The magic smoke escaped

Dr Zoidberg · 25-11-2005, 09:12

On the way to work this morning I was listening to a very bass heavy album at very high volumes.

I'd nearly arrived when I suddenly lost all bass. I turned off the stereo and when I got there I opened the boot to a burning smell.

Drifting out of the port on the subwoofer was the magic smoke that makes it work.

Time to go shopping tomorrow I think

Never toasted a sub before!

A fellow believer

Sorry to hear of its demise though

**robmawer** · 25-11-2005, 09:32

Take it repair would likely be more pricey than a new one?

It's a 10" JBL sub in a proper JBL ported box.

I should just be able to drop in a new speaker so it shouldn't cost too much.

Yup , whenever anything electrical dies there is always a little puff of smoke that escapes. This is the magic smoke that makes it work , because once thats escaped it's no good any more

depends if you can buy the speaker itself cheaper than the whole sub (i.e. the enclosure).

Might be pushed for luck though

Copper "wiring" and the like is actually tiny tiny pipes, through which magic smoke is passed to make lights flash and noises occur. As Dr Z says, when the system breaks, this smoke is released, hence it stops working.

And there ends today's physics lesson.

There must be an underlying cause for the sub failure. Before spending money on a new speaker I would check everything over as it may happen again. The most likely cause is the amp clipping and not sending a clean signal to the speaker. The remedy for this is obvious, you need an amp that has a higher rating.

Nope , 800W amp driving a less powerful sub flat out on some very bass heavy tracks for 40 minutes.

speakers are non-servicable. When the voice coil goes, you're effectively buggered..get the credit card out!!

You could replace the driver but make sure you get a like for like replacement as the box is designed taking the characteristics of the speaker into account. The wrong driver may sound poo.

Just out of interest, what was the album you were listening to?

Not sure whether i'm asking 'cos I want to buy it, or avoid it

Sounds like someone needs a JL 10w6

I meant 10w7.

http://www.caraudiodirect.co.uk/prod...60ea0e24ea9403

800w (assume thats RMS?

) would certainately kill a JBL given some stick.

Savage Garden are OK anyway - Better than most R&B/rap rubbish out there.

I thought the magic smoke came from the magic cigarette that the monkey was smoking that makes the noise in your sub, works the automatic choke, and the magic windows.
