Tweeter making a very slight crackling sound....causes?

[Latina33 10+ year member]

I'm not sure if it's actually making a crackling sound, or it's just playing such detail in the music that it's playing pre-recorded imperfections, but I think my driver's side tweeter might have a very slight crackle sound going on when I'm playing music.

I've put in accoustic-based tracks, though, and the crackling sound doesn't seem to be evident at all, but then I put in other rock tracks, and I swear I can hear just a little bit of that noise.

Is there something that might be causing the tweeter to crackle even the slightest bit like it is, or might this be something else? It doesn't sound blown by any means, it just seems to have a slight crackling sound.

Any ideas? Or am I just hearing things?

too much power for a low xover slope?

Yeah? Even if it's only seeming to come from the one tweeter?

The other tweeter seems fine.

try uping the xover point some.

Cool, I'll mess around with it some.

I'm running my comps active, and the tweeters are currently set at 4hKz, 18db/oct slope. I've tried them at the next setting down on my HU, which is 3.2hKz, and the tweeters don't seem quite bright enough for me. I've also tried to adjust them up to 5hKz, and there's just too much seperation between the midbass and the highs (my mid-hi setting is set at 3.2kHz, 18db/oct).

Thanks for the inputs, btw, db. //content.invisioncic.com/y282845/emoticons/fro.gif.c695f1f814b01c4ad99fe7f8cccadd29.gif

What tweets do you have? You may just need a steeper slope.

Steeper slope....so you thinkin' I should adjust the tweets from 18db/oct to 24db/oct?

yeah, I'd try that 1st.

Hmm. Cal-26's at 3.2khz/18db shouldn't be hurting...from rainbow it comes through at either 2.2 or 2.6khz...

blown

Yep. I would suspect they were run temporarily at a very low crossover or full range at volume...

which goes back to my 1st post................

Blown, really? It's not noticeable ALL the time, on every song, and when I play a lot of accoustic music, like I said, it's not really evident.

When a tweet is blown, wouldn't it be pretty obvious by the sound output....or it would just stop working?

Are you sure it's a crackling sound, or is it a hiss like all the words that have an "S" in them blend together?
