Mods for bright speaker?

I was looking at the Monitor Audio Bronze 2. It has been reviewed better than Acoustic Energy EVO 1 or Jamo but I'm afraid it will be too bright with Yamaha receiver. What Hi-Fi ended up pairing the Acoustic Energy (instead of B&W 303's)with a Sony for just this reason.
I've heard of 1) tissue paper over the tweeter and 2) using felt rings around tweeter. Is there any simple mod to the x-over (add a capacitor)? Or should I just go with the Acoustic Energy?
