Okay, time for the stupid question....school me. I have a Velodyne 10 inch subwoofer in the same system as my Fortes. I understand that diameter difference may explain why the 12 inch woofer on the Fortes won't move as much as the 10 on the subwoofer. I know the Fortes are producing some bass when on my receiver they are set to "large" but the Fortes don't generate enough bass to cover general music needs unless the power supplied is high. In my mind, excursion is proportional to noise output (not counting in to effect that different frequencies have different excursion measurements. I understand that though) and I'm wondering if it is normal for the Fortes' 12s to have almost no excursion. Would replacing the caps or xovers help this?
