Couple of rookie questions-- Is it OK to mix speaker brands like Polk up front and Energy in the back? Also, are bookshelf speakers the same as the rear speakers?

Any help is great thanks!

Is it OK to mix speaker brands like Polk up front and Energy in the back?

some might say no, but I would say no problem - unless they are radically different, still any well-designed amp should take in stride

are bookshelf speakers the same as the rear speakers?

To me they are not, though many people do use bookshelf speakers as rear speakers...............unless you are very demanding it should be fine
