What do you guys (gals) think of this?

BTW, I did read up on how to repair the MMG's through some of the threads here. But I was wondering, if the wires are held in place from residual stickiness (I cleaned the area with acetone) just enough to secure with scotch tape, why would this not be a permanent fix?

Originally, while attempting to fix (or further ruin) my Gamut amp...something went haywire, and I started smelling something burning. By the time I realized that the smell was emanating from the speaker...the wires (from the heat) unglued themselves from the mylar diaphragm, but only from the middle part of the panel.

Seems to be working fine. No vibrations at all. I don't think that there would be a weight issue with that little amount of tape eh?

Thanks

<bump>

...is it "not cool" to bump your own thread? Hell, If anything maybe I'll get a response to that question...lol.

repair?

can you kindly post a pic of the repair you made without the tape?

 

[aptquark]

Mavric...thanks for the interest.

Well, I didn't take any pics before repair...I'm trying to get into the habit.

But basically the wires got VERY hot and unglued themselves from the diaphragm in the middle part of the speaker. I was deciding at that point whether I was going to try to repair OR use the speaker as an upright bass! HAR HAR!

After cleaning the area with acetone, there was still a residual stickyness...so I realigned the wires...and used the scotch tape for temp solution. The damn thing works like normal. I'm just wondering if there are certain principles effecting sound that this is contributing that I am not aware of. Any ideas?

thank you

I think like your first experienced, HEAT is a design and material consideration.

I think there is a special glue for this which you should be using, but it needs to cure/dry before using or a fire will result.

I think you should contact Magnepan about the situation and see what they say.

Yes, I will call the Co. you are right about that. The only problem is I think they know me by now...and they don't answer the phone.😀

Well, by using tape you are incresing the mass of the membrane, which will affect both sond and will be meassurable.
The tape will also have a dampening effect. You will probably have a little less output at hig-mid feq.
The tape will almost for sure not last, and you might start to get a mecanical sound from the wire moving but not entirely together with the membrane ... especially with hugher volume....
I would go for gluing them as proposed by kach22i
Beat regards Baldin 😉

Yea...I figured that this is what I would eventually do. Just was more into the theoretical aspects of scotch tape science. 😱
