Many people, esp. non-audiophiles, are so used to the artificial 5-10dB "hump" around 100-200 Hz built into many speakers, radio broadcasts and also TV broadcasts that the honest humpless bass of the Maggies sounds thin by comparison. I totally grant that Maggie bass below 40 Hz is MIA, but I'm talking about excessive bass in the upper bass region that creates the illusion that the bass response is better than it really is.
Even after extensive auditioning and eventually coming home with a pair of 1.7s, I was unprepared at how "quiet" Maggies are--that a lot of what I was previously hearing on playback was enclosure resonances, which the Maggies don't have.
I do have a pair of small high-powered subs to fill in the 35-45Hz range. It adds oomph and dynamics to the presentation, while not adding a hump to that upper bass range.
