Will I benefit from a subwoofer with 20Hz speakers?

My source is a minidsp shd studio with Dirac going into Denafrips Gaia DDC to Denafrips T+ DAC to McIntosh 601 Monoblocks to Cabasse Pacific 3 speakers. The speaker's published frequency response is 41-20,000Hz. I presume this is achieved in an anechoic chamber. In my room however, it goes down to 20Hz, at least according to the Dirac measurements. In fact, I needed to flatten the curve and  reduce by 5-20 DBs between 20-100Hz due to the room effect.

So, considering I already go down to 20Hz, is there anything else 1 or 2 subwoofers will do for my system?  Would it create a more consistent low frequency field? I see many people adding up to 6 subs, so I wonder what I'm missing. 

Thank you for your insight!

We might be able to help you but first you have to tell us what problem you are trying to fix. What are you missing?  What’s bordering you?  Do you have enough bass?  Help us help you. I hope I don’t come out as being brash. The subject is very deep and it would help telling us what your concerns are. Thanks.

Look up "swarm subs"

I just re-read that you have measurements and use miniDSP.

Generally speaking to my mind, room correction systems tend to be too bright.  If you have the ability to control the tilt downwards try that.

After you get there, a boost in the bass (below 100 Hz) of around 4 dB is a good thing. The problem is if you aren't flat to begin with. 

Of course, all room correction works best with room treatment.  Take a look at the room simulator, below and see if your measurements are coinciding, and then we can talk about potential fixes.

20Hz @ 0 db loss?

Nice looking speaker. 

You have a magic room. The speaker defies manufacturers reasonable/real world  low frequency claim? Hmm...

I took a look at the website. This one is over the top:
