I was reading a post on Avsforum and some guy said that you can make bright speakers warmer by putting Felt pads around the tweeter. When I got home from work; I actually tried it and it actually works. It only took about 10min and its very inexpensive to do. I bought Felt pads at Home depot (7/8" in diameter) with adhesive side to it. I actually sliced off the adhesive side to make it thinner. I place the felt on top of the original felt of the tweeter and done.

The sound is muffled but in a good way. The detail is still there but less bright. I actually love the way it sounds. It sounds close to like the Rockets 750 sigs.

Note: The sound is very subjective; If you do this mod and don't like it; you can always remove it.

Peace.
