I have two JBL D120 reproductions built from original '70's D120F orange baskets/alnico magets that l would like to sell, but have a little problem - when I took them out of the speaker cabinet they have what looks like glue on the dust cap covers. For me to sell the speakers, I need to know what this is, what it means and if it's possible how or if it can be removed.
Picture attached
Thanks
'Looks like someone barfed through the grille.It's likely water soluble, but how you'd get it off without risking denting the domes is beyound me...

You have a soft brush like women use for facial make-up?? You may be able to just gently brush it off.

LOL! That speaker was actually the one on the bottom of the cabinet which made it in reach of the cat! I'm going to now remove the top speaker and see if the cone has this same stuff on it or not.
The top speaker dome is still in emmaculate condition as both speakers' domes looked when I bought the pair two years ago. And there are no signs of anything on the outside or the inside of the grill cloth directly in front of the speaker with the dirty speaker dome, therefore, this must be a coincidence and not cat barf, but some other substance. If it were barf, then why is it only on the dome and not on the paper around the dome? The thing is, it sounds as it should.
There's no telling how that lovely (rare, and also quite valuable) patina got on the dome during its use in the last original Greatful Dead tour....
Seriously folks, no one in this forum has even an inkling what this could be? Maybe I got it right the first time calling it something from the planet jupitar.
I was serious!
They may have cleaned it off the grille, but not the speaker.Originally Posted by johnaec

Technically speaking? I still don't get it. It sounds like
you're suggesting that a mysterious cleaning man helped himself through the door to clean my speaker grill and afterward removed the speaker and cleaned the inside of the grill, replaced the speaker and then quietly let himself out. Because besides myself, there is no one living with me who would have any reason to clean my grill and when I question them about it, not admit it. Whatever.
looks like muddy water to me. maybe the water soaked in to the cone and the dried
stuff stuck to the dome and shook off the cone for some reason (during play). have you
tried a light mist of plain water and dabbing kleenex to see if your gunk is soluable without
resorting to harsher chemicals or scrubbing?

Nothing happened to the speaker while I owned it. I bought it reconed from a former JBL employee whose job was to build these speakers in the JBL factory. It looked to be brand new when I bought it a year and a half ago, both the paper and the dome. Is it possible, you are saying, that the former/magnet assembly under the dome had muddy waters in it? (not the guitarist, the actual muddy water)
yeah, not "Muddy Waters"Is it possible, you are saying, that the former/magnet assembly under the dome had muddy waters in it? (not the guitarist, the actual muddy water)
The dome's aluminum and it's unlikely that stuff would just grow on it and run down the
front of just the dome. That does appear to remain a mystery. Then again, I don't have
experience playing in very humid environs... dried fungus or mold?
The gunk does appear to simply reside on the dome surface... I was trying to slide the
conversation into what can be done about it, assuming you're interested in attempting to
clean it up w/o damaging it. You could also consider having a qualified reconer just replace the dome if it's troubling.
Someone else can ask you to smell or taste it (purely in the interest of science).

My guess is the cat was spraying the cabinet. The urine soaked into the cone but dried up on the cap. What does it smell like?
Horsehead, I agree with John W that it looks like the cat hosed it down. Whatever it is was liquid, and left the solids when it dried. The liquid ran to the lower right (probably 6 o'clock when you had it installed), and there is evidence on the cone in the lower right also.
I would attempt to clean the dome with Q-tips moistened with water and the excess blotted off. The dome is only 2 or 3 mil thick, so move the Q-tip very gently back and forth. Multiple passes will work better than downward pressure, and give the encrusted areas time to dissolve. After a half hour so of fiddly work you should have a clean dome.
O.K., O.K., DON'T listen to the Zilchster, then....
