Major Problems!! 1804 coming apart for no aparent reason, HELP! (1 Viewer)

[Chris Brock]

Well today I fired up the twin 1804 IB and was going to start doing some more tweeking with the BFD and when I was playing the low stuff below about 25hz I noticed this horrible noise coming from my IB. So on investigation and a removal of one of the drivers I found this!!!!!!!!!!!!!............

I put some toothpicks in it just to show how much of the surround actually seperated from the basket. It is almost half of the entire cone and some other areas feel fairly weak. I am only running these with around 350wrms per driver and I have only gotten max SPL numbers 1 time. This is an extreme shock to me because in all the crazy things I have done in car and home audio over the past 10 years I have never once damaged or blew a subwoofer. Is there anything I can do to fix this, or will it flat out require a recone? The sub works fine other then this issue. Any insight or suggestions would be greatly appriciated!!
Thanks!!
Chris

It's not damage, it's a failure of the adhesive.

No it shouldn't need to be reconed.

Send it back to Kyle and get it reglued, or have him send you the glue and instructions.

Contact me offline and we'll get things taken care of.

 

[Chris Brock]

thanks! Ill get you an email today Kyle. That is good that there really isnt any damage. For now I am running a single 1804 with the 350wrms and it is still unbelievable!!!

Perhaps you should consider a compression plate style mounting if it continues to be an issue, or just as a future precaution.

 

[Chris Brock]

hmm, that is a great idea. I might go ahead and do that then just to be sure. So far they have been mounted in the traditional way but if I mounted them from the rear all the pressure would help to hold things in place. Thanks for the suggestion!!

Adhesive failure. Shoulda used 3M

 

[Kyle Richardson]

I told them, you gotta use 3M....you just have to or else.....
They should have listened
