I agree with Martykl...a good combination is tough to beat in my opinion.
I cannot say if my own X1/Grand Slamms plus Velodyne DD18 would work for others...but it works for me. And I know more owners of the big Wilsons who DO use Subs with them (in parallel...not cutting off the Wilsons) than those who do NOT use them.
At below 40hz, I honestly find the solidity of foundation is wonderful, and I find the 'blending' to be quite good after months and months of fine tuning every few weeks.
