Question: I know these are the best connection when you have to have some kind of post, but would there be any benefit to speaker wires directly attached? Like your 24 strand version soldered directly to the crossover?
At some point that wire needed to pass through the cabinet. So that makes a cable like our 24 strand braid a bit unpractical. There needs to be some type of connection that allows it to pass through the cabinet.
Also, what is the best connection for on the amp end? Banana? Bare wire?
Bare wire will oxidize and degrade the signal.
Another set of tube connectors is best. If that isn't an option that a spade connection is the best connection for a typical binding post.
