Yamaha HS8S 150W 8-Inch Active Studio Subwoofer
The Yamaha HS8S adds dedicated bass monitoring to a studio speaker system. Consider it when your production work requires closer assessment of low-frequency content, taking your room acoustics and available placement options into account.
Dedicated Low-Frequency Amplification
An 8-inch cone driver is powered by a built-in 150W amplifier designed for low frequencies. The bass-reflex cabinet provides a compact subwoofer format for a studio monitoring system.
Integrate Your Monitors
Left and right inputs accept signals from suitable studio equipment, with XLR outputs feeding your powered monitors. This provides a practical connection path from your audio source through the subwoofer to your main speakers.
Adjust the Transition Between Speakers
HIGH CUT, LOW CUT, PHASE and LEVEL controls help integrate the subwoofer with your monitors. Spend time assessing placement and settings so bass supports your monitoring decisions without dominating the listening position.
Package information: This listing is for one HS8S subwoofer. Studio monitors and audio cables are sold separately.
Who Should Choose the Yamaha HS8S?
- Music producers: Consider it when assessing bass instruments, kick drums and other low-frequency content.
- HS monitor owners: Plan a subwoofer addition around your existing listening setup.
- Mix engineers: Add another monitoring perspective when your work requires deeper bass assessment.
- Content creators: Consider your low-frequency monitoring needs for music and sound design.
Assess room acoustics, placement and calibration before adding a subwoofer. A carefully balanced system is more useful than simply increasing bass level.

Can I use it with Yamaha HS5, HS7 or HS8 monitors?
Yes. Yamaha provides connection guidance for these monitors in the HS-series owner's manual.
How does it connect in a stereo system?
