x10 its clear sound ,low volume bass .....but for loud music it not enough ,i have a 15 mp2 room its not enough , i recomended for movies and clear sound , for open spaces ,or a big room i dont recomend it....for me jbl extreme 3 was louder then x10 ....but jbl has distorsion on max volume...x10 dont have that ...max volume its clear sound voice and bass ....
