Considering the almost infinite differences in systems, rooms, and personal taste, adding any subwoofer/s is quite a subjective subject.
Subjectively, I find the performance needs for my primarily analog music only system much greater than for my home theater. Home theater controllers 80Hz standardization makes the need for an on board digitally EQd subwoofer unnecessary.
In an in home music only comparison with two other subwoofer owners and their subs the only noticeable difference between digitizing the extra low frequency signal was the ease and preference of system and room integration and their stunningly superior performance. The narrowing sonic differences between analog vs digital doesn't seem to be audibly present at this region of the frequency band especially when considering their equalization and optimization control advantages.
To answer the original poster question, yes it is about the quality of integration. In our comparison the REL Studio III was the quickest to set up as per the manufactures instructions. Unfortunately, it was unanimously the poorest performer in all other aspects. To be fair the most expensive and finely crafted British made Studio III was the oldest sub in the comparison and I haven't kept up with any of the brands current advancements. The other two digitally controlled subwoofers in the comparison are currently using substantially improved second generations of control.
The ultra low Hz is simply icing on the cake.
