... accept either balanced or unbalanced signals for integration into a variety of studio setups. Low Resonance Enclosure Design HS Series cabinets are designed to eliminate unwanted resonance and increase the accuracy of sound reproduction to their extreme limit. The enclosures are constructed from a dense MDF with a damped acoustic response. HS Series engineers also employed a traditional three-way mitered-joint technique. Common to architectural design, this construction firmly anchors the corners of the enclosure to improve durability and eliminate unwanted resonance that can influence overall sound Noise Reduction Technology Speaker port design can greatly influence the clarity of overall sound. Often a vortex at the either end of the port can generate air vibrations inside of the port, causing unwanted noise. By adopting a noise reduction technology that incorporates an analysis of a visual representation of the sound, Yamaha's engineers are able to control and reduce the vortex. Through this analysis Yamaha has arrived at a port design that reduces noise up to 6dB Controls and Connectivity HS Series full-range models feature two response controls with settings that allow them to adapt to the surface acoustics of rooms of varying shape and size.
