I am looking into buying some USED Paradigm atoms for 100 dollars (is this a good price??). My question is I have the Pioneer VSX-D812K receiver which is supposed to put out 100 watts to all the channels. The Paradigm Atoms are rated for 10-85 watts if I'm not mistaken. What would happen if I used these speakers? Also, if you can answer what you think of the price! Finally, I'm thinking of pairing these as rears to my front Polk RTi38s anyone think this would be a BAD idea?
