Regarding whether the dual voice coils would still be used the answer is "yes". The dual coils are not used to combine left and right channel information in the way that, say, the center channel of a Hsu Ventriloquist does. The dual coils are wired in parallel to provide a lower impedence (1.3 ohms, I think) which makes it easier to drive high power from the specially designed amplifier into the speaker.

All of the other comments about losing LFE information from the other channels should be considered seriously, unless you already have other sub(s) in your system handling those channels.
