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!

Speaker manufacturers need to quote frequency range within decibel limits.

If Cabasse quote 41Hz at the bottom end it might be -3dB or -6dB, or worse.  Whatever, at the usual rate of roll-off there will be nothing at 20dB.  If OP is hearing a significant signal then it might be room effect but more likely check his Dirac.

For those interested bottom B on a Steinway Model 6 is 31Hz.  The bottom of a string or electric bass is 41Hz.

Those wishing significant musical output down to 20dB definitely require sub-woofers with these Cabasses.  I wonder what instrument they are listening to.

I usually find if someone is asking if they need subs, they are not satisfied with their current bass...

20Hz?

Give me the titles of all 20Hz music you listen to and I will solve your issue, I am sure.
