Honestly with that much cone area I would! It is a night and day difference in SQ when tuning lower. I use to run my 5200 at 35hz but when I put the new box in with interchangeabe ports it allowed me to switch at will and I find myself using the 30hz only. If you like music, then I would tune at 30, you'll like it plus it seems to carry a further distance if that is what you want //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif .
