Here's a place to ask about the basics. Some examples of "basic" questions: - What does roll-off mean? - How do you wire up a subwoofer? - What does bi-amping mean? In the spirit of self-driven learning though, please try to do some due diligence first (i.e. Google and Wikipedia) to see if you can't figure it out on your own. When you happen upon a great explanation or definition to something you consider "basic", come and share with others here.
