OH MY GOSH... second set of Seas Tweets blown...

I think people should hide their remotes and volume controls from you!

By the way, I have a CD-9887 and I have been setting it with the volume on 20 because I heard it clips past that, what volume should I have the HU on when setting it? Because I assume I still need to leave some headroom and not put it on max volume..

When I messed with tones on my 9883 it audibly distorted at 30 out of 35, but sounded clean to my ears using tones up to 29. I set everything at 27 out of 35 on the theory that if it distorted audibly at 30 the clipping probably started slightly before that. It gets everything as loud as I need it. Many people use specific test tone attentuation levels to get their desired overlap.

In my opinion 20 is WAAAAY too low unless you're absolutely sure you will never want it higher than that. I think youre HU has more left in it before it gives out. But keep in mind I'm sending a little more than RMS to my front components and they're sensitive speakers, and my sub is overpowered by 20% so this works for me and things get as loud as I need them to a t 24-25 with a few clicks left on the volume dial.

I go to 25 on my 9887

Make sure your speaks aren't connected when setting gains. Whoever said you burped your tweets was right and that's why they don't work anymore.

These tweeters are really nice once you get they set up properly //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

You did probably one of the two most abusive things you can do to a speaker. It's not the first time I or others on here have heard of this happening. Next time leave them unhooked or use resistors. Sending a flat, amplified, max volume test tone to your speakers for more than a second or two will fry them in short order.

When did the OP say he had anything at max volume? (At least regarding this second set).

Worst case, he may of hit their peak levels for a second or two. Shouldn't damage a quality product.

The only thing I can figure is his amp was clipping or otherwise sending something the tweets didn't like. Or possibly a defective product.

OP, did both tweets die simultaneously? Disconnect them and throw another set of speakers on those amp outputs. Just for giggles..

Did you hot glue them first? I would suggest doing that before you hook them up. That little metal tab with that one strand of wire is exposed and delicate as hell.

Try that if you haven't.

HE fried them, plain and simple. Speakers simply are not designed for that.

Bupring tweeters, now that's a first. Maybe you sould have someone that knows what they are doing to set the gains for your tweeters and adjust your crossover points and slopes, that way nothing will go wrong.

Stop using the "DMM method" and stop adding gain to tweeters. Everyone, right now....I command you...JUST STOP!!!!!!

 

[eharri3 10+ year member]

The DMM method has consistently given me a very clean high volume sound and a linnear rise in volume for all my stuff. O-scope is best but most people won't bother. By ear is great if you know what to listen for but most people don't and fail miserably at this method using dynamic music.

A DMM is cheap, useful for other purposes, and gives a good solid starting point for educated adjustments. I've been to a bunch of different shops that do it by ear, when I re-work with the DMM the results are always more satisfcatory to me.

People quibble too much about gain-setting technique sometimes. The more important thing is are we being logical about it and using some sort of sensible technique and method or are we just cranking till its loud enough and then throwing in boosts at the amp and head unit to make it 'better'.

Here's a thought, try LOWERING the gain on all the other drivers if your tweeters aren't loud enough for you. Or, buy more power....it's cheap! Then use your DMM to match output levels, not to set your gains...it's simply wrong.

Guys, I didn't really BURP the tweeters lol that was NOT my intentions, the gain knob was just super sensitive and I budged it..

You caused mechanical damage to the first set, thermal damage to this new set.

Sending a flat, amplified, max volume test tone to your speakers for more than a second or two will fry them in short order. Other people here have done it. I almost did it with my last set of components when I didn't really know what I was doing and I read on some retard's tutorial on the net that it's fine to just play flat 0db tones at max volume and listen for the audible tone change to set gains. Luckily I stopped right when they started to stink and they cooled off then played fine for 3 years before I upgraded.

If you're getting warranty replacements you are the kind of customer I would hate.

x2

But you don't really need resistors.

9887 clipping at vol 20/35???? wtf..

buy more, blow more. it's good for the economy.
