Had an SL2000 tweeter go bad on one of my Monitor 10B's. Decided to go with a pair of RDO-194's ordered directly form Polk. They arrived today:) Took one out of the box, no gasket. Maybe should've ordered those. No label on the back of the magnet like the old ones saying manufacture date or "inspected by", no nothing. No indicator on the contacts saying which one is positive. Looks suspiciously like "made in China". What have we (they, Polk)come to? Little piece of paper say I my have to drill pilot holes (no big deal) but that's about it. Does it matter where I connect the black wire?
