500W RMS High-Performance Mono Amplifier

The Infinity Primus 50011A is a compact, high-efficiency Class D mono subwoofer amplifier built to provide heavy-hitting bass in space-constrained installations. This amplifier is part of the second-generation Primus series, designed to offer reliable performance and advanced tuning options at an accessible price point. Its small footprint allows for versatile mounting under seats or in tight storage compartments without the heat issues typically associated with larger Class AB amplifiers.

It features a sophisticated Bass EQ section that allows you to adjust not just the boost level (0-12dB), but also the center frequency (30Hz-100Hz) and the "Q" factor (bandwidth), providing surgical control over the subwoofer's impact. Additionally, it includes an integrated phase switch and a variable low-pass filter, making it easy to blend the subwoofer perfectly with the rest of your system.
