Sparkles all around!

Black and white are the standard colors of K-array pro audio speakers and subwoofers but you are able to customize them by selecting one of the colors in the RAL palette.

This is the perfect way to match products with the architecture and design of your venue, or just to fully express your unique personality and attitude. The extensive RAL chart gives you the possibility to find the color that best fits your preferences – a specific shade for your system to make them unique or ultra-bright.

Your color choice not only affects the aesthetic appearance: colors can also affect and represent an array of moods, emotions, perceptions and sensations. So appeal to your customers’ senses and make it original!

Any of our elegant finishes developed from unique treatments will provide a distinctiveness and allure to accommodate even the most demanding tastes.

Premium brushed or polished stainless steel finishes are available to give speakers and subwoofers the chameleon-like ability to reflect their surroundings and blend in with the background.

Conversely, a gold audio solution will radiate throughout the venue like your very own star. The 24 kt gold plated stainless steel finish is a combination of technical expertise, quality design and high-caliber aesthetics guaranteed to make everything around it shine.
