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!

It depends.  Have you measured your respone with pink noise at the listening position? 

Subs have flexible placement and may be able to boost the low end and fill some holes in the bass if needed.  

If your response is smooth then I would not add subwoofers.  It takes a lot of work to get them to sound perfectly integrated.  

You have more than enough amp power to give your speakers a full range sound.  

A great full range speaker is the best way to go for me.
