Hi.I have kept my Dynaudio audience 52SE in a box for a while now. Reason, was my then 2 y.o son was beginning to be inquisitive and he poked the tweeter, hence I have BOTH tweeter with 'dimple'. I've been using my KESTREL's and kinda miss the clarity and dynamic of the 52SE..
So, anyone has an idea how to do it? how much is the parts or where can I buy them (for cheaper than dealer)? any vid around if someone already did this?
Great job, Elizabeth. I could not have explained it better. Jastorg1, You can be sure tthis will work fine and your speakers will be restoreed to good health.
Vacuum cleaner suction can be tricky, placed too close and the strength of the suction could displace the voice coil. I suggest getting a cardboard tube from an empty paper towel roll, placing one end over the dimpled driver, and placing your lips inside the other end, and then gently suck. Works like a charm most of the time.
Those Dynaudio tweeters must look like clown noses to young kids. A friend's 3-year old poked my Dynaudio Contour 3.0 tweeter. He saw it, extended his index finger, and made a beeline from ten feet. Irresistible! But he was the only one laughing. I fixed it by bending a right angle with needlenose pliers in very tip of a pin, barely snagging the fabric in the deepest point of the dent, and gently pulling. The dent popped right out with no damage. Good luck!
Voice coil assembly can be dis-assembled from the back of the tweeter - VERY carefully these are fragile parts. You can then access the dome from the back and push it back into shape- if they have been sitting with dimples for a long time creases may have developed - and they can be very hard to get rid of - sometimes impossible.
Above only of course if your "smooching" suggested above fails to elicit the correct results :-)
It seems the first questions should be - is it audible?
If only one was dented, is there any sonic difference between it and the undamaged tweeter.
I used the bent (L shaped) straight pin once with a fabric dome tweeter, then applied a speck of glue over the tiny hole. But I've not had any success with the suction method. Perhaps I was being overly cautious.
I have a small dent in a stiff paper cone (Fostex) that I can't remove with mild suction. But I don't hear any difference from the other channel so I live with it.
I called dynaudio, they do not recommend vacuum cleaners, too much suction. They recommended a combination of scotch tape and suctioning with your mouth. Worked perfectly for me on a pair of audience 40's
I've had good luck with clear, 3m type tape...not the heavy duty packaging type...the kind found in offices, etc...or in severe cases...you can use the eraser end of a pencil from the back side...
been running music on the SE and I found that something is amiss with the sound (can only hear though on some recordings-- crakling like sound :( ).. Does anybody have any idea what are the chances of damaging the tweeter or how are tweeters arranged in sequence..
The question I had was once you're able to pop it back is the tweeter damaged even though visually the tweeter looks ok Are sonics effected once the tweeter is pushed in
Once a soft dome is deformed with a crease, it no longer behaves the same way under operation. What likely occurs are deviations from the original frequency response above 7000Hz where the dome typically starts entering resonance modes. The deformations and creases that might be in the dome now will alter those modes and change the way the tweeter radiates.
If you can quickly correct a poked in dome so that there are no creases, you stand a better chance at an unaffected speaker. If it hasn't been corrected for a length of time and creases permanently establish themselves, your best bet is to replace the dome assembly, which in the case of Dynaudio, an expensive proposition.
My buddy's tweeter was pushed in and then immediately came out on it's own there is still a crease but not sure if any damage was done I think these things are really delicate
He's debating whether to change his tweeter as a result
