For over forty years, Harbeth has been producing top-of-the-line speakers with innovative technology behind every model. Based in England, they began working with BBC on research and development. The company eventually decided to branch out from broadcasting and introduce new innovations, such as its RADIAL™ cone technology. The new audio modifications Harbeth made became very popular for customers seeking the best quality sound possible. Their mission became clear: to raise the technical standard of the entire global loudspeaker industry through their remarkable audio improvements. Every Harbeth speaker incorporates the RADIAL™ cone feature, which is one of the biggest advancements in loudspeaker technology. Because of this innovation, each speaker has unmatched clarity and resolution. In particular, models like the Harbeth 40.3 XD are known to sound closer to live music than nearly all competitors. Similar to the Harbeth 40.3 XD, the Harbeth Super HL5 XD speakers also have great quality but are more affordable. All Harbeth loudspeakers have unbelievable audio performance and are one of the most innovative brands to date. Overture is a proud dealer of Harbeth products, selling customers the highest quality loudspeakers from Harbeth. Interested in purchasing a new Harbeth speaker?
