Eton silk some vs the Magnesium Ceramic Dome?

Good afternoon everyone..Happy 4thof July. So I have never used a Eton tweeter before? I have use seas textile domes.and other planner and tweeter's and the L.G. metal some tweeter's from the past..So I have a few questions? I would really like to use the Eton magnesium ceramic dome model number 29HD2. I also like the sound of the silk Dome model number 28SD1. So can anyone tell me how the Magnesium Ceramic tweeter's sound like?Are they bright or tinging sounding? Thanks Jeff
 
Thanks for the advice on the SB acoustics tweeters. Also they are 4 ohms and dip down to 3.2 ohms that will not work for my needs. The Eton is 8 ohms but, dips down to 6 ohms and my amplifier can handle that not a 4 ohms load. That's why I was looking at the Eton tweeter's in the first place. Sorry for leaving this detail out.
