Hello,

I just got my brand new Kef iq90s, shipped from Kef direct. The tweeter on one of them is not working. I have a single wire setup (not biamped), and the wires between the top and bottom terminals are connected. Of course it's Friday so I can't speak to Kef support until monday mad.gif. Should I pull out the tweeter and see if a wire came loose in shipping? I was looking forward to using these speakers this weekend - this is kind of a bummer. Suggestions are appreciated.

Thanks!
David

I wouldn't touch them. I don't know KEF, but if the see they're tampered with...you might have an issue on your hands

I would inspect very carefully without disturbing anything, and if something like a loose wire or broken connection is obvious, you can fix it.

It is very unlikely that a speaker failed since it was tested at the factory, but freaky things can happen.

If the cause is not obvious, you had better wait and call KEF when you can.

Id say thats normal for a new, in production speaker, but the IQ90 is a bit old now and no telling if it was tested and more importantly how long ago. I'd just hate for them to say it was tampered with and that's why it isn't working. OR if you accidentally create damage upon taking it out and putting it back in. I mean...if you think you can take it out easily (I don't know what the iq90 uni-q looks like to remove) then do it. I probably would lol

Is it just the tweeter that's not working or the entire driver?

Just the tweeter. There is connectivity between the bi-amp pins, I checked it with a multimeter, so it is likely internal connection to the tweeter.

A broken internal connection/solder is not unheard of shipping damage.

I would wait to talk to KEF before opening up the speaker to keep warranty intact. KEF may give you clearance to open the speaker and check it out. And of course offering to replace it is a given.

+1

And sometimes speakers just have clip connections and the clip becomes loose.

*update* I spoke to KEF support today, they are sending me a new driver unit, which I will replace myself. I am glad I don't have to deal with shipping that huge speaker back. I asked the support tech about the build quality, which is now a concern, and he said this very rarely happens. I understand that things can get bounced around in shipping, so I will wait and see if the replacement does the trick.

Good to hear.

I wouldn't be concerned about build quality. Occasionally in shipping a box can just get really tossed about.

*Problem Sovled!*

Opened the back panel where the speaker wires connect, one of the blue tabs was disconnected. Re-connected the blue tab (pic below), tweeter is fixed! tongue.gif:p
