Since my Shiva Redux is coming along slowly, I am at the point to start considering stuffing it. But, since the driver and amp are at the bottom of the enclosure, I don't want my stuffing coming in direct contact with them. How have you guys/gals been stuffing your downfiring sonotubes and the like? I thought about using some sort of netting or possibly grille cloth to suspend my stuffing over the driver... however, I'm also concerned with how the cloth/netting might affect airflow. How are you keeping it up?
