Will Meridian make it possible to have a "True Mono" setup of two mis-matched subs? (You can only have a stereo pair of subs if both are either digital or analogue, if you have one of each you will get a front centre sub + one rear sub). I want one setting where the same sound info goes to both subs. (G68)

HD621, G98DH, G68ADV, Bc Acoustiqe ACT A3, 5200C DSP33, NuForce Reference 9 monoblocks, 2x SB3's, Velodyne DD-15 & DD-12 Subwoofers and a Meridian sub.
