Difference? 044 vs. 044-1 tweeters.

[briang]

OK gang, for the new guy, can anyone answer what the difference is between an 044 tweeter and an 044-1 tweeter (other than the 044-1 diaphram is goldish in color and the surround is black instead of polished aluminium)?
Thanks in advance

If memory serves, the -1 is rear-mounted and the regular 044 mounts from the front...

OK, I have both in front of me now...they look the same (both mount from the back) except the 044-1 is tinted goldish and painted black. Anyone know if they spec out different?

Can't confirm where I read this, so take as a suggestion. Aside from the cosmetic difference, the 44-1 did not have the very fine metal deposit coating as with the 044 and 066.

They are electrically and acoustically the same.

Just to recap-

044 has silver frame with silver diaphragm and tapped bolt holes (bolts pass through baffle to mount).
044-1 has black frame with gold diaphragm and drilled out bolt holes (wood screws mount unit from inside the enclosure).

On my 250ti, tweeters have silver diaphram ans are marked 044-1 on the back.
By the way, any idea about the way to open them to check the foam inside ?

Then someone put 044 diaphragms in.

044 diaphragms are NLA.
044-1 diaphragms are still available.

Take off the screen and undo the four bolts holding the magnetic assembly to the frame.

Thanks for your answer.
I don't understand how the sceen is fastened on the unit.
I don't want to spoil it.
Do I have to pull it ?

I don't understand how the sceen is fastened on the unit.

It is held in place with a rubber gasket. Sometimes JBL also put a bit of adhesive underneath the gasket to help hold it in. Carefully pull the gasket out of the groove and then pull off the screen.
