The Rythmik subs went up a notch in my personal recommendation list after this last meet.

BDP24 you need to go to a subwoofer meet. 18" subs don't lose anything in the sound quality arena to even a 10" subwoofer. A 20hz note means the subwoofer moves 20 cycles per second. A 10", 12" 15" and 18" subwoofer must all move 20 cycles per second to make that note. What the big drivers do gain is significantly more air displacement capability -- which leads to more of what you like at greater SPL. The 18" subs we were auditioning at the meet, were not the typical mobile DJ PA low cost subwoofers...
Archaea---I would love to go to a GTG, but there hasn't been one closer to me than Northern California (about an 8 hour drive, and I don't know any of the fellas up there). I especially want to hear, of course, the TC 5400 in a medium sized (4 - 5 cu. ft.) sealed box. I would consider having one in the same room (2470 cu. ft., sealed, carpeted, and tube trapped) with the GR/Rythmik Open Baffle pair that I am putting together to run under my Electrostats, and the Rythmik H600/DS1510 pair that I am also about to receive from Brian and put in 4 cu. ft. boxes to augment the OB's. That may surprise you, as it appears you missed a couple of words in my post about the 18 inchers and the testimonials to them....."may or" from my statement about them (the 18's and the reports on them, that is). It's not that they may be better, are better, could be better, etc., than a Rythmic or any other sub you care to mention; it is, rather, that from the source material used and the comments made in the reports about the big subs, I have no idea from what was said in the reports if I would, or even just may, want one. What I listen to, and for, in a sub, are completely different from the things which are mentioned in such reports. And, contrary to the Politically Correct assertation, that excelling at reproducing movie sound effects automatically means that the same sub will excel at reproducing music, well, it just may be that what makes a sub good at doing one may not make it so good at doing the other. Further, that which sub is best for any given listener may be determined by what characteristics and qualities that listener requires from a sub, and that different subs have different strengths and weaknesses that affect, and perhaps even determine, their appropriateness for any given listener. As I haven't heard a TC 5400, I can't say if I think that it does some, or all, things better than all other subs available (as some reports have claimed). Nor do I think it needs to for me to consider aquiring one (or two!) of them. "18 inch subs don't lose anything in the sound quality arena to even a 10 inch subwoofer" you say. Nothing? Not one of them? I take it you've heard every 18" and 10" sub available. As I said, I haven't heard a TC 5400, but I am quite certain that the GR/Rythmik OB and/or Rythmik F15HP subs may do atleast SOMETHING better than it, in a way that might make it/them preferable for the use to which I put them, that of reproducing recordings of Baroque (piano, organ, harpsichord, double bass, cello, voice, etc., and Bluegrass (double bass, guitar, dobro, mandolin, voice) music. It could also be that the way in which the TC 5400 truly is better than any other sub---the lowest frequencies at the highest SPL with the lowest of some types of distortion---is not a characteristic that I require in a sub. And that what a Rythmik is best at (everyone is free to insert whatever he or she considers that to be), is. But that's just me.
