This is an outstanding app, Stillwater designs (Kicker)has been making subs
forever excellent products and service. Now I ready and prepared to build
a box for my new 2 -Kicker Comp R DVC 10's 4 ohm. But the only thing I've
noticed with the app is it shows my 2 subs rated combined 1200 watts input
required when it should be 800 watts but, Im going to set my amp at 4 ohms
938 watts should be good.....anyway Thanks again for your awesome products.

A good layman's terms box builder. Yes it's quirky but if you pay attention between tabs you'll figure out what's going on. And the answer to the guy below... the port volume is included in the final rendering/cut-sheet, so you get to choose how & where you want it. If you can't figure out how to design that you probably shouldn't be building an enclosure to start.

Could let you do just a little more but so far so good all my boxes are having good results so far and the wiring options are definitely tight and understanding how to build is tight too

1. Custom Box opt miscalculates :(2. Only for one thickness mdf. You can't choose 22 or 25 mm. 3. Random miscalculations! 4. Useful to get specs on your Sub and port frq calc.

Doesn't have my kicker subwoofer (L7T). Ported box builder doesn't help you with port specifications at all, just tells you to make a box.

WTF? Downloaded this app in effort to help me design a custom box. The calculator is so up the pole it's not funny. I followed the instructions, only to have none of the dimensions that I entered show up in the final listing, and dimensions so small they're not humanly possible. And it would be really good if the dimensions that get calculated would actually come up with a scale drawing or a plan, so you know what dimensions go where. Improve it. This doesn't even deserve one star.

Doesn't even have Kicker's flagship square L7 subs in the box builder, and doesn't include the port/vent when building the materials list or show one in the exploded view. The two things I specifically needed....
