if you put an m/s system on each side of the stage, the results will not be much different from putting up any other pair in wide a/b in the same position, except that you can adjust the width of each mic system individually after recording * - but you won't get any steering option as the spaced fig8's are far too much apart: you need a great deal of coherence between capsules for steering the focus in any direction...

...or then an entire array of capsules to get some directivity towards the lf (which is however only possible to achieve at a given frequency and depends on distance between the capsules) - to find out more about this, you need to look into an entirely different area of our profession though and would need to check out the literature on arraying of subwoofers - what's true on the way out is also true on the way in.



* i do occasionally use a pair of tlm-170r's or oc-818's on each side of the stage (as near ambis) and can then adjust their width either via remote control before recording (in case of the neumann's) or then after recording (in case of the austrian audio's - of course this would also work with mk twins or any other dual capsule mic of with both capsules can get recorded)

placing the two mics Left and Right of the stage (performance area)
then steering the Y capsules, left and right respectively?
As stated in the manual.

Steering (C700S only)
The C700S provides another figure-8 signal from a side-facing microphone capsule called “Y” to allow the “X” figure-8 signal to be steered in any direction. If you add two figure-8 microphones together, the result is always still a figure-8 pattern, but pointing in a different direction. Remember that all the patterns derived with the W and X signals were facing along a front-back axis. Now consider what would happen if you were to rotate this axis. The Y signal is facing left, so patterns derived with all Y and varying amounts of W added will be about the same as the patterns derived with X and varying amounts of W – only now they point 90o to the left.
If we use a mixture of X and Y, the resulting pattern will be pointing anywhere from 90o left (all Y) to 45o left (equal proportions of X and Y) to straight in front (all X). If we continue around and invert the phase of the Y signal, it’s the same as having the Y capsule pointing right, so we can now derive all the patterns but pointing anywhere from 0o to 90o right. Continuing around, if we invert the phase of the X channel, the patterns are facing toward the left rear, and if we invert the phase of both the X and Y channels, the patterns face toward the right rear.
Summary of Steering
• Virtual direction of X may be changed by adding Y
• Any pattern created with W and X is therefore rotated by adding Y
+= X signal plus Y signal equals left-front facing figure-8

To recap, we can rotate the direction of the figure-8 signal by adding Y to X. The resulting pattern, regardless of the relative amounts of the two signals, will always be figure-8. We can call the summed X and Y signal “D.” The front lobe of the D signal will be pointing somewhere on a 360 degree circle according to the relative phase of the components:

Could this not give a beautiful, & broad capture of an event?
