Of course I am not really talking about Rullit but only holding up his implimentations against his stated aims. This is certainly no special case, since most smart people learn the talk and the "look" long before they learn practicum, if they ever do, and most people will finally settle into what pays the bills, in any case.
One thing that appears obvious in Rullit's designs is that the sound will be subordinate to the idiosyncratic materials and constructions of choice. Of course (again) I have not listened to this stuff, but I have listened to a LOT of drivers over many years. Anyway, my educated guess is that there are less spectacular ways to do what needs to be done with compression drivers by developing what is perhaps more readily available, "generic" material.
One thing that came out of my experience with "FR" drivers is appreciation for what a truly wide range driver can do. Simply put, I believe the idea here is to get as much range out of this driver as possible without making it "idiosyncratic". I am not sure, other than horn size, why the bottom would be cut at 500 Hz? Not arguing (how would I know?), but genuinely curious. Sure, the natural response will be humped, since that's how it goes (best case, one smooth hump); but that's what the other drivers are for, even "taking advantage of weakness" by contributing to lower output ends. Looking back, I keep thinking one might critically tune a not-so-small diaphragm/throat to have quite a wide useful range. Since tone always gets lost at LF, why not trail "MF" to 300 Hz?
