Oh definitely.This is awesome. It's great to see them compared in the same box, same room,
I had a very similar thought yesterday and wondered about some of the currently available woofers out thereToo bad you didn't have a modern driver to try out also. The closest Satori I could find is a 9.5.
9½″ SATORI WO24P-8 / Paper - Sbacoustics
Hard paper cone for improved piston operation (made in-house), large optimized motor system with under-cut pole piece and dual shorting rings.sbacoustics.com
I will measure after work tonight and let you know. I can remember.Kool experiment. I have some 12" Maggies . What size is the baffle 18x32 or so?
High Qts, I would imagine = "good for open baffle", you know?To my surprise the Jensen had the most bass output, it is the lightest and has what seems smallest magnet, but it is alneco as all but the Rola are. It may be the best suited for open baffle or a lossy enclosure.
It would be nice to have one of those gizmos, wouldn't it? I keep thinking about getting one...Well Mr Hardy.....
I was wishing I had woofer tester yesterday to use.
As for hanging from the trees, I'm not quite ready. 😏
Fun in your own backyard!High Qts, I would imagine = "good for open baffle", you know?
This is very cool, especially because these aren't the kinds of drivers that usually get assessed in an objective way -- other than maybe T/S parameter measurements.
The "problem" (i.e., the wrinkle to analysis) is that the electromechanical properties of the drivers will, to some extent, (differentially) color their behavior on an OB (or, of course, in any given enclosure/alignment).
I guess (???) the fairest way to evaluate them might be to hang 'em from a tree or a stepladder somewhere outside, in free space, and do similar measurements -- or to crank up one of them "Klippel" things that does soundfield measurements and can back-calculate anechoic performance from data generated in (almost?) any environment.
This isn't meant to be (overly) critical nor demotivating at all. I am just sayin'.
That said, as always "The perfect is the enemy of the good"; this is infinitely better than what I/we knew about these drivers, say, 24 hours ago!
Thanks!!
