I've uppgraded from an old Sony ES AV amplifier to the pioneer. I've set up everything correct with NO subwoofer selected, and then tried various settings for the other speakers. The final setting i made was front=big cetner =small rear=big. The problem i have is that i feel that there are to little bass when watching movies (it's ok when listening to music). The indicator for the subwoofer channel blinks in the display but i don't hear that bass in the speakers.. Ok there is some bass but i feel that there should be more. Compared to my old SONY it's a BIG difference, but that could just be that the sony adds bass do the pioneer sound is more true to the source? or? Any comments or ideas? If i change the EQ to have 3-4db extra bass in the front speakers and then add anohter 4 with the tone control it is .. ok, but should that really be neded? Does this reciever require a subwoofer to be able to sound ok? Can it be a problem with downmixing the subwoofer channel to the fronts etc? - YES it's set up ok.... The Automatic setup even lowered the bass response on my front speakers so it's strange.... I don't want to add a subwoofer. Any pioneer owners that can give me their input ???
