Thank you Vagro.

Does the pa500 also have a "Woofer" as in the 1500? I think a woofer really pumps up the sound even if the sound quality of the board isn't good.

My psr 1500 didn't have tbe best sounds. In my opinion, it was basicly a "4 variations" version of all the cheaper Yamaha boards, with basicly the same sound quality. But the woofers it had really added a punch to the music.

Does the PA500 have woofers?
