    80.5 Hz, LC, -15.0dB; 1/2 of LR24

  ST Left
     A -2.0dB
     Delay 2.18ms+1.31ms

  ST Right
    B -2.0dB
    Delay 2.56ms+1.02ms

All Polarities are NORMAL.

Both Subs fed through XLR 10dB attenuator.

N.B.  Cutting Subwoofer level is difficult; SVS's are high sensitivity compared with Behringer DCX which has high output, even with 10dB attenuator.  "gain pot straight up" is at least -3dB, which may be what is dialed in other side but not sure.  Experimental cut to SW Left will require adjusting SVS input level, fortunately it's a digital level control.  With level adjust, EQ 6 may go away.

Currently listening to my altMusic folder random shuffle through Sonos, taking a break from Pandora and William Orbit.  Beatles playing right now.
