Hello, I have a Marantz SR8000 and a HSU VT2 sub. I calibrate with Avia and set my amp to stereo. When I use the pink sound the bass signal seems to come from the front left and the sub. So basically I'm getting low Hz's from the front speaker and the sub at the same time. I have the fronts set to small. Do you all hear the same problem or? I test Avia with the front left going to sub to set up the balance with a radio shack sound meter. But getting bass out of both speakers is screwy. Shouldn't it be High pink sound coming out of the front left and then when shooting to sub. Just the bass only coming out of the sub and not the front left at the same time. confused!
