Guys that I know that have had both, and some guys on another forum say that the es18 is a lot easier to load and move around with a single person. They say that the dimensions are a lot less awkward. They also say that they outperform the ls801's getting a little louder, and going a little lower. The ls801's aren't really good sounding subs, however they do get loud as hell. I don't really consider 45hz to be sub bass.
