On my B&W 803D, I use Kimber WBT 0681 spades 5/16" and the plastic slots would also take 1/4".
What Spade Size to Use on B&W 803S Binding Posts
I am trying to buy a set of custom speaker cables. What size spades should fit perfectly on the binding posts of B&W 803S speakers?
The binding posts are WBT--0765. The specs state it would take 1/4" or 5/16". But I doubt that either one would fit because of the opening of the external plastic slot. I am afraid that the spade would not fit in the opening before it reaches the actual binding post. I hope I described it correctly.
