Hi all,I'm just about ready to cut the speaker-holes for my new speakers. I'm still deciding if I should flush mount the drivers to reduce diffraction effects or not. Flush mounting it is more difficult, because I must get the router set properly etc, and doing it for the 2370 horn is also more a pain in the ass. But I'm just not sure weather or not it will make a difference. From what I know, the diffraction caused by non-flush mounted drivers is not anywhere near as much as cabinet edge diffraction, interaction between point sources, and other parallax issues etc. I have the tools to flush mount, but its just a pain to do it. Any ideas? Thanks! Adrian

Looks from the JBL site that the 2370 is like the CH-3, etc. Make the cut-out that just allows the flange to sit flat on the baffle. Then, using a rabbetting bit in the router, rout the rabbett that sets the front of the flange flush. You'll have to trim the 4 corners sqaure with a chisel. Pretty easy with the right bit and a few test cuts. Also, the more I look at the cabinet Ing. Martinelli made with the recessed baffle, as well as the enclosure I'm doing for the 811B, I'm thinking all the BR speakers would look better and take a grill cloth better with the recessed baffle. Anyone want to tell me that a 15" JBL or TAD woofer and High Db horns are going to be compromised by acoustically transparent air conditioner filter or Antique Electric Supply vintage cloth or open weave black jersey? That take-the-grills-off stuff is just for the wimpy 5 1/2" "Mewlers"! It's not just that our HE speakers are big. They're boring. Check out what Garland did. Or the fellow that painted them Yellow and Red. Or, dare I say it, the double baffle on the woofer only on my 4Pi's. Or the combination of veneers and burls that Ing. Martinelli uses. These great huge boxes need some architectural interest. Or great paint schemes. Black textured paint, black cloth, black components, yecch!!!

Hey Wayne,I'll have a think about it anyway. It sounds like asthetically is where the real improvements are. When I come to cut the holes, I'll see how difficult it is and hopefully I'll put the effort in to flush mount them anyways. Thanks. Adrian
