Disabled man trying to figure out the correct ported box for 15” Ultimax subwoofer

[CajunLB]

Hello guys and thanks in advance for any help that you guys can give me. I have a 15 inch Dayton Ultimax subwoofer and the 3 foot Dayton audio sealed box .I have spent the last three hours trying to figure out a good size ported box for this driver. I’m using an Apple I pad mini 2 and most of the programs I’ve tried using say they are incompatible. I’m not sure what else to do but ask the experts on Audioholics for help. All that I really know is the box Will not be small. I would very much appreciate if some of you could model different sizes of ported “slotted or round “boxes for me between 6-10 cubic feet and tuned between 20-15 hertz and let me know the pro’s and con’s of each.
I have about 2400 sealed room and using the Dayton Audio 1200 watt DSP amplifier. I would really appreciate any and all advice.

These are Parts-Express suggestions and duct sizes for cabinets suited for the 15" DVC Ultramax subwoofer. Larger enclosure dimensions may be used. You may contact them on their website for guidance:

Cabinet recommendations:
• Sealed 3.1 cubic ft. (net internal) with 3 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment
• Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4" diameter by 26" long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.
Should you not use flared ports, you can tell them as that would change the length of the ducts to obtain the same fb (box tuning frequency).

Thanks @Verdinut . I read a few post on a few other threads saying 6 feet wasn’t quite big enough for under 20hrtz response. But that is good news because that’s; not anything close to the huge box that I thought I may need to build.
