Hi to everyone! Im a newbie in this world of hifi systems, and im very interested in having a nice set-up and needs your help! I have an onkyo av receiver tx-ds777,2 infinity primus 150, 2 polk audio r30, 2 bose 401 and an infinity bu2 sub. As far as i know the av receiver is designed for 6 ohms spkrs only, the infinity and the polk audios are I thinks 8 ohms. while the bose 401s are 4 ohms...would I be able to hook up these speakers to my receiver without damaging it? coz i heard that if u use a 4 ohms speaker into a 6 0r 8 ohms receiver, it would toast the receiver! Is this true? and Is it safe to hook my 8 ohms spkrs into my onkyo av receiver which drives 6 ohms only as it says at the back of it? Pls help! Thanks!!!
