Hi all, I have a quick sub question:

I'm finishing up two sealed 2.0cuft boxes. Each will house a Dayton RSS315-4 12" sub to complement my Statements Monitors.

Each RSS315 has a thin piece of what looks like gasket foam preinstalled. Do I need any additional sealing material to get a good air-tight fit against the baffle (1.75" MDF with countersink)? Do I just mount the driver as-is?

Thanks!
