Its crazy. When I turn on the system, I see the speakers move but the volume is being reduced :P
Im not worried about the sounds below 20 Hz since the most dB's come from 100 to 200 Hz.
What's the primary range of frequencies you're cancelling out? I think you'd be better off exploring using multiple speaker (even smaller drivers 5", 5-1/4", etc) than trying to find and use oval speakers. You can find waaay more options in round drivers, better built, better quality. Are you installing the drivers in speaker cabinets or just using them in free air? Speaker cabinets would allow for some interesting tuning options that would extend the range of frequencies of course.
