I was wondering which, if any, auto-setup on new receivers included eq./set-up for under 100 hz. Does the Audyssey MultEqxt Room Eq. do this? or YPAO? or MCAAC? If not, what products are there out there to eq. the sub frequencies besides the Velodyne SMS-01, or what subs have a multi-channel eq feature besides the DD series of Velodyne and the JL Audios (I prefer a down-firing sub)?
