I have watched this forum for several years and have decided to take a Leap Of Faith at building speakers. I have ordered a speaker building book online to help with the volume issues etc. In your opinion. 1. Two way two 8" drivers and a tweeter. 2. Two way one 10"-12" driver and a tweeter. 3. Three way one 10-12" driver 5" mid randge and tweeter. 4. Three way two 8"drivers, 5" midrange, and a tweeter. 5. Crossover networks from parts express. 6. Where to buy high end crossovers if not the Parts Express kind. 7. Should I build the crossover. I ask this as I cannot find these specific questions in history. Your help is greatly appreciated.
