Would this be a decent example of standing waves: "Say you throw a rock into a pond. You notice the waves rippling out from where you threw the rock. You then throw another rock further away from the first rock. These waves move towards the first rock's waves. At the point where one wave meets another is a "standing wave"?" Referring to a sub: At the point where the waves meet might there be an increase in the sound pressure level? If where the waves meet, can there be a decrease in sound pressure level? Can a tube enclosure have standing waves inside it? The reason I bring this up is because of my dual SVS 25-31's. There is one spot in my 4500CF room where the bass is so loud it makes me dizzy but any where else and it's normal. That area is in a corner, yet anywhere else in the large "L" shaped room it's perfectly fine. Thanks!
