Blvdre Posted November 29, 2009 Share Posted November 29, 2009 BrushWellman,, Who supplies berylliam diaphrams to JBL,, At the end of this month will be making berylliam phrams available for other drivers such as JBL 375,,2450,,2445,, (4" diaphrams) and they announced suppling phrams for the JBL 175,,Le85,, 2410,,2420,,2426,,(1 3/4" phrams) Hmm, I could replace the old aluminum phragms in my 2420's. Any idea on cost for the 1 3/4", Maron? In general, do the beryl's reach as low as the original aluminums? Quote Link to comment Share on other sites More sharing options...
Invidiosulus Posted November 29, 2009 Share Posted November 29, 2009 I made a small ugly 4 sided conical horn this evening and put it on one of my heresy's. It sounds nice. -Josh Quote Link to comment Share on other sites More sharing options...
