I can say that i truly love my SVS sub BUT if you are looking to have dance parties at the house then maybe a different one is for you as I dont feel that my PD12-NSD is as good as it gets for music but yet is better than anything i have had. I think that maybe the SVS is more tuned for lower frequencies than heard is most music. This is all amateur opinion of course. For movies i cant imagine anything else in its price range really out performing it.
