The BlueLine KB1R system is not another plastic lollipop speaker on a stand. A 12" subwoofer for bass and eight 3.15" loudspeakers for medium-high frequencies assure elevated performance, preserving the timbre and quality of instruments and voices. The powered bass speaker serves as the foundation both musically and physically. At less than 13" wide there are no tripod legs to trip on. The top speaker is a true line array element that provides smooth and even coverage of the audience area even at distance. It is visually elegant and does not obscure sight lines to the stage.
Compactness, lightweight design and transportability mark the KB1R and make it easy to integrate into a musician's kit. It is equipped with a carrying case that enables loading and unloading even with small hatchbacks. The bass speaker is protected by a padded cover designed to insulate the sub from bumps and scratches. The designers of the KB1R have chosen materials commonly used for products of a professional quality. Plastic materials have been deliberately avoided in order to preserve the resilience required for professional use. Aluminum, wood and steel have been chosen to forge the BlueLine, perfectly matching the characteristic qualities of the K-array brand. It is no surprise that K-array has developed a product that is easy to transport and quick to set-up.
