Work great but need:
-refoam (foam is still intact and keeping voice coil in alignment but there are surface cracks developing as pictured, refoam kits are about $40 shipped)
-grill cloth (could simply be retightened with fresh staples and would look fine but correct style new grill cloth with superior acoustic transparency is about $40 shipped)
-original capacitors replaced (kits are less than $20 on ebay)
The reason you almost never see OLA without those three things done is they are a cheap way to turn a $250 pair of speakers into a 6-700 dollar pair of speakers. Ergo the dozens of "restored" OLAs on ebay.
