The speaker design is a Full-Range Driver with an Alnico magnet that is supported by the bass drivers for the low frequencies and the soft dome tweeter and super tweeter for mid to high frequencies. The full-range driver minimizes phase distortion found in even the best of the traditional midrange drivers. The ‘Five’ opens a window of clarity, portraying a vivid image of vocalists, the unmistakable depth and width of the soundstage, and the space between instruments. There is a clarity that is rarely found at this price level. The 5 Open also features a super tweeter, whose contributions to room conditioning, bass, and soundstage size are surprisingly formidable.The 5 Open’s External Crossover features a volume control permitting the user to match the Mid and Upper Frequencies to the bass for each speaker. The user can blend them accurately to the bass volume, ensuring a cohesive and synergistic match between the drivers. Moreover, it creates a specific sonic relationship within the room boundaries. In other words, the room walls become its speaker cabinet. The Baffle is akin to fine furniture, with smooth lines without fastening screws. We utilize solid-core pure copper wire intricately woven within the bamboo rear support. The 5 Open is truly a work of Art and represents one of the true values of audio today.
