Is it true it's a JBL woofer?

If so, what model #.....still in production?

Someone here has to know

I would like to know this as well. They are on the PRO C now I believe.

I don't know either, but the USD drivers did look like JBL's. Regardless though, they are clearly pro drivers.

Depends on who you talk to...Radian or Emilar.

Those two are the same company. Just a name change.

 

[thehatedguy]

I knew they had some shared history...but at that time, they were separate companies. I thought.

It was my understanding that it was a variant of the Emilar EL15D.

My PRO B 15s have different cones however.

 

[thehatedguy]

Do yours have the original cones or have then reconed? Some aftermarket recones can have slightly different materials...or the factory could have changed cones. Look and see what the Pro 15s looked like in the GN on the USD page...I thought they had ribbed cones but I could be wrong.

Emilar is still in business as Plus-One Engineering. Can find specs there. Well, they were last year when I looked...lol.

Those are the original cones. I've seen others with the ribbed cones but I did see a pair with the smooth cones and a USD logo on the dust cap.

Here is an old spec sheet if anyone was interested.
