Based on what MK said above, the mid bass impact should be the same as Imureh is no where reaching the limit of his FV18’s pair in his room. If that is the case then those extra outputs above 40hz from the v3601’s are moot. I am real interested in reading Hop’s take on this when he can compare his dual 2400ulf’s.

I’ve read nearly every thread on this subject, and tried a couple MBM’s nearfield for a year before adding a pair of DIY subs behind me, but I haven’t ever experienced a truly killer system like aforementioned. That said, I’m more about deep bass TR...just curious.
I am also very interested in hearing more subjective comparisons of the PSA subs and the JTR subs (although I have already heard several people describe their subjective impressions). But, when we talk about how much mid-bass is enough, or how much low-bass is enough, I'm not sure that we always make the correct distinctions with respect to what "enough" actually means. Are we talking about enough SPL
, or are we talking about enough TR
, because those two things are not identical.
For instance, some people can't seem to get quite enough low-bass TR from their subwoofers no matter how much extension or SPL they have. Even with suspended wood floors, and low-tuned ported subs, they still want MOAR, so they add Crowson's or other TT's, to get more of the deep rumbling, shaking, thudding sensations they want.
Similarly, some people can't seem to get enough chest punch to satisfy their personal tastes, no matter how much mid-bass SPL they have. So, they add nearfield ported mid-bass modules (such as the Behringer B1200D) specifically to increase the chest punch sensations they feel. And, sometimes even implementing those additional low-bass and mid-bass measures still doesn't seem to give some people the same sensations that they hear others describe. In my opinion, a lot of the difference in the sensations lies in us.
I am not sure what Hop will find out when he has both Cap 2400ULF's up and running. Everyone is different, so it's hard to prejudge his personal subjective impressions. For most people, once we have enough mid-bass SPL, at our preferred listening levels, we can turn our attention to the low-frequencies, and increase our SPL for frequencies below 20Hz. But, again, everyone is different, and although we can make generalizations which may be valid, they certainly won't hold true for everyone.
If we make any mistakes on threads like this one, it would be in assuming that the experiences of the people who are doing the comparisons are directly relevant to our own situations. The room sizes, subwoofer placements, and subwoofer capabilities can be directly relevant, and yet our own perceptions and preferences can still be sufficiently individualistic to negate some of the relevance. I think it's important to periodically remind ourselves of that, because we see examples of our different perceptions and preferences all the time.
