Well, this is the response I received from SVS.

Hi Rob,



Don’t bypass the SVS filter. Leave the SVS filter(s) at 20hz, and use the 15hz setting for the Velodyne EQ. Having cascading subsonic filters shouldn’t make an audible difference in this context---the SVS filter will be rolling off the signal very rapidly(steep) by 15hz anyway.
