Hi all,
Yesterday I mistaken started a listening session by playing a track at 11 o'clock on volume dial. I turned it down PDQ but fear it could have caused damage.
I've listened since and all appears well if maybe a little dull but the treble units are still playing and my assumption (right or wrong) was that they wouldn't be if they were blown/damaged.
FYI, the reason for the volume being at 11 o'clock is that I connect a Yamaha surround sound system to the Exposure's for movie duty and had been watching one shortly before.
Any advice would be greatly appreciated.
Many thanks
Paul.

When you say that you've listened since, do you mean immediately following the incident? If you didn't see or smell any magic smoke the likelihood is that your speakers will be fine.

I'd be surprised if you did any damage to be honest. I suspect we've all had the odd incident like that. Just looked up the spec of your speakers and they're meant to be good for 300 watts. I don't expect your power amp was pushing that out, but equally, it isn't a weedy thing that would have been clipping & distorting like hell at the sort of volume it must have been at.

Thanks for your thoughts, I did indeed listened to them straight away and there wasn't any smoke or smells, I also had a look at all of the drivers and they seem fine. It was such a redicuous thing to do, I'm usually so careful.
i was just convinced that throwing that level of volume suddenly might have done something untoward.

Possible but unlikely I'd say.
I have done similar before, not sure if 11 o'clock but it were VERY LOUD

If the tweeters are still working they will be fine.

If the tweeters are still working they will be fine. Usually but not always. I have known tweeters to be damaged so that part of the voice coil is shorted but they still work... albeit with a new impedance of 1.8 Ohms! If all sounds fine now after ears have recovered from the SPL shock then probably it's fine....

Yes, fair enough, though I would be surprised if a very short burst did this. Either way it seems that it would be a good idea to check the impedance of each unit with a multimeter. If they measure similarly then they are probably fine.

11 O'clock is usually not loud on any amp I've owned, Am I misunderstanding? Did you actually mean just below max?

Did you actually mean just below max? 11 o'clock is just before half way around the clock on my amp and as the speakers are +90db that is rather loud, but I guess on reality around 20-30 watts. On the suggestion of checking the impedance, how would I do that as you can easily get into the cabinets?

I seriously doubt that would do damage. I listened well past 11 o clock (closer to 1 o clock) with exposure amps and Snell Js (94db) on a daily basis. Probably closer to 1 o clock and that was wtth a Dual IV

Really? I rarely get beyond 9 o'clock with mine before it's a bit too loud for me... Smallish room I guess.

I sat about 14 feet back from the speakers which probably makes a fair difference, although I do listen very loud to the likes of Yello. I doubt I ever listened lower than 11 O'clock with any music though. I'd be amazed if you'd damaged anything: I never did...not even my ears!

I think you're ok. The tweeters are usually the first to go because of the vast amounts of clipping distortion which equates to far more high frequency power than they're used to. My son did that once, by sitting on the remote (setting the volume at max) and then playing a metal track to his friends. My Usher's tweeters were instantly fried, which was a costly replacement. He said it sounded like the end of the world.

Knowing your speakers Martin, I'm not at all surprised it was a costly experience, I would have been so unhappy had I damaged them but I think I've got away with it, phew!!

You make me think where is 11 o'clock and anything else on the Pass.
Goes from Zero to x on the front display. I rarely listen much past 60. Will look to see the highest number

It's not really possible to equate power directly to volume control position of course... stating the bloody obvious I know but I've been amazed (shocked!) as to how many people think things like "it's a 100W amp so at 5 it will be giving 50W" etc!
