Meets the highest demands: high-fidelity performance of studio monitors that provide full fidelity sound, consistently as a speaker housing with Bayer MaterialScience polyurethane monolayer foam
Located in Wedemark, near Hannover, Germany, K+H (Klein+Hummel) Vertriebs- und Entwicklungsgesellschaft mbH is a subsidiary of the Sennheiser Group and known for producing top-tier audio equipment. Their latest offerings—O 110, O 300 D, and O 500 C—stand out in the professional audio market due to their exceptional sound neutrality, precise stereo imaging, and accurate bass reproduction. These monitors are widely used in recording studios and broadcasting environments where sound quality is critical.
The design of these speakers incorporates advanced technology, including a high-frequency mid-range bass system integrated into the bezel, which helps deliver superior sound clarity. The rounded edges prevent sound diffraction, ensuring a more natural and accurate listening experience. The speaker enclosures are manufactured using Bayer’s Baydur® 60 polyurethane integral foam system, which allows for flexible structural design while maintaining excellent acoustic properties. This material is known for its ability to replicate fine sound details, making it ideal for engineers who need precise control over sound propagation.
In addition to its technical advantages, the polyurethane system also provides a shock-absorbing effect, minimizing unwanted vibrations that could interfere with sound quality. K+H applies attractive coatings to high-quality plastic surfaces, ensuring that the products meet both functional and aesthetic standards. According to Frank Kirschner, head of sales at Klein+Hummel, the use of this material not only enhances acoustic performance but also offers cost-effective manufacturing benefits.
