Hey everyone, I just picked up a used Goliath Junior II 2x10 for $200 from a reputable and well known guy here in the phenix area. I did notice that one of the speakers was replaced when I bought it, but when I pulled the speaker out of the cabinet, I saw that it was an OEM replacement speaker. Here the issue, the cabinet sounds great at nominal volumes, but when I start to really push it, the one new speaker tends to rattle. I can isolate the rattle to coming from the speaker cone itself and no the cabinet, and i checked for loose screws. Nothing really seems to be wrong, but has anyone else run into this problem where it sounds fine at medium volume and rattles at high volumes? I want to be sure it's not something minor before I go get a replacement speaker. BTW I run the SWR 2x10 with an old British Ashdown Mag400 head.
