Reading the description of your room reminds me that we will all be deaf someday. We had a lot of fun getting there though.
I wonder if you have more output down low than Luke? I was recently in his room, and it was insane but nothing to change my mind about the really low stuff.
I still think most people (in non bunker rooms
) would prefer an Orbit Shifter over a 2400. A friend of mine recently compared a 4000 to his dual OS's an he liked the OS's better. Like you say though, we all have different preferences.
I think it's interesting to hear different perspectives on this. But, count me as one of those who would prefer subs that are tuned low, in a big space on concrete. We used to talk a lot on the Nearfield MBM thread about susceptibility to tactile sensations. For instance, some people seem more susceptible to chest punch than others. And, I believe that room construction can enhance or inhibit that effect, with dense wood paneling for example increasing tactility. I have that in my room.
But, on a concrete pad, it can take a lot of low-frequency SPL to hear, and especially to feel, what we may want to experience in action movies and blockbusters. Some people, like yourself, use Crowson's or other tactile transducers to enhance those effects. But, I enjoy getting the effects with my subwoofers. And, if I really want to, I can make my concrete pad ripple with low-frequency energy.
As MKtheater noted, ported subs are a whole different animal when it comes to low-bass tactile sensations. I honestly think that for most people, achieving adequate mid-bass is fairly easy, although even there some people want additional mid-bass tactile sensations, perhaps for reasons alluded to earlier. Most of the subwoofer upgrades I see on the forum, though, involve people seeking more low-frequency SPL. Jeff is an innovator, but he also follows his customer demands. If the demand were for more mid-bass output, he would be selling more Orbit Shifters, and spending less time developing Cap 4000's and low-tuned Cap 2400's.
I think that you have an outstanding bass system that took you a lot of time and effort to develop. And, it's one that suits you very well. But, if you were starting from scratch today, and wanted to simplify your life, I suspect that dual Cap 4000's (or perhaps even two or three Cap 2400's) could probably get you very close to the same level of satisfaction that you feel now. I remember your positive impressions when you tested just one Cap 4000 in your room.
I really do think that individual user preference rules, and that some people will inevitably like subwoofers which are designed to emphasize mid-bass frequencies more than low-bass ones. But, my own preferences are for ample low-bass. In a smaller room with more room gain, or on a suspended wood floor with more transferred tactile energy, I might find myself wanting to back-off the ULF. But, in large rooms, on concrete, I think that most people are likely to opt for more low-bass SPL and tactile response.
