Hsu website says 1m ground plane measurement. Brent in S&V says he peformed CEA-2010A output measurement at 3m and added +9.5db to scale the measurement to 1m reporting standard mandated by CEA-2010.
Once you drop below $500, I don't think you will find a better quality sub than Hsu's lower offerings. They would be my pick if I had to limit my budget to under $500.
I feel the same way; I've tried some other sub $500 subs, and HSU makes a better sub IMO. If the OP can push his budget to $499, the SVS PB-1000 is definitely an upgrade.
