I just bought a set of AR5's off of eBay. One of the speakers sounds scratchy when the volume is low. I took the grill off and the woofer has a new surround, albeit very sloppily done. I gently pressed near the the top of the woofer and the scratchiness is gone. Speaker's DC resistance measured 6.1 ohms.
Is the woofer blown, should I try replacing the surround, or something else?
