I did the party setting and the speakers are still a bit "Muffled" except for the one - they sound like the signal is not getting completely to them, that the tweeter is not working properly - this on 4 of the speakers with the one sounding normal

Is it possible 4 tweeters are blown? I listened to them closely and if there's any output it's very low.
