The aspect of Bach's mathematically precise compositions that demanded astoundingly inventive solutions to musical problems is fully evident in the Vienna Acoustics speaker that bears his name. Of note, the beautiful floor-standing cabinet features Twin Balanced Reflex (TBR) loading of the powerful 7" X3P mid-bass driver. TBR combines a conventional rear port with a groundbreaking airflow control port on the front of the cabinet allowing for class-leading bass output and control. Further, the complex front port system provides an extraordinarily compact driver configuration by positioning the refined 1" triple stacked neodymium magnet silk dome tweeter directly in front of the port, contributing to a sonic presentation of power and verve that belies the speakers' compact proportions.
