Discovering just how resolute this speaker is makes us wonder if we ever got the best out of the B1 some five years ago. Somehow we doubt it. The Vivid K1 is undoubtedly one of the finest loudspeakers on the planet. Lord only knows how the Vivid Giya manages to improve on it’s performance. Jason Kennedy, HiFi Choice (UK)

This award-winning speaker is the result of some extensive research and very innovative engineering. It contains all the qualities one would expect from a world-class loudspeaker.
The Vivid K1 floor-standing speaker is the largest of the OVAL range and utilizes the original unique Vivid Audio cabinet form.
When designing the Vivid K1, the Vivid Audio engineers wanted to gain the bass response of a larger speaker yet retain the agility and speed of a smaller design. Through extensive research, they perfected a reaction cancelling bass loading system that, when combined with a newly developed crossover, delivers progressively focused power with increasing frequency. The result? All the bass expected of a much larger design yet with the coherent detail of a simple driver.
The Vivid K1 floor-standing model is the largest of the range which employs the coupled front and back bass driver system and integral stand.
Vivid K1 employs a single D50 mid range driver, between 900Hz and 4kHz with the range beyond being handled by a D26 tweeter. Below 900Hz the Vivid K1 uses four C125 midbass drivers, two mounted on the front baffle and two mounted on the rear baffle of the cabinet. These four drivers are internally coupled in pairs via screw tensioning units for reaction cancelling. Through the use of innovative crossover circuity, all drivers receive the same signal at frequencies below 1ooHz while above this point drive to the lower and rear drivers is progressively attenuated leaving only the front upper driver to operate all the way to 9ooHz to ensure good vertical dispersion at crossover.
Fourth order filters ensure phase coherence through both main crossover points resulting in a seamless and symmetrical polar performance. Integral to the Vivid K1 enclosure is the stand, made from the same cast carbon fiber reinforced polyester compound as the enclosure, the stand provides an exceptionally stable footing further guaranteed by the use of a total of five spikes mounted around the periphery of the base. Adjustment of the two rear spikes and that at the front sets the correct attitude while the remaining two can then be brought into contact with the floor for maximum safety. Within each of the streamlined arms are hidden separate conduits to guide the Van den Hul® interconnectioning cable away from the two internally mounted crossovers into the base. Precision machined gold plated terminals are disretely located at the rear of the base to allow a visually unobtrusive connection to the outside world.
