About the K1

The Vivid Audio K1 is a 3.5-way vented floorstanding loudspeaker featuring six aluminum drivers, including four 6-inch woofers arranged in a reaction-canceling configuration with front and rear facing woofers to minimize cabinet vibration. It uses a unique dual-port design to cancel reactive forces, allowing a visually transparent enclosure. The midrange and tweeter employ aluminum diaphragms formed into a catenary shape to push breakup modes above the working range, with backwaves absorbed by tapered tubes extending to the rear of the cabinet. The crossover frequencies are at 100 Hz, 900 Hz, and 4 kHz, with a fourth-order network at the highest crossover. Drivers are decoupled from the enclosure by pliable O-rings to reduce resonance. The cabinet is made from a complex loaded carbon fiber filled polymer with a high gloss automotive finish, designed to minimize resonances and diffraction. The K1 delivers a frequency response from about 39 Hz to 41 kHz (+/- 2 dB), with power handling of 300 watts RMS music program and a sensitivity of approximately 89 dB at 2.83 V/1m. It weighs 38 kg and stands about 1095 mm tall. The speaker is praised for its openness, speed, and dynamic sound, requiring high-quality amplification and source components to fully realize its potential. It was
