Ok, so i picked up a promethean p5210 used from guitar center for under $200 with a year of pro coverage. Great deal, but when i got it home and plugged it in one of the speakers seemed to be pretty obviously blown. As i crank the low end it just crackles and pops. One of the speakers sounds incredible, the other like crap.So here is my dilemma. Do I: Return for a full refund and effectively miss this deal. Or Wait 60 days until my pro coverage is available to use and ship it back for repair. Or Take it to a repairshop around town and just bite the cost. Or get a replacement speaker and try to replace it myself. Please help! Thanks.
