The extremely rugged and durable STX Series features an all metal housing and they are the industry-standard for loudspeaker connections. They offer extremely reliable and robust connectors with a reliable locking system. They feature solid contacts with spade-type terminals. Basically they are a no foo way of connecting your speakers and cables that you won’t ever regret making the switch to. They look extremely professional and solid.
