Hi,
Please help me choose between below 2 systems
1) A well braced sealed subwoofer with 15" driver and driven by 600watts RMS amp
2) A well braced push pull dual 12" driver, each driven by 300watt RMS(ie 300wx2), the drivers are mounted on opposite side of the enclosure for mechanical force cancellation.
If we ignore other differences like xmax, surface area etc then how much difference does force cancellation of 2) make if 1) is well braced?
Thanks in advance,

Honestly there is not much difference at the power you list. The force cancelation is only beneficial if you really need it.
First priority, meaning the aspect that causes the most audible impact, of any loudspeaker system by about a mile is frequency response. Which is determined by the speaker (TSP), enclosure, and filters (passive circuit, or active / digital via DSP). You'll also need a measurement system to verify your frequency response.
Resonances and eliminating them would probably be the next relevant point.
Ensuring perfect sealing is also very important.
Once that is solved to a satisfactory degree, you can worry about such things as nonlinear distortion.
After that and everything else, then you can worry about bracing, which has never been proven to impact the far field (= @ listening position) response of a speaker to a meaningful degree (all pertinent comparisons have been performed either via near field or motion detector measurements, which don't allow any conclusions on the far field impact).
