Looks good, Chalugadp! I'll be interested to see how you glue up the curves.
Also, just a heads up, the width between the edge of the port holes and the edge of the baffle is only 3/4" so be careful about how far undersized you construct the box. Taking much more than 1/16" off the baffle edges could cause interference with the ports and the box sides, if that makes any sense. The good news is that the ports are slightly tapered so even if the box sides are pushed in a bit, the ports should still fit.
Take lots of pics along the way! 😃
