with a 20x16 room don't get the small HSU VTF2 as I have heard this and it is very disappointing (lots of port noise, because it don't produce that much sub bass)
I have a Servo Velodyne F1800X and it is quite amazing. If you have an extra channel of amplification get a VMPS Standard or look at the SVS subs
