I was going to purchase a used pair of two-way speakers yesterday, but when I listened to them, both tweeters were dead. These particular models have just a single pair of connectors (not biwireable).
What could cause both tweeters to be completely dead with not an iota of sound coming out?
Could these have been fried somehow, or could something in the crossovers have been damaged? Short of taking them to a tech, is there any way to know?
Thanks.

Follow Ups:
I got this information this afternoon from the seller, who took the speakers to an audio shop.
It'll cost $100 for their replacement, which brings me to this questions: Does changing them out alter the sound at all?
Thanks.

Unless they are OEM Duplicates.....part# and all, the answer is YES....something will change. Maybe better....maybe not.
Too much is never enough
Both tweeters dead points to a small amp having been driven into clipping.
In a domestic setting I have never come another cause of tweeter death.
... a four year old with a screwdriver? ;)
Yeah. Wasn't impressed...

Hey, I love children. But I find just one never quite fills me up...
(oh, now that was bad...)
I have two incredible kids 3 and 4. I don't expect everyone to like kids - especially my lively ones. But if my kids don't crack you up at least ONCE in an evening, then your sense of humor is just plain dead.
Today my son requested the "boom boom clap" song. I had no idea what it was, so I went through songs I recently played for him (he's into ROCK now...) It turned out he wanted to hear Queen's "We Will Rock You"
Boom Boom. Clap. Boom Boom. Clap. Boom Boom Clap.
When I finally figured it out I laughed my proverbial @$$ off...

My neighbor, a complete gear-head motorcycle racer (champion, at that) brought his 6 yr old over one day while we talked. The young'un turned around and SHHHH'd us. I had some classical on, at the time, and would wager the child had NEVER heard anything even remotely like it....

Ha ha!! That's awesome!

unlikely but a stupid possibility but I once had a set of speakers with dead mid-ranges that had been sent to Stereophile for review. Both mids were dead because the factory had wired both leads, postive and ground, to ground on the crossover.
I would also check to see if the tweeter in question is repairable or still available. Buying a speaker only to put a "close enough" tweeter may or may not be good enough. In addition to different response, tweeters typically have different resonant frequencies, impedance bump magnitude and "shape", and impedance rise. Any impedance correction networks or equalization networks will not work properly with a different unit, even if the nominal impedance is the same.
"Fits in the hole" is not good.
Something to keep in mind...

Understood.
I was sort of afraid of that.
Thanks.

My understanding is you can't just "drop in" a replacement tweeter for the Spica speakers. So even if I were able to get a matching item number replacement, it won't be the same as the ones in the speakers now.
So what I'll end up with is something very similar to a Spica, but not really.
Please, someone correct me if I'm mistaken.
Thanks.

Funny that searching "Spica" @ Madisound turns up zip (found it on a WWW search).
I did give them a call. It turns out I just might be able to get my old tweeter fixed, without actually replacing it.
Potentially great news.
Thanks for going through the trouble of looking the information up for me.
Cheers.

perhaps I'm recalling outdated info.
Worth checking out as the tweeters were well received in online user's reviews a number of years ago.
I was off-line/away from home, off and on for quite some time, until mid july 2011 and I think I read this (the "back in stock" thing) after I got back.
Reviews were that they were as good, or better as far as I recall with zero crossover changes.
This was for the 50, so if you have the 60 or the Angeles (sp?) I'm not certain if it will work.
Very fragile Audax with no replacement diaphragms available.
Tweeters are relatively easy to fry but it is more difficult (though not impossible) to damage a crossover.
If you have an inexpensive multimeter and the seller will let you remove the tweeters, you can check to see if you're getting AC signal through to the tweeter terminals. That increases the odds (though doesn't guarantee) that the crossovers are OK.
Depending on how much the seller is willing to take, the speaker model involved, and the cost of OEM replacement tweeters, it could be a reasonable gamble to pick them up.
Just remember you have lots of variables and no guarantees if you don't get a complete checkout from a qualified tech. Your call.
Thanks for the info.
They're a discontinued speaker model and, from what I understand, impossible to get OEM for. And also, from my understanding, replacing the speakers in this line with something other than OEM will change their sound.
At leat that's how I understood it.
I've got a pair at home with one of it's tweeters making staticky/crackling sound at certain frequencies. They've never been driven hard or anything else.
And, to be honest, I've no idea why it's even making this sound. Is it the actual tweeter making this noise, or something else, like the crossover?
Anyway, I found it totally weird that both tweeters were completely dead on the pair yesterday. In all of my years in audio, I've never dealt with this particular issue with regards to speakers. Some other stuff, but not totally dead.
I offered the seller a quarter of the asking price, thinking I might somehow be able to bring them back to life or have a tech do that at a reasonable price, but the offer was refused. The seller, instead, is looking to get them repaired (or at least look into it) and sell at the original negotiated price, which is a-okay with me since I went there with the original negotiated price in pocket.
