Dear @zdw11 @cardani : I can see that both of you are running your main speakers/subs to listen MUSIC ( at least do not posted for HT. ).
Now in the Ohm speakers the sub is part of the speaker ( I don't know forsure all the subs controls to operation. ).
If we want to listen in specific MUSIC through our room/system and want to add subwoofers the rigth way to do it is that those pair of true self powered subwoofers crossover ( should be. ) around 80hz-90hz but this crossover frequency is not only for the low-pass subs but we need and should be that the main speakers been too crossing around that frequency with the high-pass filter and in this waythat room/system will takes a true advantages to add subs to listen MUSIC because in that way the main speakers will be handling frequencies from 80-90hz and up and the IMD and THD distortion levels that existed in those passive speakers goes really lower in benefit of higher sound reproduction quality level and at the same time that room/system will handled with accuracy the low bass range and even can goes lower in that range.
Due that I don't know of the overall Ohm speaker operation then I could be wrong with but with the other gentleman that's the rigth way to integrates subwoofers to MUSIC soun reproduction as our main system use.
Here a link about:

Of course that one thing is what " should be " and the other what we like/want so in this specific subject everything is up to you and this post is only an opinion and nothing more.
