I am interested in a new sub. The one I purchased just does not seem to give me the punch that I am looking for. I am also looking for something on the smaller side. That is why I had to rule out SVS. Aaah! I really wanted a pair of those. Anyway I am really leaning toward Sunfire, but someone brought Earthquake to my attention. They said that the sizes are pretty small and alot of output. Anyone here have any experience with Earthquake? Thanks.
