I also agree with Duke's suggestion to felt the tweeters. Just go to any fabric store and pick up some felt and double sided scotch tape. You can choose a color to match the speakers.
Carefully cut a hole slightly larger than the tweeter and apply it to the speaker. You can then add additional pieces, layering the felt until you reach the sweet spot in terms of what you want to achieve.
Completely and fully customizable sound in terms of what you are looking for at a cost of around $6 to $7.
I've done it. It works. If it doesn't, you're not out very much.
