Hello everyone, I am so way new here, I have spent some time looking over the posts on Home Theater Forum , and think I have worked up the nerve to ask some questions. First of all I think I would like to try my hand at building speakers. 1. I was wondering if a person can build high quality speaker that an audiophile (not that I can call myself that) would be proud to own for less money. Now when it comes to woodworking there is nothing I can't handle (Cabinet maker by trade) , but I am speaker design dumb. Which leads to my next question? 2. how do I figure how much space is needed inside for a speaker perform and sound it best? 3. I understand there is software, Does anyone know if they make any for Macintosh OS X ? 4. To a certain point I understand how a crossover network works But I don't understand how to put one together. How far does this set me back? Should I even worry? 5. Seal or ported What is better? I was thinking I would like to build a sub to start with . I know I can make it look great I need some help to make it sound great. I have a 18 X 18 room. that I want to fill with clean tight sound. Most of the use will be for movies and some music. I have a 8" JBL sub right now (please don't laugh) I don't feel like it can handle the level that I would care to push it to, it sounds like it wants to bottom out . I want to get away from that with out going over the top. I don't want to be reckless with my money for fear that I may not be a good speaker builder, not that I plan to fail. I just want to be wise with my cash. I hope these are the right questions to start with. If not please point me in that direction.
