I got a nice mid-bass boost by using multiple panels instead of multiple exciters! https://www.youtube.com/watch?v=MDxtao6ekBM
I'm going back to basics in this video, setting up a small panel and testing out 1, 2, 3 and 4 driver configurations according to the manufacturer's recommendations.
My aim here is to see whether adding more drivers has an appreciable effect on frequency response (spoiler alert - it can).
Of course, the other main advantage of multiple exciters is greater power handling and potentially lower distortion at a given volume level, compared to a single driver.
