Only the shadow knows for sure!!!

I have the dome tweeters and have had many other fine speakers with 6 ft long ribbon tweeters etc...all good...the ribbon should be really good on the high end...but the dome tweeter in the Salks are very, very good as well.
Go audition them both, play your music and make your decision based on what you hear, prefer and like.
All the best
and
Merry Christmas!!
