You are correct again. Once I flipped the spider, the material naturally fell into place. Many, many thanks. The plan is to glue them up as 2234s sans dust cap, put them in a 4507 cabinet (5 cu. ft.) and test them before I decide to add the mass ring. I likely will add mass because they're going to work as subs for the 4612s. In essence, a B380 under them...biamped with electronic crossover.
