OEM wall mounting brackets for NHT SuperOne (Super One) speakers, in black.  They have very light use, having been in storage for the past 20 years.  The ball pivots lock securely, and the vibration isolation pads are present.They're designed to hold the weight of SuperOne's, so they'll easily hold SuperZero's which I believe share the same 1/4-20 center rear mounting hole.  (I think the same wall mount brackets were actually sold for both models as $90 options.)Combined shipping savings available.
