Default Dual voice coil for feedforward?

Yet another idea I have had that seems really obvious, but I cannot find any mention of it anywhere.

One of the problems of using feedforward error correction at high power levels is how to sum the signals efficiently. How about using the two voice coils of a DVC driver to sum them? With a high power, high efficiency amp for one VC, then a low power, low distortion amp sending just the error signal to the second VC.
