Actually this ported box is that box which maximises out this driver's output potential on official sub-bass range (20-60 Hz), becouse the driver in this box will have ideal power handling down to 20 Hz + it reaches but not passes over it's Xmax on it's RMS power at 20 Hz and higher than Fb / lower than 60 Hz. Also, 4 Ohm version of this driver will perform the same in this box.

This is a windy L-ported box for this woofer for a car like mine (57Hz/12dB cabin gain including the trunk). I filled in / let SBL to count out the missing speaker parameters to be able to do correct simulations with the complex computation model too / single voicecoil. So, I optimised it to match those needs and rules what I wrote down many times in my previous shared projects, but now it is true for both computation models, not just for the simple model.

This box I've optimised to pull out the max-sound of this driver on official sub bass range (20-60Hz) + be the loudest in a car at 20ish frequencies (to be windy): F3high=60Hz, reaching / not overpassing Xmax at 20Hz + between Fbs. The result is a 16+dB peak around 24-25 Hz with the stock 55Hz/12dB cabin gain. Also I've used huge port areas to not overpass 10ms air velocity to cancel port noise. I've used complex model - these aspects are OK with switched off behaviours too (Xmax is not reached between FBs)
