The Unison Research MAX 2 is engineered for optimal acoustic performance through meticulous design and component selection. By focusing on physical principles, this speaker achieves a seamless balance of efficiency, clarity, and dynamic range.The Unison Research MAX 2 employs advanced acoustic engineering principles to optimize sensitivity and impedance, ensuring compatibility with valve amplifiers. The innovative woven composite diaphragm of the 15" woofer reduces harmonic distortion while enhancing low-frequency reproduction, supported by a die-cast basket that maximizes structural integrity. The compression driver utilizes a neodymium magnet and an aluminum diaphragm to ensure responsiveness and temperature resistance, minimizing sound coloration. The cabinet design features a front-firing reflex port to enhance low-frequency extension, while its internal bracing and open cell polyurethane insulation reduce unwanted resonances, ensuring accurate sound reproduction. The asymmetrical crossover design, with carefully selected high-quality components, smooths the impedance curve to create a dynamic and defined sonic experience across the frequency spectrum.Key Features 15" Woofer: Utilizes a vegetable and carbon fiber diaphragm for reduced distortion and enhanced low-frequency performance.
