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!

Funny I had too much bass with my Sabrinas when I upgraded from Pass XA30.8  to Pass X260.8 monoblocks and was using Acoustic Zen Absolute Copper XLRs. No sub(s).
Balanced it out by upgrading to Nordost Tyr 2 XLRs. Opened up the top end, cleaned up the mids and tightened up the bass, plus better clarity.
But my room is probably smaller.

15ft x 13ft with 10ft ceilings. Large plush rug, GIK acoustic panels with Guilford of Maine acoustic fabric. Blinds on windows are down and made of wood, other decorative art on walls is dense fabric. Soon will have vinyl and CD’s etc on a wall shelving system that should soak up the early reflections from one speaker.

FYI, tested AQ Robin Hood Zero which sounded fantastic. Then just tried Nordost Heimdall 2 which also sounds fantastic but I cannot audibly tell a difference. For reference, I took some AQ bare wire 14awg and in excellent condition, and it sounded muddy and lacked detail. I know nothing about cables but it was pretty obvious. Wish I could try the transparent. I’m tempted to roll the dice for the Super or Plus cable given they supply Wilson.

 

I am absolutely blown away by how good the SabrinaX is. 

@upstateaudiophile yes the Sabrinas are revealing and benefit from top notch cables. I like the Audience AU24SX speaker cables in my system. If you can locate a used set, I wouldn’t hesitate to recommend them. Great value. 

I realize this thread has evolved into “help me make my system awesome” so last question. Do I go with Transparent Audio Plus or Super cables? It’s 2200$ for Super and 1100$ for plus. 
 

thank you all again.
