So again, I revert to my original post. Looking forward to what Brian might have to say as well.
IDK, seems relatively straightforward, The frequency controls how deep or low the sub plays. Highest lets it play louder because it's harder to play those lower frequencies. Beyond the question of whether you just want the loduest it can be, the right setting will depend on your room gain and personal taste. Nobody can tell you precisely what your room gain is at any frequency, but you probably can pretty quickly figure out if you're getting overwhelmed at the low end with a lower extension setting.
Damping controls ringing. Ringing is the tendency of a device (like a sub driver) to continue to move after you stop applying a signal to it. It's kind of a spring, after all, so left to its own devices the driver will ring a bit. Using a sealed enclosure reduces ringing by putting air pressure behind the driver to fight the tendency to continue to flap after the signal stops. The damping settings essentially let you control the amount of flap. Based on simply reading the Rythmik website, it appears that lower damping (higher ringing) will allow higher ultimate SPL. A
fter that, it becomes, I think, a question of what simply sounds best in your room. My bias would be deepest extension, highest damping, because that should theoretically get me the most accurate sound from the sub. But if my room gain is too much below 20 Hz, I may try middle extension to get things under control. If I find I seem to be losing oomph on the loudest parts, I might try a higher damping setting to compensate.
Whether and to what extent the damping settings are audible and matter to you depends, I think, on your room, your ears, your experience, and your expectations. Although ringing is technically "wrong," I think, it can be at low enough levels to not matter. Plus, the real world things that get recorded (like a bass guitar or even an upright bass) are made of actual physical materials, not theoretical concepts, and they ring (resonate, sustain) too. So a little sub ringing may sound pretty natural to your ears, as it kind of adds to the instrument's (or noise's) natural "dropoff."
