Sorry, I didn't see this thread until today. I have heard Mag 20.1s paired with a pair of JL Fathom F212s. The sound was choherent and seamless. The sub was undetectable as a separate entity while providing strength, extension, and dynamics from 40 Hz down to 20 or slightly below.
JLs are crazy fast and linear over a broad frequency range. I'm not sure what your budget is, but JL's new E-series makes their subs more affordable than ever.
