I have a pair of PSB Image T6 speakers, which most people would consider full-range speakers, and may be somewhat comparable to yours as far as bass range is concerned (Polk claims response to 20 Hz on your speakers; that is ridiculous; pure bull; they go down to 35 Hz or so at -3db; no lower).
I used them for about 6 months with no subwoofer, and they are good down to below 40 Hz, but I definitely missed some lower energy from string basses and organ music, large drums, etc.
I wanted to get one of the nice subwoofers from Rythmic, such as the F12, but I have a space problem and they just were not going to fit.
I settled on the NHT B12D subwoofer, which uses a sealed acoustic suspension design to pack a great 12" subwoofer with a 500-watt RMS amplifier into a small package (a 14" cube) that just fits my space requirement.
I watched a movie last night (The Red Baron), and the aircraft engines were so realistic that I thought I was back in the pits at the dragstrip; incredible. The visual and sound effects in that movie blew us away; very cool.
The kettledrums in the orchestra are also nicely taken care of by the subwoofer; good stuff.

I realize that a sub is needed in a home theator system to bring out all the explosions and various sound effects in these HD movies, but how about a sub with a 2-channel music only system? .... no movies, no tv
I will be using a pair of Polk RTi A7 fronts and a pair of Polk RTi A3 rears. The front speakers are powered by a separate 100 w/ch (8 ohms) power amp, and the rear speakers are also powered by there own separate 100 w/ch power amp.
Seems to me almost everyone nowdays is using these audio systems for a combo of music and home theator, so I can see why they usually include a dedicated sub ... but again, my system is music only.
Sub ... good idea ... waste of money?
BTW ... Some may ask why I am using 4 speakers with 2-channel music ... I just like the sound better (more "spacious" sounding to me). No other reason.
