Box Plans Please

[ds80mx 10+ year member]

I need a ported box designed for a type R please. (I know you people hate them). I really dont understand how to use WinISD.

The max size i can go is 17x15x21 (WxHxD).

I think the best tuning would be between 30 and 36hz.

I would design it myself but im not sure how to. Thanks for helping.

With a sub disp of .15cf ( not sure exactly what it is), the port length is 31.48944786, so i think your pretty close //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
