Alas, so am I.

Of course we need to match woofer's and tweeter's off axis response. However HF drivers exist with any dispersion pattern under the sun (and absent something suitable simply design a suitable waveguide), so it is up to the designer to match the HF directivity to that of the LF.

Now just because this directivity (Index) is high for the LF it does not follow that there will not be a smooth transtition.

Well, what can say? You are preaching to the first apostle perhaps?

They do. I am quite fond of Coaxials, back to the old Schulze/RFT TH315 (developed from the first ever coaxial be Dipl Img Exckmiller) I owned i n the 80's.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
