It does seem odd dimensions at first glance, but they're really not so weird - I just wrote them in decimals and rounded to the hundredths. If Жека will be routing flush, he'll likely add 0.1" anyway. That way it won't have to be tapped in or pried out.
But said in fractional inches, the dimensions are 11-5/8" wide x 6-9/16" tall and 1/4" thick.
I wanted to make the baffle cutout an exact match for the old H290 horn so the H290C would be a bolt-on upgrade for existing speaker owners. The H290C fits right in the same router groove, so flush mounted speakers won't have to be rebuilt. No change to bolt-pattern either. The baffle cutout has to be made slightly larger, because for performance reasons, the H290C requires a 10.5" x 5" baffle cutout. But that can be accomplished with just a few strokes of a four-in-hand, rasp or file. It fits right in.
