room is 12x 18 will be used for mostly music and i have a sub that i bought with my orbs. listen to all music but love to crank up some head banging tunes from time to time. replaced an older system that i used cerwin vegas with and would pop the fuses in the back of those from time to time.the reciever died and i bought the yamaha, picked up the orbs which are awesome but not enough and will be my rears unless i fall in love with the m80s and get the itch for axiom rears but 1st things first. i just want to make sure i have enough power to feed them
