I just found out that on all my compression drivers, the connection between the push connectors and internal wiring was not optimal. On one, I got rid of about 1ohm of resistance between the connector and the diaphragm by tightening the bolt that holds the push connector and wire together.
I know these drivers were designed for "field replaceable parts", but why does my signal have to pass through a 1cm long metal [non brass or copper] bolt before it goes through a copper wire again, and the connectivity is depending on the matter in which the bolt is secured in the push connector?
Has anyone altered these connectors in 2420 or 2440 drivers using brass solderable connectors?
