In this box are 8 of these speakers, it have 8x the Vb like for the box below for 1 speaker, port tuning is the same. The Graphs are showing that it sounds / works similar than the box for 1 speaker, just it is much louder. The port have larger area than minimum recomended to reduce the port wind - this cancels the port noise. This box fits in even in a bigger car too.

I designed this box to compare it to the vented box. On all boxes Xmax is not exceeded above Fbs. At Graphs is a comparison between a vented, low-tuned rear chamber, and a low-tuned front chamber bandpass box. As you can see, only benefit is that in the bandpass boxes speaker can play a few Hz lower cleanly at full power, in other aspects the vented is better. Btw, on 3D and on Drawings you can see the low-tuned front chamber bandpass - pretty plausible to build (acceptable outer dimensions and port szies).

In my opinion this woofer in this box will sound really accurate and deep, but it will be not so loud (amp. resp., and SPL graph). The Xmax is not exceeded at higher frequencies than 26 Hz, so this is the lowest note what it can reproduce at it's full power cleanly - deepness. Phase response graph: at Fb (35 Hz) is almost zero grade, and at every "subwoofer frequency" the group delay is like 1/3, 1/4, or 1/5 the time compared to the time of the actual frequency - reasons why it will sound really accurate.
