Out of a Kf650 , 10" mid driver, and I'm really not sure where the sand came from, but the driver works fine. the only thing that prompted me to check it out, was it was buzzing on bass notes on sat. I pulled it and found the dust cap about 3/4 off. I'd like your thoughts on if I should just recone it, or re-glue the dust cap and carry on... I foam is in place on the front grill, so again not sure how that much sand got on that speaker, and it's crusted on. On a side note, is there anything "household / hardware store", I can use other than speaker glue to put that dust cap back on.... and please be specific (brand and type please).

Recone if you think any of that sand got in the gap.

Devcon Weld-it is a good off the shelf glue.

I would try glueing the cap back on first since that costs almost nothing to do. Run some tone sweeps and listen for buzz and noise. Shake it around a little to see if there is sand rattling around. If you can't elicit any unusual noise you're probably ok.
 
Re: recone or re-glue?

You can also use Weldbond on paper-to-paper. It's not too expensive and comes in smaller bottles with a tip that lets you draw a halfway decent bead, which dries clear or translucent. Weldbond is very similar to the commercial water-based speaker adhesives I've used.

Like Tom said, worth a try before resorting to a recone job. If nothing else, run your sweeps until all the rust is sandblasted from the pole piece and top plate...
