Know before you buy
The IWA-250 is specifically engineered and optimized for the IWS-10 in-wall subwoofer. While it may technically drive other passive subwoofers, the DSP settings and limiters are calibrated for the IWS-10, so performance cannot be guaranteed with third-party drivers.
Yes, the IWA-250 is designed to drive up to two IWS-10 subwoofers simultaneously. This makes it an ideal solution for larger rooms where you need dual-subwoofer coverage for more uniform bass distribution.
While the Class D design is highly efficient and runs cooler than traditional amplifiers, it is still recommended to provide adequate airflow around the unit. Ensure your rack setup allows for proper ventilation to maintain long-term reliability.
The built-in DSP provides advanced limiting and equalization that protects your subwoofers from being overdriven. It ensures that the amplifier delivers clean, controlled bass performance even at higher volumes, preventing distortion and potential damage to the drivers.
The IWA-250 is ErP certified and features an ultra-low standby power consumption of less than 0.5 watts. This makes it an energy-efficient choice for custom installations that remain powered on or in standby mode for extended periods.
