I hope that this is the right place for this as I am new here. I am embarking on a La Scala DIY build. I have been through everything relevant I can find (I think) as to constructing these, but I still have a couple of questions. I am going to go with the Crites 15" woofer and I have found the dimensional changes needed to accommodate it without cutting the woofer. I am going to use 3/4" Cherry plywood veneer as you cannot find 1" anywhere I live (Spokane, WA). Will probably get the braces I have seen for sale. It looks like the hole in the floor of the doghouse is there for access to the woofer, if needed. My questions are: 1. Is the doghouse removeable from the cabinet itself to gain access to the woofer or am I missing something? 2. The majority of plans indicate that the woofer is attached with T-Nuts to the motorboard, yet some pictures I have seen show it mounted to a separate board, or even to a round ring that stands off from the motorboard. Is that just personal preference? 3. Where do you actually obtain the midrange and tweeter horns? There is a lot of discussion about what people have used, but little on where you purchase them. I found the site that sells the various crossover networks. I really appreciate any information. Thanks in advance.
