Who knows. If you address the particulars well enough they can give the basis for something quite interesting.

I see you are cherrypicking again what wish to quote and what not.

What I did actually write that first it was neccesary to equalise the severely non-flat response of the Drivers, in our case we combined acoustic means (short rear horn at LF) and electrical means (LCR Traps). Once this is done the resultant frequency response is flat and the off axis response by far better than you think.

Many modern "Mid-Bass" drivers also have a severely non-flat response that must be equalised. If you listened to them without EQ you would amazed just how bad they sound...

You can of course just use a normal line level equaliser and do the same.

Did you take care to equalise the system for flat response before listening? Otherwise I would be unsurprised.

Again you ignore most of what I wrote and cherrypick something that you can use to be negative. What I have described is not only possible, the results are quite good, good enough for me for example to call the D130 "The Best Mid Bass Driver ever", though the 15" Tannoy Monitor Red, the 15"EV SP-15 with Alnico Magnet and the old Alnico Magnet Altec 604 run it a more than close joint second.

Just get over it. You do not know all there is to know in the world (neither do I, though it seems more than you on the topic).

Stop insisting that white must be black because you say so (and because you lack the understanding to see that what I called white was white) and you may find we have more views in common than apart, though I tend towards a far more narrow directivity as desirable than your key source and that for very good reasons.
