I bought a pair of really nice JBL 2441 drivers this weekend. One of the drivers has about 5 short cracks in the plastic throat and that can be seen with a flashlight and felt with your finger. Will this create an issue with performance and if so, what can one do to remedy?
throat cracks are not a huge deal, generally. They can be replaced but the driver needs to be demagged and remagged to do it.
Turns out the cracks are manufacturing cracks and should cause no negative effects according to the tech at Speaker Repair Pros in CA.
I've read they can be replaced.
Not aware of any plastic parts in DRIVER throat, do you mean a plastic
HORN throat that's bolted on?. What model horn?. Pics of cracks?.
Sorry guys. No this is not a plastic horn. It is a JBL 2441 compression driver that has a throat inside the driver that I believe is made from bakelite. I'm not talking about the horn, I'm talking about the driver.
Guess I should look at mine sometime.
My guess is that the cracks may have little audible effect -- but that's a SWAG (at best).
all the best,
Must be modified or a cheap import knockoff.
No, the tapered tube inside the driver between the phase plug and the opening is either plastic or Bakelite. I have seen them broken before.
He might be able to work some epoxy into the cracks with his fingers.
Get a new horn for it (them)!
I am not exactly objective, but the JBL 2441 pairs awfully nicely with the EMILAR EH500-2 horn.
Big-boy horn sound at a relatively modest price.
all the best,
