Best Tuning Port Calculator

I am trying to tune a 63.88 liter cab (10.5” x 16.5” x 22.5” internal size) to approximately 50-55hz for a Jensen 12” smooth speaker I have. I know that search results are useless, Omni calculator is garbage, and I don’t trust any of these YouTube videos to be honest...

What is the best calculator I can download to help me get the volume right for the port, and am I risking chuffing if I use multiple 2” ports or am I better with a 4” port? Or Slot?

I know you guys get posts like this all the time, but my searches are yielding links to old sites that seem to have gone to the ads. I’m happy to do the work, just point me to the best 2026 calculator and I’ll download.

Thank you!
