Sound that Stays True to the Original The HS-series continue the design philosophy and expertise of previous Yamaha studio monitors. In our thorough pursuit of the best products, our speakers are constructed with carefully selected parts such as powerful class D amplifiers, highly durable MDF cabinets, woofers, and soft dome tweeters that deliver unique sound. Despite their small size, it remains true to its source. It also features a unique Twisted Flare Port technology that reduces air turbulence within the bass reflex port, resulting in clear and accurate bass. This is the secret behind how the HS-series deliver superior resolution, sound image and depth with consistent frequency response across all bandwidths without distorting the original sound. Tailor the Sound to your Environment The sound emitted from speakers may be affected by the environment. The back panel of the HS3 is equipped with ROOM CONTROL and HIGH TRIM functions that can be adjusted to achieve the ideal sound for your environment, such as reducing unnecessary and exaggerated bass that often occurs when speakers are placed next to a wall. Inputs and Controls For any use The rear panels of the HS3 feature a combination of XLR/TRS phone, RCA, and stereo mini connectors allow for connecting a variety of professional and consumer equipment, including computers, audio interfaces, audio mixers, and electric instruments. The most commonly used features are located on the front for easy access, including the power button, volume control, and headphone connector. Compact and Portable The compact size of the HS-Series is made possible by a highly efficient Class D amplifier. By using one amplifier for two speakers, we are able to reduce the weight of the speakers and simplify cable connections. It takes up very little space even in a small bedroom studio and is easily portable for travel.
