Why do these softwares give different values for these. In bassboxpro I have box fill set to none and I modelled my box in both programs with the same ports/volumes/power but both gave different results.
Online port length calculators agree more with winisd, and on a previous box I designed (tuned to 25.5hz) I actually found the tuning frequency by using test tones and checking excursion. The box was designed with winISD and the tuning frequency was correct. I find it hard to believe that the freeware and online calculators get more accurate results than a paid software.
Anyone know why these softwares give different port lengths and port velocities?
