I am a car audio enthusiast making the way to home audio. I know car audio has it's limitations. I mention car audio only as reference to my question. We use the term "infinite baffle" for a woofer mounted in a car door. I believe "quasi-infinite baffle is a better term. A proper infinite baffle is a different thing altogether. What is "dipole" and how is it different than infinite baffle? Without getting too technical, what makes a driver good for a dipole configuration?
