Weighting down Vandy 2wq's?

After owning two 2wq's for a few years, I felt they had more to offer in impact and tautness than I was realizing from my system. I hit upon the idea of mass loading the top of each sub. A quick trip to Walmart and $78 later, I had placed one 45 lb. weight lifting disc on each cabinet. The bass is deeper and tighter than ever before. The impact of each deep bass note is so much greater, giving drive to music containing deep bass content. Symphonic works benefit spacially with the soundspace benefitting from the reproduction of deep atmospheric bass. The soundspace is larger and more palpable.

I highly recommend this tweak to any and all 2wq owners. This would probably benefit other brands of subs. as well.
