You probably can't beat the iLoud with respect to weight:loudness ratio, as it is only 1.3 kg / 3 lbs. The Beolit 15 is already 2.7kg/6 lbs.

I wonder why the Genelec 8010 put out so little highs compared to Beolit and even Klipsch. The Klipsch has been criticized by some to be slightly muffled, but compared to the Genelec it's extremely crisp. I hope everything's ok with them, I got them as B-ware. But I think they are ok, the highs are not absent, just much lower in volume. I remember other Genelecs also had less highs compared to a Bose Sounddock... Maybe it's part of the neutral character, and these consumer speakers are more and more tuned for bass and extreme brightness...
