Well, Adam, if a mere 20Hz isn't sufficient to give that monster a workout maybe the simplest thing to try would be the 16Hz warble tone on the Hsu site . Of course it's been rumored that the Hsu test tones will instantly destroy SVS subs, so you might also look at the RealTrap test tones. Then obviously you need a good Bach Toccata and Fugue in D Minor for an organ workout so that you can see if it's "musical".

Enjoy the music, not the equipment.
