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.
