I know you're looking for new speakers, but here's some info if it's useful for you: I have ML 40i speakers and thought I had blown my tweeters. I called ML service and they sent new tweeters immediately, at no charge. It was an easy install, took about 20 minutes for both. Great service from ML. Best wishes!
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.
