Jbl 4410

Hyldal · 4th September 2007, 09:28 AM

I hear this old speaker lately, and there were some things in the bas that impressed me and I feel is difficult to find in modern speakers. The bas range was very transparent.

Does anybody have the TS-parameters on the woofer?
Does anybody know the type number on the woofer?

It's a JBL127H-1 12" unit.

T/S-parameters here: http://www.jblproservice.com/pdf/Thi...Parameters.pdf

Sorry EspenE the driver is only a 8 or 10", and the other drivers are a 5" and a 25mm titanium dome.

The 4410 uses a 10" driver.

You are both right, of course. The 127H-1 is a 10" driver. Slip of the finger.

The other drivers are a 104H-2 and a 035tiA titanium dome. The latter was replaced with the 052ti in 1993 or thereabouts.

Ok, EspenE thank you, do you know where to find the TS parameters on the woofer?
