【Cautions for using electrical products】
When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions.
Since the plug type is Japan type(A or B type), please check the voltage and use a transformer.
Please note that a transformer is different from a conversion adapter.
We are not responsible for malfunctions caused by use without a transformer.
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Bass reflex type with 8 inch woofer for LF
Covers playback frequency band 22Hz – 160Hz
Equipped with a 150W high-output power amplifier designed specifically for bass frequencies.
Dimensions: 300W x 350H x 389Dmm, weight: 12.5kg
Power consumption: 70W
[Features & Recommended Points]
- Covers ultra-low frequencies: Equipped with an 8-inch (approx. 203 mm) cone woofer, it achieves a frequency range down to 22 Hz at -10 dB. Captures the “rumble” and air of bass, kick, and sub-bass sounds.
- Built-in 150W (dynamic output) power amplifier: A high-output amplifier specifically designed for low frequencies allows for clear and powerful bass even at higher volumes, with minimal distortion.
- Extensive connectivity and adjustment functions:
Inputs: Balanced XLR ×2, TRS (¼″) ×2.
Outputs: Balanced XLR L/R output + EXT SUB output.
Adjustment functions: LEVEL control / PHASE switch (NORM/REV) / HIGH CUT switch (~80–120 Hz) / LOW CUT switch (80–120 Hz). Allows phase and crossover adjustments with monitor speakers.
- Designed for high-precision monitoring environments:
Cabinet made of high-density MDF to suppress resonance.
Low-resonance design and port noise reduction technology minimize “muddy” or “boomy” impressions at low frequencies, providing clear, well-defined bass.
- Versatile use for studio and home: Suitable not only for professional recording and mixing environments but also for home studios, hi-fi listening, gaming, and enhancing movie sound.
- Compact size & flexible placement: Dimensions of W300 × H350 × D389 mm / weight approx. 12.5 kg make it easy to place. Can be used on the floor, on stands, or in corners for high layout flexibility.
[Highly recommended for:]
- Those producing music, mixing, or mastering: Enables precise understanding of low-frequency behavior, allowing detailed checking of sub-bass and kick decay that might be hard to detect with speakers alone.
- Home theater or gaming enthusiasts seeking “powerful” bass: Enhances the impact of movie explosions or game bass, delivering both sound pressure and tactile satisfaction.
- High-end audio users seeking clear, faithful reproduction: The HS series design emphasizes not just “more bass,” but bass that preserves localization, clarity, and detail.
- Existing users of YAMAHA “HS Series” (e.g., HS5 / HS7 / HS8): Using it as a subwoofer in the same series ensures sound field consistency and visual harmony.
[Summary:]
The YAMAHA HS8S is not just a speaker to “boost bass,” but a professional-grade active subwoofer designed to expand low frequencies while maintaining accurate sound. Its 22 Hz ultra-low frequency reproduction, 150W dedicated amplifier, phase and cutoff adjustment functions, and high-level cabinet design that minimizes resonance and noise combine to deliver a truly immersive low-frequency experience for music, movies, and games. From home studios to professional studios, it provides a solid foundation for users who want faithful reproduction of audio details. Whether for production or listening, it elevates the sound experience to the next level.
