Active speakers are NOT 1000 times better, IMHO. They're not even two-times better than a well matched conventional system.
I agree - Twice as good for Active vs non-Active Speakers is closer to the difference and I agree that room acoustics/speaker placement can make this order of difference too (although most audiophiles know about this fact whilst fewer are aware of the advantages of Active Speakers or the problmes of matching speaker and amplifier).
1000 times better is just pure ridiculous hyperbole - nobody would believe that (I think this statement is tongue-in-cheek heavy handed marketing on the part of Meridian founder Bob Stuart - nobody in AES would buy this statement and Bob knows this!).
