On the Ultras is it best to recess the woofer and tweeter on the front baffle? I have a Jasper circle jig for my router so the woofer recess is not a big deal the Vifa with its squared corners would be a little more difficult. I would like to do what's best, so if recessing the drivers is going to yield better sonics then I will give it a try. I also thought about making a front trim ring for the Vifa and recess it into that and then mount that to the front baffle. That way if I mess up the recess I can just fashion a new trim ring rather than scrapping the whole baffle. Any thoughts or help would be appreciated. I have all my parts to build the Ultras. Hope to start after Christmas.
