Post Subject: X-Over Point in 250 Hz Horn; Diaphragm compositionPosted by boiklox on: 1/17/2014

@Mats -- Thank you! This has already been the best sounding system I have built and designed, but hearing how good it sounds, lets me know how good it can be in the future. Thank you for the info on the JBL 2482. I've considered swapping the diaphragm with a Be 'phragm, but the phenolic also sounds like a good idea.
I think I will drop the x-over on the 2445 at least by an octave this weekend and see what happens. I'll have to run the 2445 a bit higher than 2k for now, since the 2405 won't go that low.
But also good suggestion on the 1" in a 600 Hz horn to fill that gap.

@Klegind -- Thank you for the info on the 2482. EQ is not something I want to do, so maybe I need to push the 300 up to 500. We'll see how it measures. I also thought that the "rule of thumb" was to have the x-over about an octave higher than the horn cutoff.
@Mats -- Interesting on your system, I'd love to see what you've built and how you've designed the electronics. Do you have a build-log here on this forum? Good idea with the PLLXO, I've not thought about approaching the x-over this way.
