    May be a solution...

    Have a look on this thread:

    Box for 2242H

    What you think about my calculations?
    16 Hz can not be substituted

    4645C port length

    Giskard,

    The 4645C seems to have a 8" port, according to my crude measurements from photos. It also has a straight port so, to meet your requirement of 4 to 6" clearance at the back, it can't be more than about 12" long. Is this consistent with tuning of 25 Hz?

    The 4641 seems to have an identical cabinet at a much lower price. See anything wrong with obtaining a 4641 and replacing the woofer with a 2245H without any cabinet (or port) changes?

    Thanks,

    John

    I finally received BBpro6 and am learning how to use it. What I am looking for is for a design that puts out high SPL.

    The 2242's are being used in a club that is approx. 4500 sq. ft.
    BBpro recommends a box tuning of 50+ hz and a relatively
    small box.

    Is this correct? What would be a good design for high spl?
    1 inch MDF is nowhere as cheap as 3/4 inch. So I don't want
    to keep spending money on trial boxes.

    See what a 4.0 cubic foot box tuned to 40 Hz with a high pass bump filter at 40 Hz (5234A/5235) looks like.

    4641 with a 2245H

    Giskard,

    Thanks for your input. If it works out really well, I may add another for a pair.

    Re: 4641 with a 2245H

    Oops, sorry John. I have 2242 on the brain. Anyway, when the 2245 was used in these enclosures it was tuned at 30 Hz instead of 25 Hz. Basically you'll end up with a "B460" without the high pass bump filter from the BX63. This isn't really a problem at all. Try it without the EQ and then add EQ at 25 Hz as desired/required. I wouldn't necessarily seek out a BX63, you can easily build your own high pass bump filter or modify a 5234A/5235 to do it for you. I've posted how to do that in some other thread somewhere. Anyway, you may find you don't need the EQ at all depending on how low you are going to cross over and how well the system integrates with your specific environment.
