Description

For those who demand precision and depth in their audio production, the PSI Audio Sub A225-M is an exceptional choice. This active subwoofer is engineered to expand the capabilities of your studio monitors, offering a frequency response of 24 to 100 Hz that ensures every bass note is delivered with clarity and power. Its Adaptive Output Impedance (AOI) Technology provides ideal dampening by detecting and counterbalancing membrane and coil movements, making it a standout feature for serious audiophiles.

Built with a Class-G amplifier, the Sub A225-M delivers 200 watts of RMS power to its twin 8-inch woofers, creating a robust soundstage without compromising on fidelity. The subwoofer's double-box MDF enclosure is designed with a built-in anti-resonance system, ensuring uncolored sound reproduction. This is further enhanced by the amplifier unit being acoustically uncoupled, eliminating unwanted artifacts.

The Sub A225-M is not just about power; it’s about adaptability. With real balanced XLR inputs and outputs, it integrates seamlessly with both stereo and multi-channel setups. The rear panel features controls for level/input sensitivity and low-frequency roll-off, allowing you to tailor the sound to your room's acoustics. Designed with precision in mind, it also includes innovative Compensated Phase Response (CPR) Technology for minimal group delay, ensuring phase accuracy across all frequencies.
