FWIW, I use IsoAcoustics Mini Pucks under my NX Studio Monitors. This with a more conventional 24" stand, not a subwoofer. They end up being a bit more costly as one needs six under each monitor. My monitors weigh in around 32-33 lbs. So with a 6 lb. weight limit, 6 are required under each speaker. I ended up buying two 8 packs to the tune of $200. So 4 pucks are left over in my case. For those who have built a more complex cabinet or xover, maybe the extras would come in handy.
