I picked up a pair of Polk Monitor 10's yesterday and the cabs were pretty beat up. Both speakers work fine and sound good.
4 MW6503 6 1/2" drivers (will fit SDA-CRS too), one dust cap pushed in. $20 each see pic
2 SW100 10" passive radiators. $20 each see pic
2 SL 2000 tweeters. $15 each see pic
2 stock crossovers. $15/pair
2 grill covers w/logo pins, clean & scratch free. $10/pair
I also have a pair of Polk Monitor 7 grill covers that I purchased from Tom Z alas they don't fit my 7C's.$10 pair
