For years I've been using a Vel DD-15 with modified VSM-MX and BBAM. The sub works well with crossover at 30hz and steep 24db roll-off. The effects are subtle, adding just the last measure of LF embellishment-- quality not quantity.
I believe the more recent Velodyne software revs don't allow crossover to be set below 40hz. IMO this precludes their use with VSM.
