Descripción
The Vb and the Fb of this box is the same like DD's "full size ported box" for this speaker. The area of the port is much more bigger than DD recomends for this box - this bigger/longer port's displacement is the reason why this box is "big", but this gives an extra "boom" and reduces the port wind. If I count out: DD's recomended port area divided by this port's height (internal height of the box), this gives an 49-50mm port width. This port at this box is a bit over 50 % wider than recomended - 76mm wide.

I have a very old 24 l ported box for a 10 inch speaker, and I have an 300 WRMS/4 Ohms amp. This is the reason for choosing this speaker. The Vb after installig the speaker will be 21.71 l. See the graphs: unhidden port - green lines, and hidden port - red lines. I put in the missing speaker parameters manually to simulate the cone displacement + I find: Xmax=10mm, Xmech=64mm 2-way, so 32mm 1-way, so Xmax is exceeded on both versions, with uncovered port is bigger, but it is less than Xmech.

This is a unique L-ported box tuned to 35 Hz for 2 of this speaker. The speakers and the port too is on front side of the box. The speakers are not overpassing their Xmax above 35 Hz, and not overpassing their Xmech (32 mm 1-way) below 35 Hz. An interesting thing is that inside the box the distance between the port part #0002 and the left side equals to the port width = 90 mm.
