"Bandwidth Limited" An amplifier designed specifically for subwoofers.

The ARC Audio X2 650.1 is a precisely engineered monoblock amplifier dedicated to subwoofers. By limiting the output band to 10Hz to 230Hz, all power is concentrated on low-frequency signals, achieving clear and powerful deep bass. It boasts a high output of up to 650W at 1Ω load, making it ideal for single or medium-output dual subwoofer configurations.
In addition, by strapping two X2 650.1s together, it can deliver up to 1100W at 4Ω load. It delivers uncompromising deep bass even in limited installation space.
The main unit is a compact chassis made of black steel and features a rotating diamond-cut aluminum badge, combining a high-quality feel with functional beauty. The "installer-first design" allows you to access tuning and connection terminals simply by removing the top panel, making for smart installation.
In addition, it is equipped with a balanced differential input, a feature of the X2 series, achieving high compatibility with the latest genuine audio systems. It is also ideal for OEM upgrades as it can be directly connected to the speaker output without the need for an external converter.
If you want compact, flexible placement and controlled, powerful bass, the X2 650.1 is the ideal power solution for your subwoofer system.
