Believe you me. Start with a proper eval of your room by a specialist. Best 500 you will ever spend. ANYWAY you will need to do that if you want the smallest chance to integrate your subs. 1) Room measurements 2) Apply treatment 3) Add subs - yes, 2, not 1 I have Magicos. Subs are game changer. I learned that a while ago. I have two JL Audio S/510.

I was going to buy from and have installed by the folks that are setting up the Wilson's.  That is why I posted prior to speaker installation.

I want to feed the subs setting the lower crossover point, but I don't intend on having the Wilson's fed by the subs upper crossover.  I would think that this would cause a bit of a peak at the lower end served by the Wilsons and the subs.

The Sabrina X has very solid bass Thst is pretty close to full range.

my brother had them in his Big room with 2 JL Audio  Fathom 12 with built in room correction. He sold them this past year for the Shasha Daw to full his very large room , but the Sabrina X lacked very little ,in most rooms allthe speaker you would need without subs IMO.

Don’t buy the JL E112s. I have two and both have broken a number of times. Using their internal highpass crossover adds a lot of electrical noise to the system (buzz/hum).  I will replace mine with a different brand sooner than later. 
 

Running subs under your speakers without a highpass crossover will make your system worse. the timing will never be right. 
 

Running subs with a proper highpass will take them to a new level. The JL CR-1 would do the trick. Add any quality sub at that point. 
 

based on the measurements the Sabrina needs subs unless you are placing them less than 3’ from the front wall based of the -10db point and room gain.
