they're still not bass heavy by any means, but at least some basic low-end treatment is recommended - for both the a7 and the p11a though.
btw, check out the genelec 8040 too....about the same pricerange, but a very different sound. for me it was between the p11a and the 8040, and i went for the adams, but it's definitely a matter of taste.
genelecs have a rounder sound, a slightly more hyped bottom end, sweeter high end, and the imaging was superb.
the adams are more analytical....genelecs can sugar coat some problems in the mix, whereas the adams push them right in front of you. they don't have that slightly hyped bottom end, and a very different high end response. the stereo imaging is as good as the gennies, but i'd say the genelecs are better at showing the space of a mix, i.e. depth (reverb, delay, front/back staging etc).
