Improving 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. Yamaha engineers have optimized the HS powered monitor and subwoofer monitor system for a variety of music production environments.
The ultra-responsive HS8S (8" cone) powered subwoofer employs large, carefully selected magnets to produce low distortion sound with a well-defined bottom end at all output levels. Two balanced XLR and two balanced 1/4" phone jacks are provided for advanced connectivity and customization. All of the woofer’s components, including the woofer ring and basket, further contribute to the stunning bass and clear, accurate mids.
Additionally, the new HS Series cabinets offer low resonance enclosure designs constructed from a dense, resilient MDF for a damped acoustic response that is perfectly suited for reference monitors. Each monitor and subwoofer is also equipped with a unique high performance amp unit, perfectly paired with each transducer. The coupled amp unit ensures that each HS Series speaker delivers high-resolution sound with exceptionally flat response across the spectrum.
Each monitor speaker employs leading edge noise reduction technology, controlling and reducing the vortex at either end of the speaker port that can generate air vibrations inside and cause unwanted noise in many studio monitors. To combat this, Yamaha adopted advanced noise reduction technology when designing the ports.
