The Monitor Audio IWA-250 is a high-efficiency Class D amplifier specifically designed to power in-wall subwoofers like the IWS-10. With 250 watts at 4 ohms, built-in DSP processing, and a 1U rack-mountable chassis, it offers a discreet yet powerful solution for home cinema systems and custom audio installations.
Tailored for high-performance integration, the IWA-250 includes three DSP EQ modes (Music, Movie, Impact), adjustable crossover (40–120 Hz), and phase control for precise bass management in any room. It can drive one or two subwoofers, and its efficient switched-mode power supply ensures cool, silent operation, even in closed rack environments.
With auto signal sensing, 12V trigger input, balanced and unbalanced inputs, and low standby power (<0.5W), the IWA-250 seamlessly fits into modern smart home systems or commercial AV setups.
