Not sure what you mean with the AVR pre vs integrated. Basically everything is run through the Marantz and then I have the marantz hooked to the Halo and then the speaker wires from the halo going to the towers. Sorry for my confusion on this.
@kota1 :
Here is a pic of the room if that helps. Right behind the photographer in this pic would be a large island and kitchen. The living room is 16’ Wide and we sit about 12’ from the speakers
I don’t know anything about frequency response, but I’m not sure what I can change exactly since it’s our living room. There’s no way I can put up acoustic panels or any treatment.
