The Amphion BaseTwo25 Bass Extension System is the ultimate upgrade for Amphion studio monitor users, turning a trusted 2-way setup into a powerful full-range 3-way system. Experience deeper, more accurate low end while gaining improved clarity and confidence in every mix
The Amphion BaseTwo25 is both an extension and an enhancement, designed to sit beneath your existing Amphion studio monitors and add robust, accurate bass without compromising the midrange transparency you rely on. This system includes a pair of double-sided bass extenders, each housing a long-throw 10" aluminium woofer paired with a matching passive radiator in a force-canceling configuration. It is powered by a rack-mountable BaseAmp1200, which offers selectable crossovers, volume control, and a convenient bypass function.
At Front End Audio, we recognize how important it is for engineers and producers to trust what they hear across the full frequency spectrum. The BaseTwo25 delivers the kind of low-end accuracy and headroom that lets your Amphion monitors perform at their absolute best, giving you a clearer picture of your mix and the confidence that it will translate outside the studio.
