AND, is there anything that I could do to the box to make it go down lower than 25hz?
Apparently not a quick answer, lol. I have not seen the answer to your question, perhaps because those with measuring equipment are focused on high end subs. And there really isn't one answer, since room characteristics, sub placement, adjustments/smoothing, and volume all affect what you hear/feel. But if you find data on how low it goes, please come back and post it!
Many people have commented that the F12 goes deeper after it's been played 50-100 hours. That's a topic of controversy, but in three weeks, I have noticed a difference in resonance, dynamics, as well as sensations of pressure, and the number of objects rattling in the adjacent room went from zero to dozens.
When I did my sub crawl, the volume seemed low, and mostly dull thuds, nothing delicate about delivery. But after I set up Audyssey (MultEQ XT), within an hour, it started showing personality, resonance, dynamics. While people argue the break-in is your brain adjusting, the difference I notice is more what I feel, not what I hear. Brain tricks don't cause deep chest vibrations/pressure sensations, changes in harmonics, or in what rattles and for how long. The F12 still sounds dull with MP3 level audio and TV popups. But if it lacked musicality, movie scores wouldn't sound as great as they do. I attribute dullness to the source.
Three weeks ago, Star Wars-Clones shook us, the chair, the floor. We felt the pressure in the chest feeling others talk about when they describe frequencies below hearing. Now, there's a great deal more of that. I take that to mean it's going deeper now. I don't know how deep, but it doesn't matter to me, as long as it does what it does well, and improves the listening experience.
