    Good Lord!!!! That is killer! I wonder if those drivers are proprietary or if they buy them "off the shelf"? Have you ever seen anything larger?
     
  3. What does it play like? ive not liked 15's ive played, so that probably wouldnt be my cuppa tea, love the attack of my tens :)
     
  4. It seems to me that these huge drivers have a place in a movie theatre, not on a stage.

    Not in a cab, but I have spotted that Fostex sell a raw driver (the FW800N) which is 31.5 inches. Though with such a small wattage rating and low x-max, I doubt it would be any good for pro sound applications.

    Cabs like the Whappo Grande aren't intended to be used by themselves, they are dedicated subs designed to carry the extreme low end of biamp setup. Unless you play extended range basses that go below a low B you probably would have no use for them.

    There are some people on this site that use them though, I belive Jean, the dude with the kick a$$ scary 11 string has one.

    Doesn't Al use Madison Hydras with 21s?
     
  8. Sure does.
     
  9. The Beyma SL2150 is an off-the-shelf driver. It looks very close to the specs revealed about the Accugroove. The Beyma wants a 10.5 to 15 cubic foot cabinet, and provides an F3 down to 29 Hz in QB3 tuning (15.2 cubic feet).

    This is a big boy, and not terribly practical for portable rigs. You can stuff it into a smaller cabinet, but this results in a mid-bass hump and steep rolloff below the hump. Efficiency is fairly good, hence the large cabinet.
