BaseTwo25 system

BaseTwo25 is a bass extension system, which transforms a 2-way monitor into a 3-way full range system. The system consists of a 2U crossover/amplifier unit and two identical, double-sided extenders. Each side of the extender has a long-throw 10" woofer at the top and a matching passive radiator below. For the best possible integration, extenders also act as a monitor stand. Due to the benefits of force cancellation, the extenders remain stable even during the most demanding bass tracks.

BaseTwo25 has four possible crossover settings: 40 Hz, 60 Hz, 80 Hz, and 100 Hz.

For optimal integration BaseTwo25 creates an additional crossover point and transforms your 2-way monitor into a cohesive 3-way full range system. BaseTwo25 improves power-handling and reduces the intermodulation distortion of the mid-woofers. The best crossover-setting depends on the monitor and listening level.

The system has a by-pass option for those moments when you want to use your monitors for a narrower midrange view. The by-pass is selectable via foot-switch or a push button on the front plate of the BaseAmp. BaseTwo25 works with all Amphion products, as well as with monitors that have sufficient speed and resolution in the critical upper-bass/lower-mid frequencies.

STEREO TO THE LOWEST OCTAVE:

Amphion's introduced their first Base Extension system in 2015. The concept of keeping stereo information all the way down has become widely adopted since.

SEAMLESS INTEGRATION:

Designed to work seamlessly with all monitor sizes. System can even be paired with a smaller model for an ultra-fast, easy to adjust small room full-range system.

ELEVATE YOUR MONITORS:

As the bass frequencies are transferred to the Base system, the midrange clarity and power-handling of the paired monitors are greatly enhanced.

INDUSTRY-DEFINING CLARITY:

Force-cancelling driver configuration and highest quality components lead into industry-defining clarity, control, and low frequency detail.

SIMPLE SETUP:

Always placed under the monitors. Fixed placement and physical proximity between the monitor and bass extender ensure perfect integration.

2-WAY, 3-WAY OR AMPHION WAY:

Simplicity of a 2-way monitor or the power handling of a 3-way design The system can easily switch between both with a push of a button or foot switch.
