Default Magnaplanar SMGa - No Treble

Hi All
I had these Maggies stored for the last 15 years. Just tried them (they were the best speakers I'd ever had) and there seems to be no treble. The sound is sort of 'boxed up'. Was gonna put them on ebay but maybe they are destined for the trash....
Any advice please?
Thanks
Ron

Ronnie,
Are you driving the speakers with the same amp?

Is there no high frequency coming from the treble section when you put your ear next to it?

Your treble voicecoil is corroded and no longer connected. Worth fixing, if you ask me.

You haven't bothered to tell us where in the world you are, so it's a bit hard to give you advice.

If you are in the States - send them back to the factory, who will be able to re-lay any corroded drivers.

If you are elsewhere (so shipping is a problem), search the Planar Asylum archives for "delamination repair". Yes, it's something you can do yourself - but you need to get the wire kit sent from the factory. It's not difficult - simply tedious (I re-layed one of my mid drivers).

Regards,

Andy

Will take your kind advice and probably have a crack at repairing them myself.

Many Thanks

These are all good suggestions, but first, check the fuses.

Thanks

I did notice the there is some 'corrosion' around the fuse holders. I took one of the fuses out and it made no difference at all... the speaker just kept working as before (not very well!!)

Is that an indication of a problem?

I'll clean them and try again

Ron
