The total length of the port should be 1.875" from edge to edge. If your baffle is 1.5", then I'd probably glue another 0.375" thick panel in the area that the port will be and drill a 2" hole through it. Maybe use a 2.5" x 2.5" square that's 0.375" thick or something like that. The hole drilled through the baffle and the extra piece will give you an overall port length of 1.875".
