Upgrade from martin 40i

I recently have blown my tweeter in my martin logan motion 40i

I was able to increase funds to about 2500.  What would be a good upgrade from the 40i?  Mainly listen to music a few movies.  Room is 25 feet long by 15 feet wide.  14 foot ceiling. I have a ml 800x subwoofer. Ran by athem 720 mrx.
