I've gone back and forth on the ribbon damping issue, the short ribbon mics need to be damped but on the long ribbon mics I feel its a matter of taste and application. |
Sagging out of the gap?! Good grief!
Yes, the main disadvantage of the small ribbon is the compromise of tuning & damping.
I'm a big fan of the singe Hz range tuning, but, well, it isn't practical with most microphones.
Also, as you point out regarding sub-sonic rumble, if 'long' ribbons are tuned in the single Hz range (where they sound best) they can be a very very serious danger to both woofers & sub-woofers!
I've seen 'eye-popping' maximum mechanical excursion from a few 'un-protected' woofers from live-room door slam/kick drum wind on low-hz prototypes of mine. Oops!
