I just got a pair of used 2225H 15" woofers. I haven't put a signal through them yet. They are definitely used (cones are dusty, a little faded, even a little paint over-spray on one of 'em) but do not appear to be abused.
While unpacking them I could see through the vent screen on the back, a couple of pieces of "something" that actually looked and behaved like a couple of small slender plant leaves, or feathers, or "something." I didn't have time to get out the high intensity light to investigate further.
Any ideas what could be in that vent space? And how it might have gotten in there? And if it could be necessary to remove it?
I'm just curious and I know this forum can always answer JBL-related questions.
