Hello, I hesitate between the JBL nothridge e250p and the YAMAHA YST-SW 315. I have heard that certain subwoofers are excellent for movies but bad for music. I know that the yamaha is good for both music and movies but I don't know if the JBL is good for music like the Yamaha. I will use it for music mainly (90 %) and 10 % for movies. I have a NAD T742 A/V amplifier and Wharfedale diamond 8.4, 8.2 8.c. My tastes are mainly rock music, hard rock, classical, world music. Also, can the JBL and the Yamaha be positioned easily in a room? Thanks for your help, bye bye
