SabrinaX Sub-Crossover

First time posting. I recently got a new pair of SabrinaX speakers and paired them with two Martin Logan 1100x subs. The system together sounds incredible. The SabrinaX is rated down to 31Hz. Where should I cross-over the subs? I did it at 35Hz with a steep roll-off (4th order) but wondering if people with more knowledge have any recommendations? 

Thanks!

60hz with a highpass is a good starting point. Basses on the stereophile measurements of the Sabrina X, the woofer is taking a dive at 70hz. There is zero chance an 8” driver will outperform subs at 60hz-70hz.

Well placement of the speakers will be more flexible with subs. The farther the speaker is from the back wall the lower in frequency it will cancel. So once using subs you can walk the speaker out father from the front wall with no negative impact on the bass, Food for thought
