Rick I bought a 1000' spool of quad shielded Tributaries RG6 for all of our in-wall runs and had some subwoofer cables made up as well. My wall plates for the subwoofers terminates with female F connectors and the F connector male end of the made from the spool of RG6 subwoofer cable plugs into the wall plate. I didn't need to use any adapters because the folks who terminated all of my wall plates also made the subwoofer cable for me.
The adapter you show would be for the wall plate terminal end while the adapter that Marks shows should be for the connection to the Subwoofer itself, right?
