Amphion BaseOne25 LF Extension System

LF extension to transform Amphion two-way speaker system into a full range time and phase coherent 3-way system


The Amphion BaseOne25 LF Extension System is an extension to transform your Amphion two-way speaker system into a full range 3-way system.
The Amphion BaseOne25 extends your amphion speakers’ frequency range all the way down to 20Hz while also improving dynamic range and greatly reducing distortion. The full system includes two speaker powered by Amphion’s BaseAmp500 crossover and amplifier. The BaseOne25 features a 10” SEAS woofer and 10” Passive radiator in a superb 40”x 7.5”x 14” enclosure designed to rest your near field speakers on. To ensure optimum performance, the BaseOne25 can be used faced inward, outward or forward. The enclosure is made of 35mm Finnish Plywood reinforced by a steel-reinforced power dissipation ring.
The Amphion BaseOne25 is much more than a simple subwoofer, adding perfectly integrated timing and phase coherence. In addition to the extended Low Frequency, the BaseOne25 also increases the power handling of the monitor’s midrange through the transference of frequencies below 100Hz to the 10” woofer using a simple and clever filtering system which lets you easily switch between full range and near-field applications.
The addition of the BaseOne25 system adds full range capabilities with an incredibly accurate 3D soundstage. It’s as if the musicians are playing in the same room as you.
