3D model

The sub between a pair of Le Petit, to scale: the same 340 × 530 front, the same 22 mm OSB, the drivers firing sideways from the sides. Drag to turn, scroll or pinch to zoom, hover any part for its size. See-through, the two cuts and Exploded show the inside; Play bass moves both cones out together — the reason the box stands still.

Closed the finished box next to the pair: plain front, flush drivers in the sides
See-through the OSB turns translucent: drivers, tie strip, window brace and wool in place
Cut: front half off a section through the driver centres — the two magnets 38 mm either side of the tie strip
Cut: right half off the section from the side: tie strip at driver height, window brace 330 below the top, wool below
Exploded how the panels go together: plates over everything, sides between, top and bottom between those

The model uses the same dimensions as the building plan; the drivers are drawn from SB Acoustics' datasheet.
