Is this how a Subwoofer Crossover is supposed to work?

I bought two Starke SW12 subwoofers that I installed.  So far I'm not particularly happy with them.  They are way too loud even with the volume set almost to off.  More importantly, I'm having trouble integrating them into my system and I'm wondering if that is because their crossover setting is really functioning as I understand a crossover should. Attached please find measurements from Room Equalization Wizard with SPL graphs of the two subs (no speakers) taken at my listening position with the crossover set at 50 Hz, 90 Hz, and 130 Hz. Ignore the peaks and dips which I assume are due to room nodes.  All of those settings appear to actually have the same crossover point of 50 Hz. All that changes is the slope of the rolloff in sound levels. This isn't how I thought a properly designed crossover was supposed to work.  I thought the frequency the levels would start to roll off would change, i.e. flat to 50 hz then a sharp drop, flat to 90 hz then a sharp drop, etc. etc..  But Starke says this is how a subwoofer crossover is supposed to work.

Any experts on here with an opinion about this?  Is it possible to buy an inexpensive active crossover that I could use in place of what is built into these subs?

I’ve spent the last several weeks attempting to integrate 3 separate subwoofers into my listen room along with my Moab speakers. From what I understand, an external crossover unit like the JL Audio CR-1 is essential to getting accurate time alignment between subs and main speakers. This essentially is a two system where everything above 90hz, for example, goes to the main speakers, and everything below 90hz is handled exclusively by sub(s). I don’t have such a unit and simply used several practical techniques to blend subs as well I could with my Moabs. If I can add anything to this thread it’s that integrating multiple subs can be extremely beneficial. And yes adding subs with the Moab has dramatically improved my low frequency room response, bass depth, sharpness and overall system accuracy. All the best. 

Happy New Year to all.
