View Full Version : 2305 Lens

Sorry if this has been addressed elsewhere, but I didn't discover it if it has.

I've come into possession of a pair of 2305 horns/lenses: http://www.lansingheritage.org/images/jbl/specs/pro-comp/horns-lens/page2.jpg

I was surprised to find what seems to me to be an enormous amount of felt dampening between the individual perforated plates.

Is this how they were originally constructed, or was this added somewhere along the line as attenuation?

Thanks for reading/responding.
