Next job is to source crossover components and binding posts, I've made a cutting plan for the cabinets to come from 2 sheets of 18mm MDF with enough left over to make two braces per cabinet and the extra pieces for the baffle to allow the drivers to be flush mounted.
The sides and top will be veneered in Khaya wood (from the mahogany family I think but not quite as red as many of that family are). Front and rear will be a complementary paint finish that I haven't quite decided upon yet.
Should have time to get the MDF collected next week and start cutting and constructing the following week.
