I just set up my HT with RTi A7s for the mains, Csi A6 for the center, FXiA6 for surrounds, and had some OWM 3s that I had for the back surrounds. I'm using a HSU VTF3 Mk 4 for the sub and an Onkyo 709 for the receiver. My problem is that, in my opinion, the sound is underwhelming. I was expecting much more from this setup but I feel that I really have to crank up the volume but even then it's not that impressive. Does anyone have any experience with this receiver and speaker combo and can anyone offer any advice as to what I might be able to tweak? Thanks in advance for any replies.
