    I need help designing boxes for a couple Dayton DVC 15"!
    -I really need them in separate boxes to fit nicely below my screen where I now have my old 15"ers. Later I will be building a Center channel low frequency box that will hold (1) Dayton 10" that will need to fit between the two 15" subs.
    -I would like to have it tuned as low Hz as I can get.
    -Front fire
    -Ported I think?
    -Cannot be any taller than 18"x 36" wide, depth no limits with in reason.
    Please help me out I'm not too good with the computer building programs!

    Wes,
    I see another deal of the day buyer [​IMG]. I have exactly the same situation. I used winISP and came up with two designs for a single driver, ported.
    8.83 cuft 20hz tunning and F3 of 21hz
    10.95 cuft 20 tunning and F3 of 19.3hz
    Hopefully some of the guru's can chime in. And guide our ways.

    James those are two of the more popular sized box's for the DVC drivers. You can see the one I build on my page along with the response plot.

    James, So is this sealed or ported, and if ported what size of ports?

    Could you help with the box measurements?

    I would tune it lower....maybe around 16-18 Hz. It would probably give a somewhat flatter in-room response. It would also give the driver more protection from overexcursion down low.

    Andrew,
    I checked out your page right when I bought them. I remember a post where you bought one of the PE DVC's. Very nice.
    Wes,
    Yes both cabinets are ported. I would be happy to help in anyway I can. Email me at jmudler@itcdeltacom.com . I will be off email this weekend [​IMG].
    Pete,
    I ran 16 and 18hz and it does not look as good? 16hz tunning freq increased the F3 by 7db (19hz to 26hz). 18hz tunning freq looks better but sightly lower output until the tunning freq. Oddly the F3 is the same for 18hz or 20hz tunning freq? Your help is appreciated.
    OT
    What kind of dust collection are you using in your shop? I remember a post with that saw from hell you have [​IMG]. Next purchase is a DC for my garage shop.

    I picked up the DVC 15 as well. Using WinISD, 10cuft and 18hz tuning looks very similar to Jack G's recommendation of 120l and 18hz tuning for the DVC 12.

    Tuning lower will decrease group delay, help protect the driver a bit more, and probably sound better, overall. It would mimic a low Q sealed rolloff. Room gain will make up for the rest, usually, and would probably be flat below 20 Hz.
