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!

@bishop148 The point is not more bass! The point is to get the bass right. If the bass is deficient, the ear will perceive the system as being tilted to the highs; if there is too much bass the ear will perceive the system as being muffled in the highs.

 What you say is true, however if you were use a low cutoff filter at 40Hz. With most music I doubt if you could hear the difference. A subsonic filter cuts in about 40 Hz and I could never tell the difference apart from stopping the excess movement of the bass speaker.

 IMHO don't waste your money. There is very little musical content in that octave 20-40Hz and in my experience having too much bass becomes annoying after a while.
