O&B SSM9X 9-Channel Amplifier
SSM 9X
The SSM 9X is our flagship 9-channel power amplifier, meticulously engineered to deliver exceptional clarity, headroom, and control for high-performance home theater systems. It delivers a robust 400 watts per channel at 4Ω for the front Left, Center, and Right (LCR) channels—ensuring dynamic, distortion-free reproduction where it matters most. The remaining four surround channels are powered at a solid 150 watts per channel at 4Ω, striking the perfect balance between immersive surround detail and overall system efficiency.
