I don't have the SVS. I have a 145 Liter sealed 15" Tempest. In music it sure is nice to have a sub that is not boomy. On the Tempest the hand bass sounds like it should. The general consesus is that a sealed sub will generally give better music performance; while a ported sub will give you the lower slam for home theatre.
But I'm sure there are arguments against this generalization.
But if you like good clean bass in music choose your sub carefully.
