and may have wrongly accused my son! as i had all the speakers going i may have missed the fact that the tweeters were already blown when i bought them!
anyhow the fact is i'm not sure they are worth fixing even if i can get the replacements. has anyone had a good listen to a set of these in working order? they came with the home theatre amp i bought for the lounge, a yamaha rx-v861 and i only ever wanted them as back ups.
i'll quickly try and take the front panel off (can't post pic damn) as it looks like the tweeter is attached. at least then i'll know of ot os a home job.....

No worries, great to hear back from you. I've had computer problems too!
Speaker placement seems good.
(from:)
So great, no blame, no shame.
I've been fooled too, even having listened to a pair of NAD 3-way before I accepted them off TM, albeit from a battery powered walkman or discman, I didn't realise until later that the tweeters were blown.
For $100 (or negotiate, buy one and email re two, or just accept!) you can replace the tweeters. As expected, the auction is relisted and I'd bet it still will be, so you could take your time.
But why not fix them? Better resale value too.
Cheers!
PS: I found this review:

As above, I reckon they'd be worth fixing;- to both hear them as intended and for resale value. Or just for continued use after deciding they sound good enough for where they are.
But make haste slowly with figuring out how to access the tweeter rear.
Maybe those front plastic shrouds or surrounds can be gently levered upward and off with various blades inserted into a gap? Some Philips ribbon tweeter speakers I had were like that. They were assembled, so they ought to be able to be disassembled... You just have to figure out how. And then how the tweeters are attached. Are they glued in, or clamped in, or what?
I reckon I'd do it if I were me. ;=})
Of course I mean you.
I think might as well get the best out of it. Maybe you can even improve the capacitors in the crossover. ;-)
A marvelous opportunity to restore them to original.

i managed to get the front panel off. it holds the main driver (other may be passive?) and the tweeter. the crossover is not accessible from there, the wire lead me to think is closer to the binding posts.
i will test the tweeters and make sure they are both shot and its not something else.in the meantime i put the surround speakers on top so it sounds less rubbish while watching tv. i just won't
listen to music on it!

Excellent! So if they are shot then get the replacement tweeters. Maybe the crossover is accessible through unscrewing the rear binding post panel? (I haven't looked.)
Maybe they won't sound so bad after being fixed up?
