if LABS don't go low enough for you there are two choices:

make some boxes to go under them. your options would be bandpass boxes like the Funktion One Infrabass; something like the danley PB12 (or see Walt's stepped horn); or a very long piece of sewer pipe with a long excursion driver on the end. other options are either too expensive or too large IMO.

try a Waves Maxxbass. some people are sceptical that it's not REAL bass but sounds good to me. for example 20Hz is reproduced as a combination of 40Hz and 60Hz tones so there is still a lot of air being moved. At the gig I did last week my 40 Hz boxes sounded flat to 25Hz with the Maxxbass and a little room gain. at about $300 it is certainly a lot cheaper than several extra speakers and amps to occasionally reproduce sub 35Hz material.

Yikes Maxxbass is using side band generation, that means you get.

20Hz, 40Hz, 60Hz, and 100Hz Simultaneously.  That doesn't sound very harmonious to me!?

Phil,
My point was that for live work.. it would be better if one didn't try to reproduce below 30 Hz... for the sake of most, if not nearly all buildings and fixtures out there. It's a potential liability issue that is my concern.

With subs, it's pretty much:

* Loud
* Low
* Small
* Cheap

Pick any two.

Cheap? Only if you undervalue your shop time!

Shocked
Cool

Just under 8 total hours per box. And remember, at VA shop labor rates, that's a LOT lower $$ than the SF Bay area.. Sad  
I DO confess a LOT of hours went into making it manufacturable, though..  Very Happy  The first article took well over 15 hours to walk through the assembly process (ever try building when the instructions haven't been invented yet? Twisted Evil ), implement acceptable grilles, as well as damping, testing, etc. Actually pretty low time for a first article, IMO.  Cool I'm not a newcomer to box building, either (started diddling with this as a kid in 1970).. but this is decidedly the most elaborate front loaded box I've ever come up with.
I will post the results - with the cost scoreboard.. once I get the first 2 completely out of the gate..
