Query: Don't buy it

I give this three strikes. 1) the bulky "power brick" mentioned by others. This would make portability a bear and if you don't need portability buy at least a 2.1 system! 2) Weak preamp. Some of my tracks simply will not play at useable levels because the normalized sound levels are too low for decent playback. 3) Very low sound levels before distortion!!!I was impressed by the passive radiator idea, many of the finest high end systems use this approach to try to achieve the low end and punch of a ported system while preserving the tightness and upper bass range clarity of a sealed system. These speakers do acieve fantastic sounds - but only at low listening levels, and with loud tracks. They'd work in a hotel room, that's about it. I hope Philips re-does this speaker & gets it right!I'll be choosing between the Klipsch ProMedia Ultra 2.0 and the Bose Companion 2 Series II 2.0, both at $99. Why pay less for use-less???
