Spendor BC1

If it was me, I might reconsider making the sell. I can certainly understand a buyer wanting to know the drivers condition, but when you got speakers who's grill and cabinet are very difficult to remove to check the drivers, then you're risking damaging the speakers themselves to make this check. And if you did damage the speakers in removing the grill, but drivers checked out, would the buyer still be willing to buy the speakers? I would think probably not. Basically is the risk in removing the grill worth the sell? If it was me, I would sell locally and let the buyer listen to the speakers and determine whether or not to buy from the listening test.

.....or other than that, you might see if there someone in your area who is experienced in sucessfully, and carefully removing (and replacing) grills from speakers like the Spendor BC1. That way you (or they) can check the drivers, and you can rest assure that the speakers themselves weren't damaged in the process.
