Just unpacked my set up and am now trying to get it working properly. I have the sub connected both at LFE and Hi Level. On the Hi Level I have to turn the volume down low to avoid it booming but then when I play some heavy bass notes such as the opening to Sting's Brand New Day I can't hear the bass. I am wondering if it is the room as we have tiled floors throughout so I wonder if I should put the sub on a rug to reduce the boom so I can turn it up? The room is very large about 4m x 12m so I didn't think I would get any boom but... It's also in a corner so I guess I should try moving it a bit Any other ideas?
