I made this project for the same aspects, for the same purpose, in the same way like this project: https://speakerboxlite.com/project-info/24613/tab-info . The only difference is that here I used Vb, Fb and port area which gived BassBox 6 PRO for the same aspects I wrote in the project's description in the link I put here. Also I tried WinISD - it gived approx. 1/3 of Vb like SBL and BB6 boxes have, with slightly higher Fb = much higher F3 - I think WinISD's box is't good for these aspects.

This is just a base vented box design for this sub, good as a starting point for a more detailed final design using the Vb and Fb of this project, braces, etc... The Vb / Fb / port area is optimised to: Fb = F3, ideal RMS power handling at 20 Hz and up, 17 or less m/s vent air velocity, and maximising the output potential at 20 Hz and up (reaching but not overpassing X-max on RMS power).

This is just a basic closed box design for this sub which is good as a base for a final design using the Vb of this project. The Vb is the biggest possible net volume on which SBL's simulator shows ideal RMS power handling all way down to 10 Hz using both computation models, and also maximises the output potential - reaching but not overpassing X-max on RMS power.

This is a basic 2:1 bp4 box project for this sub, good as a base for a final design. The base was the Fb which SBL generated for the wideband bp4 box, and I just found Vbs in ideal 2:1 ratio which maximises the output potential (reaching but not overpassing X-max on RMS power), ideal power handling down to 10 Hz, and a port area which gives 17 or less m/s vent air velocity - all this using both computation models. Also imo group delay is kinda good for a more peaky box like this.

This is a base 2:1 Vb and 2:1 Fb parallel bp6 box for this sub which can be good as a base for a final design, just i am not 100 percent sure that that if it is good or not because imo it is way too big for this sub, but by the complex computuation model is good, but anyways... These Vb and Fb combinations are optimised: at 20 Hz and up- to maximise the output potential on RMS power (reaching but not overpassing X-max), - and have ideal power handling. The vent air velocities are questionable, but by the gr

This is a project for comparing the simulations of the 4 boxes I've designed for this sub - on the 3D is the closed box.

The Vb / Fb / port area I determined with BB6. This sub will be placed in an Audi A3 Sportback's trunk. The car's owner wants to have a box big like this (outer dimensions) + to sound good down to 20 Hz. So, I designed it to not pass over the X-max on WRMS up from 20 Hz + low Fb. This gives F3 = 30.6 Hz = it will be musical / flat in car (graphs). Because of SBL 3D designer, the sub will be flipped over in real: the front will be bottom - to have the sub be faced up and port be faced back to the trunk door.
