Also, I had never dreamed of a driver with a variable compliance resulting in a variable free air resonance... such a toy would be wonderful with custom midbass and bass horns...

It is why I use cone drivers for upperbass, use it as compression drivers - because I have a full control of back chamber and the driver resonance.  People, who do bass horns do not get that the drivers  themselves are as relevent as the driver-horn interfaces…

but let me explain the GOTO philosophy on this... they do not care to get the last bit of extension from any horn driver combination... their entire philosophy is to design a horn driver combination for four octaves and use the middle two... the area where the impedance curve and frequency response are extremely linear... they do push the two octave portion slightly toward the flare frequency from the middle, but that is due mostly to their preference for long, slow flares..

Yes, I can see it. I certainly disagree in many ways with what they do.

I have spent much time listening to these types of horns as well as thinking hard about the philosophy.... to me, when it comes to home reproduction, this type of thinking leads to not being able to horn load the bass as low as I would like... I would rather have the extra extension and not have to bring a direct radiator into the equation... in the home horn environment, which I truly believe to be superior to all other forms of music reproduction, we must choose carefully to be able to physically place the best setups into our smaller environments... I value time alignment and the goto philosophy allows for bass horns, but not with time alignment... they believe in throwing away that last half octave, at least...

Yes, I understand it.

I still would like to say that their drivers, with their extremely strong magnetic assemblies,ultra light and stiff diaphragms, and small exit diameters allow for the potenetial to be the best low mid, and possibly bass drivers currently available... if you would like, I will keep you informed on my horn experiments with these drivers... I have a pair of the 370's (400 to 18k) and 505's (100 to 6k)...
I never had GOTO driver and I never seen anybody rational who use them. Whatever I have seem and heard from Goto users sound to ridicules to me.  There was a guy in Sound Africa, he is OK from my point of view, and he used GOTO lower MF and upper bass if I remember correctly. He told me that he liked his Goto drivers a lot but I never heard his installation and therefore there are no common denominators for any judgment…

The next sing is not related specifically to the Sound Africa guy but my general attitude to the people talk about audio.  You see, people talk about anything and particularly within Internet anybody have point of views and experts assessments. My vote uselessly is not for the people who run mouth but who are able to demonstrate actual results – mean the sound of installation with noble objectives. Unfortunately the noble sonic objectives it is a big rarity and in many instanced people running around stadium are so behind that they begin to feel that they are leaders…

Goto might be good drivers but what would it mean “the best low mid …. drivers currently available”? The best horn divers are the drivers that the more perfectly serve the interests of a given horn. Anyhow, keep updating about your Goto journey. If they have a driver with 70-100Hz resonance I would try one for my upper bass horn but a driver with Fs of 24Hz will not work out for me. BTW, the extremely strong magnetic assembly is might not be… NOT necessarily be a good thing for bass horn loading.  For MF and HF driver it is good but for LF driver it is controversial. My experiments with electromagnetic drivers suggested the for bass drivers I would like to have as less as possible magnetic damping…
