Hello fellas, I'm in a bit of a conundrum. I will be upgrading my receiver in the near future, it will be a Yamaha with YPAO. However, I will be upgrading my sub to a HSU VTF-3 before then. My question to you all is will I still need to eq my sub with my BFD or will the YPAO take care of it? My thinking is that I will still need the BFD for true accuracy.. Thanks gang!
