I have a very similar situation to Riasillo, I have an Onkyo 609 avr connected to polk lsi9 speakers above tv with hsu research stf1 sub in a big entertainment center with turtle back ceiling. I am just doing a lcr with a sub configuration and looking for a center speaker. Jmcgrogan2 thank you very much for your explaination because its very clarifying and helpful. I am trying to figure out what speakers I can use with my lsi9's on a college students budget. Really no question here but just saying thanks for your explanation it helped me.
