Hi Wayne!

Thanks alot for the thorough reply! Well, I must admit that it's a bit over my head, which you, of course, can't be blamed for.

You have convinced me that alignment is far from being a trivial issue (at least not for me!).

You have also made it clear that the problem of (mis)alignment consists of a lot of different although interrelated problems. Some of these can be solved (e.g., misaligned drivers), while others are almost impossible to deal with (e.g., misalignmen due to moving membranes). If I get it right, then some of these problems must be more damaging to accurate sound reproduction than others.

Please correct me, if I'm wrong, but if I understand you right, then "time delaying filters" is not really a good solution to misaligned drivers, as they "solve" one problem (the time delay) by making a just another one (unlinear frequence response).

Assuming that this is correct, then misaligned drivers really ought to be avoided in the first place, right?

You wrote:
Is there, all other things equal, some frequency areas that are more sensitive to misalignment than others?

And finally: are the drivers in your folded horns aligned? (Please forgive me, but I don't know how the drivers should be arranged in a folded horn in order to be aligned with a "straight" HF horn)?

Thanks a lot!

Regards
Peter
