Has anyone experiment with the amount of polyfill in the mid/tweeter section? I added about double the current amount and am doing some A/B mono tests, it has peak my curiosity. Definitely gives them a different sounding midrange than stock. I always liked how my SDA 1s mid range sounded and those are stuffed tightly with polyfill in stock form. Not saying that technology hasn't changed since then, and of course they are two different monsters. Anyone tried this?
