What customers say
Mastering and mixing engineers highly value the Amphion BaseTwo25 for its uncompromising low-frequency accuracy and phase coherence. Users emphasize its speed and definition, noting it functions as a true bass extension rather than a typical subwoofer. The system excels at revealing subtle low-end issues that other subwoofers often obscure. Integration with Amphion monitors is seamless, creating a full-spectrum environment where the crossover is undetectable. This results in mixes that translate exceptionally well. While the investment is significant, professionals consider the BaseTwo25 an essential tool justifying its cost through improved workflow and superior mix quality. It sets a new benchmark for low-frequency monitoring precision.
Know before you buy
While the BaseTwo25 is designed to integrate seamlessly with most two-way monitors, it is specifically optimized to work with Amphion's own monitor lineup. If you are using third-party speakers, ensure your setup can accommodate the active crossover integration provided by the BaseAmp1200.
The BaseAmp1200 is a dedicated power amplifier that connects to your monitors via 2-pole Neutrik Speakon connectors. It acts as the engine for the system, handling the active crossover management to ensure a smooth transition between your monitors and the subwoofers.
Passive radiators allow the BaseTwo25 to achieve deep, accurate bass extension without the air turbulence or port noise often associated with traditional bass-reflex designs. This results in a tighter, more musical low-end response that maintains clarity even at high volumes.
The system features a selectable 4-step crossover module that allows you to choose between 40, 60, 80, or 100 Hz. This flexibility lets you dial in the exact frequency point where your monitors hand off the low-end duties to the subwoofers, helping you achieve better phase coherence in your listening environment.
The BaseTwo25 is a high-output system capable of 127dB SPL, making it well-suited for professional environments. While it provides immense power, its design focuses on precision and phase coherence, meaning it can perform effectively in medium-to-large rooms where accurate, full-range monitoring is required.
The BaseTwo25 is engineered primarily for professional studio environments where critical listening and high-resolution accuracy are paramount. Its design prioritizes the phase-accurate, full-range performance needed for professional mixing and mastering applications.
