I'm working on the rest of the data right now. I really thought I'd have it all compiled before anyone woke up, but I guess not. Give me another hour or two and I'll post photos and test data in the ProSpeakers forum, with a link to it on the Prosound Shootout website. Then we can all comment on what we learned as well.About the power levels, I wanted to see if I could reach a mechanical limit or if failure was always the result of thermal stress. I also want to find what the limits are in various conditions. So far, I have not been able to create a mechanical failure, they've all been thermal whether by heat soak or instantaneous burst.
