The goal is clear: retain what matters for audio quality and reliability while optimizing design and manufacturing to offer a coherent package at a more affordable price.\u003c\/p\u003e\u003cp\u003eThis approach notably involves higher volume production methods and field-oriented construction choices. Within the JRX200 range, JBL also highlights transducers manufactured by JBL Professional in Northridge, California, to ensure a solid foundation in terms of consistency and performance.\u003c\/p\u003e\u003cp\u003eNote: Some innovations mentioned for the series (such as the Progressive Transition waveguide or SonicGuard protection) mainly apply to the full-range speakers in the JRX200 family.
