One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable,  This was some time ago now, I didnt turn my horns then, so I tried them on the original Hartfield horns with and without the "lenses".  which mainly obscured their sound.  I took them out of the Hartfield cabinet in order to have them sound in free space.  What impressed me about them was how low they would go, I once ran them with no Xover, carefully,  and they sounded very full.  I played with a lot of Xover points etc. until I got tired of them and sold the whole thing for a lot of cash.  It seems the diaphragms got missaligned on transit because the buyer said he was having some scratchy sound on one side, I instructed him how to realign the drivers a couple of times and never heard from him again,  I guess he was succesful.
A close friend had the 2441 with the Edgar 350 horns and they sounded very good also,  but the sound wasnt as I remembered of the 375s...

I said many times that I consider the JBL 375/2440 (it is the same driver) as a referees of all compression drivers. It is not that it is the best driver but it is very stable performer and it does serve good Sound (with new contemporary diaphragms) if it is properly tunes and aligned.
