Well I tried again (safely on my workbench) I know know that the grills covering the woofers are glued on. the previous owner must have broken the tabs and instead of getting new grills or properly fixing the old ones just COVERED the face with glue and clamped them on until they dried. Its so tightly glued on that i fear i'll pull up the veneer while trying to separate the grills. unlike the sides with the working tweeter grills there is NO gap between the grills and the speaker housing. Oh well.
