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!

Sounding like a fan boy myself, @atmasphere ​​​​​@erik_squires  both have decades of experience and knowledge.Myself and many others here have benefited from it and been inspired to do more research then do our own experiments and implementations.As far as this discussion Erik and Ralph just start from different points IMO.

  The Amroc chart Erik mentioned I ran across a few years ago - calculates your room modes in seconds,a good place to start.The site is very informative and easy to understand for us tech challenged folks(me).

 I've got room treatments and three subs,only one sub has DSP included. What a huge positive difference that equalizer makes....if the other two ever fail I know what I'll be replacing them with. My speakers do go down to 20hz but their position isn't ideal for the best bass response even though the mids up are the best they can be in my room. Just my two cents.
