Anything 2 beat a brahma?

Well the Brahma and XXX both have the advantage of our XBL^2 motor.  This means that they will have very low distortion up to it's linear limits.  If you are looking to get loudest at one frequency (SPL competition) then there are definitely better subs out there.  But from an SQL standpoint, IMO they are the best on the market only matched by the W7.

Well, i got immortals now, which are supposed to be spl-tuned kind of speakers. Kinda like strokers and stuff. I'm looking for something to play "Get Low" well when it drops to the 30 hz, you know? My subs simply get weak! W7s are EXPENSIVE and I am looking for something like "4 tempests will beat 2 brahmas" or something, but I dno not have room for tempests... you know. So they'd basically have to have a HUGE x-max and like no vas at all, lol. And a low bl and so on and so on... But is there anything to beat the, or are these the best? There's always something better thatn the best, so i'm tryng to find it before I spend the cash, you know. So, anyway... are the xxx really taht much louder? Is it worth the inefficiency? Brahmas'll hit 29mm with like 900 watts or something, as where an xxx won't, but will the xxx's 32 mm vs the brahmas 29mm make up for it? I do not have experiance with either sub... the best sub I've seen and delt with are my Audiobahn 2003 Immortals. Tehy are supposed to have a 29 mm x-max, but even if they did (which i doubt they do) the bl is like 10000000 on them or something, because they die on the lows, lol!

I was bout to say the same thing steven.  w7 is probably the next best competition.  Also look into MTX 9500.  Good sub too.  But JL's problem comes the price.  Great speaker (my favorite sub I've ever heard IMO) but a big tag on it.

A few comments.

I think you may be paying way too much attention to the excursion numbers.  Way too much.  Frankly, as long as they're in the same ballpark I wouldn't even look at them when coming down to making a buying decision.  Instead look at efficiency, evaluate the driver parameters against your preferred application in a program like WinISD, and try to find some sort of THD information.  Evaluate these against your pocketbook... repeat. 

Also, I think you may misunderstand BL.  A high BL does not mean that a speaker will not be able to produce low frequencies.  As I understand it, BL is the amount of motor force given x amount of current.  It is just one of the physical parameters of the driver that has an effect on efficiency and relative overall strength of the driver.  In my opinion it seems like a mistake to place much importance on the magnitude of BL when making buying decisions.  Now, as I understand it FLAT BL is important (hence the XBL^2 technology), but I'm not sure I'd care at all about small differences in total BL between drivers. 

Anyway, if you're going to start looking at these parameters then I think you need to consider them as a whole.  Use a program like WinISD or any of the other various box modeling programs to help you. 

This is my limited understand of the situation, pros, please correct me if I'm wrong.
