Perhaps the lower bass issue has to do with the use of pleated paper surrounds on the woofer. These types of surrounds do a terrific job of damping vibrational energy of the cone, and thereby make them sound very clean in the higher frequencies that the speaker is called upon to reproduce, but, they also limit the excursion of the cone so that for any given diameter of cone, they cannot produce as much very deep bass.
I happen to like the sound of woofers with pleated paper surrounds, but, I am not one to insist on gobs of very low frequency energy. My speaker runs twin 12" woofers with pleated surrounds.
