Duke - I started out with the JBL woofers that were native to my L-200 which are the LE15B. Bill suggested that I would get better efficiency and a lower XO point by switching to the RCF L15P530 drivers. These, by the way, were a nightmare to locate as they had already been discontinued by the time Bill recommended them to me. It turned out that they had been bought mostly for car stereo subs even though that is not what they were originally designed for. The replacement apparently was not as good according to Bill.
If I ever get to the point of selling my horns, I have a vintage pair of 12 inch drivers that I will use as single drivers in a simple cabinet - so I guess that's my answer to the original question.
