I want to make a 410 enclosure in woodworking class in school. Just so I can learn how they work, and get school credit and their tools to do it. I've read cabinet building 101, and majority of the other links, but they are all really confusing and not as helpful, most of them are 2 speaker enclosures and people were throwing numbers out. From what I have learnt... I need to determine the goal litre ammount of my box. I need to determine which speakers will be the best to buy. I need to determine how big my ports are going to be. I'm thinking that if possible, I can make it something simular to a genz benz x2? Weight and size isn't a problem here, it's the learning experience I want to gain. My shop teacher has the right wood, and I have a little idea from other cabs I have. Will I need to isolate the speakers into different parts of the cab? Should I also have a horn? I wont need to know how the wiring goes until a few months, but I do need to know what to do to get started with the wood. Should the cabinet be air-tight other than the ports? Even around the handles and such? Any help is appreciated, and sorry to creat another post about this, I just didn't want to hijack someone elses, and couldn't get much information out of other posts such as "cabinet building 101"
