From the graph you can see that the lowest note on a 5 string bass "B" is 31hz. That is a very low note without a lot of musicality that people can hear. If you want to reproduce this note cleanly and with a lot of volume you will need large cabinets, large speakers and a lot of power. Here is one cab that will get it done:

With a useable frequency response of 30-300hz, sensitivity of 106db, and calculated max SPL of 136db this 36C sub will go very low and very loud. 18" sub drivers move pretty slowly though so you won't get that snappy punch that a lot of bass players like in their sound. Some say they lack clarity and definition. Compare these specs to the most popular touring bass cab:
http://www.ampeg.com/pdf/SVT810EAV.pdf
The SVT810 cab is full of 10", the cab is tuned higher than the 36C with the lowest useable note at 40hz, sensitivity of 100db, and max SPL of 130db. The tradeoff here is that Ampeg has gone for punch rather than low and loud. It simply will not reproduce a fundamental 31hz "B" from a 5 string but it will give you the 1st overtone at 62hz. The SVT will also need a lot more power to deliver the same loudness as the 36C due to the lower sensitivity. With 200watts the 36C will deliver 129db all night long. The SVT810 will need 700watts to deliver 129db.
So if you are a 5 string bass player which do you choose? A very personal choice. Both cabs are a tradeoff. Personally I don't have much use for tones below 50hz but I like the efficiency a larger driver can deliver. I would probably use a really good quality 15" EV sub on the bottom and a good quality 210 top for punch, clarity and definition. This would give me a smooth response down to 45 hz, a sensitivity of 102db and a max SPL of 130db with 500watts. These cabs are also a lot easier to move around than either the 36C or the SVT810. My back is not what it used to be.
These two cabs would be high volume and sound amazing while not breaking your back. Big $$$ though:
