Blown Woofer in Marble 9.0?

ribit · « **on:** 29 Aug 2003, 09:07 pm »

Someone left the volume way up after they turned off the system. When I turned the system back on, I heard a pop from the left speaker.

Now the woofer does not work, however, the tweeter does work and the right speaker sounds fine.

Before I buy another Scan-Speak woofer, could the problem be anything else? I did all the usual testing by changing right to left, cables, etc. All that works is the tweeter.

Any suggestions before I buy the woofer?

Thanks,

Randall

Sounds like a blown woofer to me. You may want to post on Madisound, you may find a used single woofer for cheaper than the cost of a new one. Just a suggestion....

It also sounds like a blown woofer to me. Madisound has a trade in program. If you send them the blown one, they will ship you a new one at half price.

I would replace both woofers. Just replacing one might result in audible tonal shift as one woofer is more run-in than the other. Of course, your ears may adjust to this but if they were my speakers, it would just bug me no end

Replace both.. right. Actually, I swap the woofers between my l/r speakers periodically to make sure that one side isn't more played in than the other. On some records, there is extra bass stage left - so it is important to compensate.

You should switch over your l/r interconnects pretty often to avoid the same irregular burn-in problem.

Furthermore - I want you to contemplate the tonal shifts you will be exposing yourself to by having well played in tweeters paired with stiff new unbrokenin woofers.... the list goes on and on. Just buy new speakers alltogether.

This is serious stuff - don't screw around trying to save $220 by declining to replace a perfectly working revelator driver.... you are likely to be bugged no end having one side more broken in than the other!

If this doesn't bug you - you have bad ears, that's all there is to it!

What you say about replacing both woofers makes sense. I just would have never thought about the tonal shift. Would this tonal shift be a permanent thing, or would the new woofer, in time, start to sound like the broken in woofer?
Do most of you agree with replacing both woofers? Thanks for the replies.

I don't agree, just get a new one, after break in it will sound like the old one.

I hope your joking

Thanks for the benefit of the doubt... I think.

Just replace the blown one - on weekends my sarcasm gets the best of me.

Well, 2 things should happen - the new woofer will of course break-in eventually and your ears should adjust to any differences over time. But the other woofer will always be more run-in than the other and initially there might be an audible difference. Can you live with this? It really depends on how fussy you are

The Norh is a revealing 2-way design (I own Mini-9.0s) and the mid/bass driver covers the crucial midrange/voice region. The ear is certainly more sensitive to the mids, thus my concern. If you just had to replace a dedicated bass driver in a multiple driver design, I wouldn't be too worried.

Why don't you just replace the damaged driver first. Listen and if you do hear a skewed balance, change the other driver. However you may consider getting both woofers matched to ensure tight tolerances.

Let's have a poll!!

I vote for just replacing the blown woofer. They were never closely matched anyway.

I listen to music standing on my head a few days a week, so that my ears don't wear unevenly.

But how do the NASCAR drivers compensate for turning left only?

send them to me...i'll get wit ya....

sorry fer the mis-hap...

me vote is, as always to go wiff the cheaper way....replace 1....then if it's that bad after break in...THEN send them to me...

Peace, Pogue

I think you should just replace everything. And I mean EVERYTHING. Take your wife and children, and leave your house. It is cursed.

It is called "The Black Marble Thai Curse". Barnes probably never mentioned it to you, but at the old thai villages, where they make the marble drums (during an old, scary ritual, at night!), the old witches of the village, curse the drums (only the black ones). The curse makes the marble drum slowly consume the small woofers, until they stop functioning. The old witches hope that after the speaker will stop working (again and again), the horrified owner will send the drum back to thailand, where the marble will be able to become one again, with its holy land.

In fact, this is the reason why M.Barnes started the use of synthetic marble, and the reason natural marble is soon to be discontinued. At first Michael thought his R&D team would be able to to create a counter spell, but they quickly gave it up, after receiving several life threats.

He couldn't discontinue the black marble at once, since it would have caused panic. He is slowly asking for all his customers to bring back the black marble drums, in exchange for a refund, or a synthetic piece. This is also the reason why nOrh is interested to go back to wood. Scary shit!.

The rumor say that a few of the black marble drum owners, decided to reject Michael's kind offer to give back the drums, in return for a refund, and decided to go to thailand themselves, for a full scale witch hunt. They were found brutally murdered, several days after they arrived to thailand. As a small compensation, their grieving wives got the first shipment of the Le Amp II, and thai marble gravestones for the tomb (White, so no problem there).

Great story!! Did you have to argue long with them to let you have a pencil to write it down? Or did you scratch it into the wall padding with your fingernails?

Actually I thought it was a great story and so over the top that no one could take it seriously.

Maybe we should lighten up on Jonsey and start giving him the benifit of the doubt.

There is some doubt it would be of benefit... But I'll be happy to.
