Having Cubo 12 problems........(SOLVED)(SOLVED)

Are you absolutely certain it's the speaker making the sound?

Once had a similar damaged-speaker-sound coming from a cabinet (think it was a Cubo 15), it turned out to be a screw dancing on the cone.
Obviously that isn't your exact problem but it indicates there might be something else vibrating in the cabinet creating a very-much-like-a-damaged-speaker-sound.

have you built one or two cabs.... do both have the same issue with the drivers......

the box is locked air tight...there is a rubber gasket between the speaker and the speaker mount...

at what frequency are you crossing?

Have you tried more than one driver in this box, if so are they all making the same noise?

i checked all the reinforcement in the box and all braces and struts where firmly intact. i built it with 3/4 mbf icould be the problem?
thank you...

I would guess you have a leaky cab. Check your handles, tophats, plates, etc. Get some silicon and seal the sh!t out of it. smiley20

i have no handles, tophats,plates on the box...the inside of the box is totally sealed up with liquid nail...

i would still run a bead of silicon or 'liquid nails' along all the ends where panels meet. Remember that most construction glue isnt really meant to be airtight, just do its job
