Yes the tweeters do not work in the 550, or the 540, and the 350, and 340 as well.... The tweeters are there just to make the board look better. I wish Yammie would not have done that. Tweeters would really bring the sound out more on the 550's internal speakers...

Squeak, I'm sorry if we failed to respond to you regarding this issue. I wonder how you came to the conclusion that the tweeters dont do anything. The tweeters are real tweeters and are absolutely connected to the power amp. Yamaha could put on a cosmetic thingy that might lead customers to believe that the instrument is more than it really is, but that's not the case. The tweeters may not be as brilliant as you like, but they are working. Neither Yamaha nor any other manufacturer can afford to throw components into a product that dont do anything. I have the luxury of being able to compare the same sample on 2 keyboards, 1 with that tweeter and 1 without. Very noticeable difference, particularly on the harmonics of piano bass notes.
