Hi Brandon,
I currently am high passing my nx-studios and am messing around with the crossover point. I accidentally undervalued what I needed so right now they're crossing a little over 100hz to my stereo subs. I'll be adjusting that down to hopefully cross at 75 or so. In my small room the studios play to about 40-50hz when left full range even though specs say they only play to 70. Hope that helps!
