The industry as a whole, has not agreed on a good way to measure omnis, including Duevels. One thing I know for certain, is that the sensitivity rating (like "90 db" sensitivity") for true omni is always off in the measurement ratings. This was confirmed when I spoke to Duevel directly. So if an omni measures as 90, it's actually a 92db sensitivity (approximately). The reason for this is that the forward-firing wavefront is only part of the overall actual output of the drivers.

Apologies for necroing this thread. But there's since been measurements released of the Duevel Bella Luna.


No idea how accurate Hifinews' measurements are, and at any rate normal measurement techniques may not work well for omnis. But the published frequency reponse does look like a pretty exciting rollercoaster.
