I've no doubt the JBL unit is better, but I had to draw a line on the budget somewhere and it was more important for me to get the best treble, so the B&C DE250 was a must have. Now if I was going for the 4 Pi, then I suspect the JBL would really come into it's own as it is doing more work. All the problems I now have in the bass region I suspect will be sorted out with better output transformers in my Bottlehead amps which will provide better and tighter bass control.I've not started the re-build of the mid-horn yet (a project for this summer as I'm still using my outdoor workshop) but the main reason is to put together a slightly larger flair, but also have it completely exposed, with just the drive unit enclosed in a box (any thoughts Wayne?).
Yes, satisfied enough to want to listen more than tweak or build or change or.....
