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!

Thanks so much for all the great advice! 

I forgot to mention that I am driving them with a McIntosh MA8950. 

Thanks audioman!

Unfortunately, my budget is exhausted after the McIntosh and Sabrina's so the subs are a carryover from my prior system. The remaining $$$ is for proper cables. Frankly, the way the room acoustics are optimized when the Wilson dealer was setting the Sabrina's up they were tricked into thinking the subs were on when they weren't. 

This is all very helpful information. I will definitely take measurements in the room but leaning toward not using subs at all now. I’ve felt that the bass has decreased the quality of the sound which is likely a reflection of both integration and how good the SabrinaX are. 

I read more on using ARC Genesis. It is highly regarded, at least from TheAbsoluteSound.

Definitely important points, I have a fully treated ideally shaped room and they were installed by the owner of the Wilson dealer. I marked their original positions in the room and made some subtle, perhaps 2 inch, changes. They are definitely in the zone of neutrality, positioned about 2.5 feet off the front wall, 5 feet from the side walls, and listening position is about 3 feet from the rear wall.

I took measurements based on advice above and also ran ARC Genesis. I currently have them crossed at 45Hz and it is sounding really good. Next step is a final decision on cables. I’m borrowing AQ Robin Hood Zero’s. I hope to audition some others from the dealer before making a decision. I read that Transparent is what Wilson has used in the past a lot.

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. 

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. 

For anyone who stumbles on this thread down the road, I crossed at 45Hz and paired with Transparent Audio-Super speaker cables. I tried Robin Hood Zero, Nordost Heimdall as well. The Transparent were the clear winners to my ear and like others have said, a sonic match for Wilson speakers. I felt the Robin Hood was a bit dry and the Nordost were very much too bright.
