One possible advantage of two tubes over a single tube is the blower and airflow.  Sometimes using two smaller tubes will require less airflow and have less backpressure than a single tube.

REPLY: 

You still haven't elaborated. For a given power output, why are two tubes 
(properly chosen)  better than one (properly chosen)? I see several drawbacks 
and no advantages.
