Andy2, glad to see that more people are getting familiar with options to have linear phase. The steepness of the slope had an impact on the pre ringing, as has the frequency of the filter. As the goal is to keep the pre ringing inaudible, lower order XO are better, especially for the bass to mid XO. For the mid to tweet xo, the frequency range of the drivers and distortion may determine the preference for the XO order. As the timing can be measured and adjusted for each driver separately, the time coherence can be obtained at the listeners position easily. 

Ok I tested polarity and everything is ok. 
Is it normal, even at say high 80’s dbs for the woofer to be barely moving?

Put your preamp in mono if you can.  Even if you can't, both woofers should be moving about the same amount.

You can use the battery to gauge woofer movement. Are both channels moving similarly with the 6 volt signal?

They are both moving a similar amount, about 1/16”
