Upon discovering that my acrylic DML panels aren't outputting as much high frequency as I'd assumed, I'm looking for the best solution to tackle the high end.
In this video I explain the measurement error that had caused my misunderstanding in the first place, and try out a pair of balanced mode radiators (BMR) in lieu of actual tweeters.
This might not be a permanent solution, or it might be. I also have another type of driver to test (next video) so I supposed time will tell!
