In this project I simulated 3 boxes for this woofer which are acceptable in outer dimesions for me. Red: closed box: ideal RMS power handling down to 10 Hz, green: Fb=20Hz vented box with a unique Vb to have acceptable group delay down to 20 Hz, blue: unique Vb and Fb vented box to have: ideal RMS power handling and acceptable group delay down to 20 Hz, acceptable vent air velocity - result: more linear SPL at 60Hz/12dB cabin gain between 20 and 45 Hz compared to the 20 Hz box - this is on 3D.

This box I designed using WinISD and SBL hand-in-hand for 2 pieces of Tesla ARN 5604 woofers - home hifi woofer from '80s, parameters are re-measured after breaking in. My requirements were the same like in the most of my projects. I simulated this box with several popular 12 inch woofers - Vb / Fb is changed to have all dimensions the same - this DD woofer is OK in it in my opinion. The only thing is that it needs to make the port endings perfectly round to avoid port noise (high vent air velocity).
