    Perhaps possible to get 98 dB sensitivty with a real 28 Hz to 17 kHz range (flat) using affordable speakers. It would be a 200 or so litter box though with two 6" ports me thinks.

    The GW-1258 is super cheap and seems to do OK with low frequencies. But it lacks xmax. The Eminence Kappalite 3015LF-4 maybe the one to get, but it's pretty pricey. We'll see.

    Not sure yet. I can. But not sure where to put a pair of 200 litter animals.

    I'll cook a few things up and start a thread. Just for interest and pass the time. I feel for home use a 12" GW-1258 will likely not run out of xmax (2 mm). But a true PA application will probably benefit from the 15" Kappalite with its 10 mm xmax. For high output sub-bass, it's not just cone diameter, but xmax as well.

    200L? that's like 7 cu ft. That's like a single enclosure for BWC club.

    Yup. Recommended volume for Kappalite w 38 Hz F3 is 180 liters. This is true 38 Hz crazy bass. A speaker that may have the power to do some structural damage. I mean 123 dB SPL at that frequency is pretty brutal.

    I don't get compression drivers that well though. Some can do about 111 or moer SPL. But even 18" Pro subs rarely go about 101. You would need like 3 18" to match that, and that's not counting baffle step.

    That Vifa/Peerless semihorn silk tweet I noted above can do 99 and one may still need to tone it down a little for the 15" Pro Kappalite.

    LOL! I think the Kappalite even has a heat sink!

    I know you mean 200 Liter but it made me laugh to think of a 200 litter box - my god man, that is one damn big cat.
