Blown Speaker??


Lol, leave it to the guy who posted another thread about being able to smell his speakers :-)

Okay, so yesterday at the end of my listening session I started to hear a little crunchiness in my right uni q mid / tweet driver. Thought to myself "huh, wonder if that was the recording or my speaker". Anyways I shut er off and didn't turnitback on till this morning. Immediately, and at low volumes I heard nasty nasty crunchiness/ distortion and thought "yep, blown speaker". Pushed in on the driver to see if I could feel crunch going on but nothin, smooth and glass. Pulled driver out of speaker (quite unfun by the way on a pair of qx5's) and pushed / pulled driver in and out to see if there was any crunch there; nope, nothin. Put driver back in speaker and now I don't have the crunchy distorted sound any more.

I don't think I "fixed" anything by pushing / pulling on the speaker, I think the crunchiness worked itself out, possibly as the voice coil warmed / woke up? I would be more suprised if I didn't hear the crunchy sound again than if I did, especially after a resting period for the speaker.

Have any of you experienced this same scenario? I've already sent kef an e-mail asking about pricing and availability on this driver, so we'll see how much a uni q costs.

By the way, I sniffed the innards while I had my speaker dissected and still couldn't detect where that dang smell was coming from. I'm still thinking it was hot voicecoils / glue warming up? or hot crossovers. Who knows, but I haven't really smelled that smell since the first time a couple of weeks ago when I started that other thread about smelling your speakers when rocking out.

By the way, I partly blame those dang pangea powercords as the addition of them brought out so much more, and deeper, bass. Not complaing, it's just now, with other changes that I've been doing to my set-up, my system really has the grunt to start damaging speakers and not in the "too little power, too much distortion sense", more the "lots of power, lots of dynamics" sense.

Schipo, it's not yhe Pangea cords, I'm thinking that it might be do to the amount of bass that I'm getting now from the addition of the pangea power cords. I know that sounds stupid, but seriously, my set-up has quite a bit more bass as a result of the power cords, in addition to a lightspeed attenuator that I recently got. And like I said, I'm not complaining one bit, because in comparison to cheap factory supplied power cords and my old classe ssp-25 preamp, my setup went from sounding flat and lifeless to pretty dynamic with quite a bit of punch in the bass regions. If you've ever done upgrades to your system that yield those results you might understand what I'm thinking.
So strange, didn't hear the noise coming from the speaker at all today. Is it possible that there was some sort of debris in the voicecoil or something?
I second Csontos, It has happened to me before. A piece of debris get trapped between free space of voice coil. Manually moving voice coil often removes this.
