Well I fluffed up and rearranged the fill in my 150 and added some more of my own, about 25% more, it sounds clearer and more open to me, without being muddy at all. I didn't "screw with the m22" since I love how they sound. I"m not satisfied with how the 150 sounds so I experimented and now I'm more satisfied, it sounds closer to my 22's now.
