“Are these compatible with the Sony SA-VS150H speakers? Are these mounts compatible with the Sony SA-VS150H speakers (home theater speaker system)? This is a 5.1/7.1 speaker system that allows you to take two speakers and combine them into one speaker allowing you for a 5.1 system or use the speakers all separately for a 7.1 configuration. I only need to know if these stands will each accommodate a speaker. (To clarify, I would have them set up as 7.1 speakers. Seven speakers and a sub-woofer with two of the speakers being each on a stand).”
