I thought a few of you would like to see some power testing results since I've seen Obsidian subwoofers mentioned in a few threads. We had a little fun a few months ago putting the 12" through a pretty brutal test. The test involves an open baffle and a 60 Hz pure A/C sine wave that we are able to adjust the output on. Here is a graph showing how the Obsidian 12" performed along with a similar priced driver put through the same test.
