Hi guys, I just retired and brand new to home theater systems. I bought two 8060s for my front and two for the back. I am running a Denon 4500. What I am noticing all the time is that my right speaker the woofers will play quite loudly but the Dolby speaker on top has hardly any sound at all coming out. My left speaker is just the opposite, it has Strong Sound coming out of from the top upward firing speaker but the two Wolfers barely have any sound coming out at all. is this normal? Is this the way it is supposed to be or do you think I have a speaker or a AVR problem? This stuff seems quite confusing If you are brand new. Thanks
