    The home theater market sees subwoofers growing smaller and smaller, but in the professional market things are quite different. To perfectly illustrate this, Cerwin Vega has announced that it is introducing a new 21-inch subwoofer to its professional line. OK, the cat's out of the bag - this is a sound reinforcement subwoofer, and not intended for home theater use - but WOW, 21 inches - that's pretty big!


    To date, anything over 18-inches has been impractical due to issues with cone stiffness and breakup. A 21-inch subwoofer is a challenge and it seems Cerwin Vega! has broken through some of the limitations and made a product that can work well for professional sound reinforcement use.

    'sound reinforcement' translates to 'will vibrate shit'

    2k is seriously decent for that.
    I expected to see close to double that much.

    I was trying to find a link for an old Janis subwoofer that was somewhere near 25 inches or more, if I recall.

    And I came across this insanity. A 60" subwoofer, capable
    of 6" peak to peak, with an sd equal to 160 10" woofers,
    and 180db output.

    Do you remember the make and model of it? I would love to build some
    sub cabinets with drivers like that, only mount them in the basement and just run the ports in through the floor.
    The vas of something like that would probably be a hundred cubic feet.
    But with cabinets in the basement, it wouldn't take up any living room space, and it would still crush.:naughty:

    It's just going to shake the floor. Skip the ports.

    I was curious, so I looked for the Clarion 32" and I found the spec sheet for it.

    The vas is 100 cubic feet.:rofl:

    only rated at 1kw? wow, i thought it took more. but then again, it was built at a time when .25 ohm AB amps were used for subs. not 1 ohm class Ds.

    I was surprised to see that the xmax is under an inch.
    That plus it only has an f3 of 29hz in a 28 cubic feet vented cabinet.

    I'd hate to see the size of box needed for 20hz.

    I'd run it through some box design software, but I don't have any running right now,
    and I'm too lazy to install it.

    WinISD wouldn't let me load all the specs to save it as a file and design a box.

    I forgot to check back here.

    Yeah, winisd like the other guys said.

    I use the beta one.

    I also use passive design calculator .03 for crossovers.
