I picked up a pair of Advent 2002 from the thrift store the other day which need a little repair. The cabinets look great for their age as do the grills. I have read good things about these speakers, as with pretty much all of Henry Kloss designs. These are a very simple, very classic looking speaker that I couldn't pass for $8 and I look forward to restoring.
I want to try my hand at refoaming the couple woofers, which is something I have never attempted. They are 8" woofers that were commonly used in Advents of that era (Advent 4). I have seen some kits which come with voice coil shims and replacement dust caps while others don't. Obviously, with out the shims I'll have to make sure the VC is centered when gluing the foam to the basket. Examining the woofers with the rotted foam, they seen to hold to center pretty well.
Is keeping the VC centered that difficult to do or should I plan on removing the dust cap and shimming? Any tips?
