Emile Posted April 12 Share Posted April 12 Haha; still have not found enough room for a K402 So, was looking at a JBL 2384 horn - see https://reconingspeakers.com/products-page/jbl-365359-001-2384-hornwaveguide-3732/ . However, horn exit is only 1-1/2 inch. Have several 2 inch CD's (and really do not want to downgrade to a 1-1/2" CD). Have some other JBL horns and the material thickness seems to be about 1/2 inch thick. Drilling out the exit to 2 inch would (only) take another 1/4 inch out of the material Anyone done this? Cheers, Emile 1 Quote Link to comment Share on other sites More sharing options...

Cheers, Emile you're gonna have to drill another 1/2 inch out of the throat , and yeah , that will work very well giving you the correct dispersion , to use with a 2 inch driver . 1 Quote Link to comment Share on other sites More sharing options...

Marvel Posted April 12 Share Posted April 12 Look around to rent a reamer to do it. Even a wood taper that you could wrap with sandpaper. A Dremel won't work for something like what you want to do. 1 1 Quote Link to comment Share on other sites More sharing options...

DJK once said that horn with a Beryllium driver was hard to beat. 2 Quote Link to comment Share on other sites More sharing options...

But just made someone an offer on 1.5" JBL2451H drivers Makes sense , no cutting , no messing around , but no way a 1,5 inch driver /horn is gonna sound like a 2 inch JBL 2360A which is on par with the K-402 , it's a compromise at best , and sooner or later , the 1,5 inch will go out the door . 1 Quote Link to comment Share on other sites More sharing options...
