I think I will be going with the SVS Plus. They are now $300 cheaper shipping included. Last year they were almost$400 more expensive.

I perfer an unsealed sub for movies anyways. Sealed I like for music, however, if I decide to upgrade someday to the M100 I won't need a sub for music and the Anthem has that option for music playing to cut out the LFE.
