I'm quoting your post to make a point that I think may be helpful for some people. I am really excited about the new subwoofers, and excited for some of my AVS friends who are already ordering them. I have absolute confidence that the new subs will be terrific!
One of the issues that I think sometimes gets overlooked is the range of preference that we see with respect to bass. Some people like to emphasize mid-bass frequencies more, for some content, and some people like to emphasize low-bass frequencies more for some content. The amount of room gain that someone gets will always be a factor in that, but the room gain won't change. And, as people turn-up the volume on their subs, all of the bass frequencies will get louder in the same proportion.
Those listeners who don't have a miniDSP to create their own house curves are somewhat at the mercy of the content, or to some extent at the mercy of pre-programmed software such as Audyssey's DEQ. In my opinion, one of the most important elements of the new low-tuned subwoofers will be the room size control (RSC). That will let listeners change the relative emphasis of mid-bass to low-bass, depending on the amount of room gain they get, and depending on their personal preferences.
I remember that when Jeff introduced the new low-tuned Cap 4000ULF and even the 14Hz port tune Cap 2400ULF, he ended-up increasing the range of adjustability in his low-frequency adjust (LFA) feature, in response to user requests. I believe that he went from a range of about 12db to about 18db.
I haven't heard Tom comment yet on whether that feature is changing at all in comparison to the range used on the older vented models, but I think it is something that is going to be especially valuable on the new subs. If you want to have 115db (or more) at 10 or 12Hz, you may not want to also have to listen to 120db (or more) at 60 or 80Hz in order to have it. People using miniDSP's, and playing with BEQ, won't care so much about this feature, but I believe that many people will find the RSC especially helpful with the new low-tuned subs.
I had been thinking about that as I read all of the recent discussion, and your post made a great segue to mention the potential importance of the RSC in getting just what you want. I believe that any of the 13.5Hz tuned subs will give you all the low-bass you will want. Now, it's just a matter of balancing your personal preferences for the proportion of low-bass to mid-bass, as you turn-up your volume.
