I would guess that if the Spicas didn't have enough bass for you, the small Maggies might disappoint you -- as dipoles, placement is crucial to having any sensation of bass, but even ideally located, the panels may not have enough area to offer the sort of convincing solidity in the low end that you may want. My impression is that Maggies also like and need a fair amount to power -- its always difficult to predict whether small amounts of power will do what a specific person wants, so I suggest you actually try them with your amp before deciding. I used a pair of II (I think -- not the biggest, but still big, whatever the model number is) with a Dyna Stereo 70 and was perfectly satisfied, but I also was happy with the same amp and Dahlquist DQ 10s, so its obvious that I am an outlier.
