I was speaking with Brent the other day about the differences between the 350 and 500. I hate trying to quote these kinds of details without really knowing what I am talking about. This may NOT be acurate. Both the 350 and 500 use the same driver and same enclosure. Both have the same specs and both go to the same depth. The 350 will not be level as it drops below a certain point and will lose impact. The 500 stays level as it drops and keeps that impact. Also the DSP will keep it clear with no distortion. This will be most noticeable at louder volumes. Plus the 500 has more power and can play much louder anyway. He also says that the 350 is a great sub.

Some of you must play your systems pretty loud with all of these subs!
