Just a question out of curiousity. Some speaker designs are sealed & others are ported. Now granted, the designer had specific goals in mind for their performance by choising one of the two designs. What is the real difference between the two? Does a ported speaker provide more bass than a sealed speaker? Does one design perform better than the other, & if you were to stuff the port holes how would it effect the speakers performance? Could that possible harm the speaker? I think it's all about moving air inside the cabinet. In a sealed design where does the air go or maybe it doesn't. I guess either design has it's +/-. Any thoughts?
