“These are really nice except they will not work for SONY SA-Z9R rear speakers. Sony uses some odd, undefined, metric mounting bolt, which is smaller than 1/4 -20.”

the hole in the back of those speakers is M5 thread - a 1/4 to M5 thread adapter can be used to mate these brackets to those speakers very cleanly. I used mcmaster.com product number 91649A151 and it works well
Sorry, there was a problem. Please try again later.I finally found speakers from Von Hous, that listed for $29.95, on sale for $21.95, but only $9.95 (for a pair) on amazon. These contained regular bolts in both the 1/4x20, and the metric size the Sony SA-Z9R uses. I returned the other mounts. Note, it said they were metal, but in fact they were plastic, but they worked fine.
Sorry, there was a problem. Please try again later.Find out what your speaker threads are. I bought some LG rear speakers as the threads are M4. Thor labs had a 1/4-20 to M4 for fairly cheap.
