The parts total when Danny did the video was $245, this is quoted at 13:00 minutes; the sheet of No-Res adds $50 (some folks opt for this; some folks don't). My hypothesis is Dynaudio elected to use the parts they did for profit, rather than any hypothetical impact on the sound. As for a flatter response being less immediate, less lively...hard to say, as the room is the biggest factor of all. And, I'll add that my big Dyns are exceedingly neutral, but have outstanding speed and immediacy; a term I've coined as "dynamic slam". They scale from piano to fortissimo extremely quickly and cleanly, and are like electrostatics in this regard.
