View Full Version : 2440 bolts

03-08-2013, 03:37 PM
I have a pair of 2440's used in a PA system for some years. At some point one of the bolts holding the back cover was lost and replaced with a hardware store bolt.

I'm assuming that the only place to find these, if they exist, will be at JBLpro? I can take hardware store bolts and turn the head down fairly easily.

I also have a pair of 375's with the original diaphragm; the 2440's have 2441, probably aftermarket, diaphragms (pleated surround).

Phillips Fillister #10-32 UNF x 2"

Depending on the supplier, you may have to slightly grind the head
