I would have thought it would depend on how they are being used.

To some extent, yes.
The point I'm making is that if you have passive speakers with an amp rated at two or three times their power handling, if you turn it up on full, it's quite possible to pop the speakers.
However, I'd think that would be far less likely to happen if you turned up some actives onto full (not that my friend was running them anywhere near full volume).
If they're seven months old and he bought them new, then it's time to take them back to where he bought them - if they're not covered by an explicit warranty then they should be covered to some extent under the consumer goods act (e.g. he's entitled to repair/refund because they're not fit purpose - unfortunately the burden of proof falls on the consumer after 6 months, so 7 is an unlucky number).
In theory most of the good active speakers (and I thought I could include JBL in this range) have active limiters built in to prevent this kind of thing happening through driving the speakers too hard. However, they can't prevent something upstream of the speaker amp from clipping the signal which can quite quickly damage the voice coil or the cones (as you're effectively driving the speaker with a DC voltage for at least part of the time) - check your levels from your CD decks, mixers, EQ, etc to make sure you're not over-driving any component of your rig?

Yes...they're going back to JBL today
My friend has already spoken to trading standards, the retailer he got them from and his credit card company...so he know exactly where he stands.
He's been told the buck stops with the retailer he purchased them from.
He just has to wait to hear from JBL now. They way they respond will determine his next course of action.
Ah, the old "my friend" story. ;) :D
When did you switch to JBL's then Rob? Oh, yes just re-read, 7 months wasnt it :D :D :D
Were the Mackies getting too hot for ya? :sofa:
Justin...you surprise me.
You should know me better than that...if it WAS me, I'd say so. It really WAS my friend! I was doing a wedding on Saturday, and had no problems whatsoever.
I've never had actives. I still use my passive Mackie C300z passives, which I'm very happy with.
:D :D :D
It's possible to have a mixer which gives a higher output level without clipping than the active cab is designed for . It's also possible to redline the mixer, which is also bad news. Many active users believe that they can't damage things because they're perfectly matched, but as with anything, it can. Sorry to hear it Rob.
Spot on, the responsibility always lies with the seller within the warranty period - but with specialist equipment (and I'm sure DJ gear would be classed as specialist) it's considered reasonable to consult with the manufacturer before responding.
Something you might want to know though - if the equipment needs to be sent away to be repaired or replaced, then in the interim if the buyer is going to be inconvenienced (financially or otherwise) then the seller is responsible for providing alternative equipment for the duration (or pay for alternative equipment) if this can be considered a reasonable request.
Having said that though, this is a difficult one to enforce as these laws only apply to consumer goods, and if you buy equipment for business use (e.g. as a DJ) then it's considered a business to business transaction (i.e. not covered by consumer law...) How the transaction is viewed is normally governed by how you bought the kit. E.g. if you bought it on a personal credit card, then you bought it as an individual, not a business, but if you bought it on account then it'd be hard to argue that they're for "personal use". I know a lot of the shops round here would lend me their hire stock to cover me if gear I bought from them packed up, purely as a good will gesture, but if I pushed it they'd probably start pointing out that I don't have a lot of rights as a business (it's all give and take). If they're playing nicely now, then I wouldn't push your luck ;)
