SabrinaX Sub-Crossover

@upstateaudiophile My Wilson Duette are spec’d to play to 36Hz. I think my in-room response is better than that. I’m running dual SVS SB-16 Ultra subs. The way I have them dialed in is such that they do not draw attention to themselves. I have not gotten into measuring the room yet. I have a UMIK microphone and will do that. The thing is, when I turn the subs all the way down via the SVS app, I’m still very, very happy. In fact, on more than one occasion I forgot to put the subs back to their integrated setting. The Duette use an 8" driver I suspect is very similar to what is in the SabrinaX and they are really something for a stand mount 2-way. On more than one occasion they have made me say "WOW!". Your speakers are spec’d at 31Hz... of course that depends on the room.

My point is this... don’t feel like you are "missing out" on something by not having subs with your SabrinaX. Ultimately, I guess it depends on what you listen to, and at what volume. Still, based on what I’m experiencing with my Duette, I could happily live with the SabrinaX - without subs or needing to invest a ton of money into better subs.  I guess you'll have to make up your mind about that.  Good luck and Have Fun. 

@upstateaudiophile you should definitely consider using ARC to tune your subs.  I would be talking to both Wilson and ML to get advice on the crossover parameters you are asking about.

Thanks again everyone, excellent advice for me to work with. 

In room measurements are the best way to integrate subs. The in room response of the Sabrina speakers is more complicated than the specified bass roll-off and subs can help correct it. I do not know if ARC/PBK is powerful enough for good measurement feedback or not. It certainly could be. With in room measurements setting the crossover point is easy with some experimentation, especially with speakers with decent LF extension, like the Sabrinas. 

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.
