The Living Voice OBX-RW4 loudspeaker is the flagship model in the Auditorium Series, designed for serious listeners seeking exceptional musical communication. It features outboard (OBX) crossovers that isolate capacitors, inductors, and resistors from mechanical cabinet energy, minimizing microphonic feedback and parasitic coupling. This design yields a quieter background, greater dynamic range, and a more distinct acoustic space with improved tonal colors, texture clarity, and expressive presentation. The OBX-RW4 offers compelling storytelling with perfect timing and heartfelt lyricism, capable of surprising and transcending expectations. It employs a mid-treble-mid (MTM) driver configuration for symmetrical polar response, low distortion, and high sensitivity, making it ideal for class A valve electronics. The R4 revision includes advanced crossover components and improved time coherence, enhancing tonal balance, depth of field, and sensitivity without bandwidth loss. Cabinet dimensions are 215mm wide, 270mm deep, and 1030mm high, with a rear reflex port and a black textured plinth. The speaker weighs approximately 21-22 kg per cabinet, with a separate crossover box weighing about 5 kg. Frequency response spans 35Hz to 25kHz, nominal impedance is 6 ohms, and power handling is 100 watts.
