This made-in-Canada flagship Bison Twin Tower is a stunning result of our continued evolution of expertise in loudspeaker engineering. Designed to allow listeners to truly experience the full-scale of musical vistas, this speaker is so immersive that you will get completely lost in the music. It pairs well with a broad array of electronics and when used with a well-designed amplifier, it will provide a world-class sonic experience that will satisfy the most discerning tastes. The Bison Twin Tower combines two high-performance woofers that operate in the same frequency domain, allowing them to provide a lush, thick midrange and the ever-important bass fullness, which is unique in the floorstanding speaker category. Thanks to carefully selected components, custom driver development and evolved hard-wired crossovers, this tower manages to achieve symbiotic, synergistic and remarkably musical relationships between all of its interconnected parts.
