Certainly, data/measuring can't bridge the gap psycho-acoustic gap of interpretation, and subsequently putting into words like the "character" as you said. The science is mature, but it would be somewhat naïve to think we've exhausted all
the advancements in audio measuring.
The drivers you mentioned do seem to have a high subjective appeal and oftentimes are praised for their characteristic "speed, punch", etc. Why? I've got my suspicions but I'm not entirely sure. I know for a fact the TD12 design, when properly employed in the fast bass
of approx. 50hz-200hz, in a decent room, results in world class coverage of that range.
I have 6 of them used thusly. I've experienced many world class loudspeakers in highly optimized environments, and those AE drivers are tough to beat.
Decadent Spectre, you may or may not have read this, however I believe you would find it interesting. The discussion never fully took flight. But knowing the relationship of inductance, and an amplifiers ability to dump high levels of current into said inductance, is a factor in bass reproduction, I wanted to explore the topic further. The thread is over at Data-Bass, can be found here
, and contains some other of my fave topics too, ... namely LRSE
.Latent release of stored energy
... in one form, is something I'm grappling with theoretically, and subjectively in use. I own both a quad 18 IB, and two, double 15 small sealed. So both sides of the theoretical LRSE coin. Although the IB is still considered within the sealed alignment, when executed ideally, the resulting sound is different than typical small sealed subs. One differentiating factor is the low drive levels (low compression) needed relative to the high power levels needed with small sealed. But the other factor is the LRSE, and the freedom at which the cone isn't significantly impacted by the back-wave energy. I digress...
