I don't know how many of ye would have seen it but anyway. I am trying to design my own box for my tempest (kind of as part of college project), i read somewhere before of the dimension ratios that can be used that will reduce standing waves in the box. It was something like (1)W*(1.2)D*(1.5)H .If any of ye have seen it before could you please let me know of the ratios or even better the link to the site. Cheers One other question, any of ye ever use ALGORE software before. I am going to try to do a FEA (finite element analysis)of a port to see how much of a difference it does make to air flow. Just wondering how hard is it to use, starting off and learning how to use it by yourself.
