JBL 476be/435be

[subwoof]

If you look at the nose on the ebay 2451's ( they are real ) you will see that 4 additional holes were drilled into the 2450 snout ( that also had their magnet cover flanges cut off ) to allow custom LONG bolts to hold the snout to the magnet. It's a whole lot safer to redrill the aluminum snout than drill/tap the super strong magnet. I did it to a pair and it was an exercise in chip management....

The 2450 and 2451 use the same magnet BUT the horn mounting holes on the 2451 are standard whereas the mounting holes on the 2450 magnet are for the snout ONLY and are much wider spaced.

Back when I had many of these variants in the shop I photographed the differences and if I find the pix I will post.

Thanks for replying, subwoof.

Yeah, I did notice that, and was guessing along those lines.

"(that also had their magnet cover flanges cut off)"

I don't follow you on that detail. I'll go back and look at the auction again.

**** I see now. I looked at these, then to the JBL data sheet and see it noramllly comes up around the magnet and would cover the 2451 label had it been left on.

"I did it to a pair and it was an exercise in chip management...."

Any chance these are the pair you made?

I haven't decided yet whether or not I am going to sell my personal pair of 476BE's. They were awfully difficult to obtain and I might use them for something someday.

I have this drivers in my speakers JBL 2254j/2251j/2435hpl and 045Be
This is hornloded speakers with this crossover point 300Hz/700Hz/10kHz

Hi Ari,
Can you please tell me what kind of surround is used on the 476Be? Is it diamond pattern, fabric, etc? I have not been able to find a good picture of the diaphragm.

I'll pop in here.
The 476Be has the 4" diamond surround just like the other newer JBL 4" diaphragms.

Thank you. It was difficult for me to find a picture of it on the net.
