Since I probably don't have enough sub listening experience to pick out minor differences, I just wonder if the port noise is going to be an issue. Is it only noticeable at extreme volumes, or is it also noticeable at loud volumes? I know those words are subjective, but I'm wondering if I'm going to hear it every time the sub is putting out a loud bump, or if it is only under the most extreme circumstances.
Also, a lot of reviewers say that the VTF-3 is a very "musical" sub. I haven't heard anyone say that about the LFM-1 EX. Would that comment carry over to the LFM-1 EX, since they are using the same driver, and (I assume) the same amp? I'd like something that also sounds good for music, but movies are really the focus for me.
