TIME FOR A REALITY CHECKPowered nearfield monitor speakers built on the success of its legendary predecessors that have become a genuine industry standard for their accuracy.Sound Philosophy of HS Series Studio MonitorsWhen selecting studio reference monitors for mixing and music production, one consideration takes precedence above all others - accuracy. Beginning with the legendary NS-10M, and continuing with the MSP and previous HS Series, this new lineup shares a design philosophy that emphasizes sonic purity without any coloring or alternation of the original sound. While many manufacturers seek to enhance the sound of their monitors to make them sound impressive, Yamaha studio monitors are designed to achieve the best possible mix by ensuring that the sound from your speakers is true to the original. HS Series nearfield reference monitors are the embodiment of this philosophy, delivering a concise sound image, high resolution, and flat response.Newly Developed TransducersImproving on the success of the original HS line launched in 2006, the completely redesigned HS series feature new transducers that achieve smooth response over a wide bandwidth and ensure the accuracy of signal reproduction throughout the audio spectrum. By upgrading to a 1" tweeter (from the previous ¾" models) the new monitor series provides an extended frequency range and deliver superb high-resolution sound. Yamaha engineers have optimized the HS powered monitor and subwoofer monitor system for a variety of music production environments.High Performance Amp UnitHS Series speakers employ an amplifier unit perfectly matched to the transducers utilized in each model of the series. Featuring a bi-amp design with a separate dedicated amp for both the woofer and the tweeter, this amplifier unit ensures that each HS Series speaker consistently delivers high-resolution sound with exceptionally flat response across the sound spectrum.Low Resonance Enclosure DesignHS 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 very dense and resilient MDF with a damped acoustic response that is perfectly suited for reference monitors. Drawing from Yamaha's over 100 years of piano design experience, 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 dramatically improve durability and eliminate unwanted resonance that can influence overall sound.Cutting Edge Noise Reduction TechnologySpeaker 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 an advanced noise reduction technology that incorporates a thorough analysis of a visual representation of the sound, Yamaha's engineers are able to control and reduce the vortex. Through this in-depth analysis we have arrived at the ideal port design, resulting in a reduction of audible noise up to 6dB. The utilization of this state-of-the-art technology allows HS Series studio monitors to meet the demands of more strict professional production environments.Controls and ConnectivityROOM CONTROL allows you to attenuate the unnatural, exaggerated low-end that can often occur when speakers are placed next to walls, while HIGH TRIM allows for more flexible control of high frequency response. For inputs, HS full-range speakers can accommodate a wide range of balanced and unbalanced sources such as mixers, keyboards and audio interfaces with XLR and TRS phone jacks. With the HS8S subwoofer, HIGH CUT control sets the cutoff frequency of subwoofer output high-frequency attenuation from 80Hz to 120Hz, while PHASE switch adjusts the phase of the subwoofer output. Th
