Warning to the wise, don't let your 5 year old nephew near your speakers. After getting back from a trip to Pennsylvania, I found my tweeter had a nice little dent. Poking fingers and tweeters don't mix. I posted some photos and was wondering if there's any remedies. Any help or suggestions would be much appreciated.


Speakers are Infinity Beta 20 bookshelves. Material is CMMD

Working in collaboration with metallurgy specialists, the resourceful Infinity transducer engineers identified a special combination of materials that exhibit a remarkably useful set of mechanical properties. Infinity's new Ceramic Metal Matrix Diaphragms are much stiffer than standard metal diaphragms, moving the natural modes significantly upwards in frequency. At the same time, CMMD cones have more damping than metal cones, making this an excellent cone material for all transducers: woofers, midranges and tweeters.

The dent should not impact tweeter performance but try gently massaging the edges, it may pop to original shape. Also try cellophane tape (sticky side to dent and remove). Might have to do this a few times. One more - use your vacuum cleaner's hose attachment to suction out.

I'll give them all a try. Thanks for the quick reply

Personally, I would leave it alone as long as it sounds the same as the other tweeter.

I have to disagree about the massaging. I think that can only make it worse.

This is how I fixed a similar problem with a woofer center cap that a kid had pushed in. Use a vacuum cleaner nozzle. Be careful not to apply too much suction. It helps if you have the kind of hose that has a variable opening to bleed off some of the suction.

This is the main reason I have my speakers mounted up high, to keep them out of harms way.

The tape thing has worked before.

And put the grilles back on the speaker if you have prying little fingers around...

How did this work out?
I have a Beta C250 with a dented tweeter. It looks almost identical to your picture.
Please let me know so I can try on mine.
Thanks

I had the same issue with my Dali speaker. I tried several differant types of tape before it worked. Duck tape works well too, once out peal it off, not pull.

Life is enjoyable with good quality
