The FlexBase25 is engineered to solve the common translation issues associated with mono subwoofers. By maintaining stereo integrity all the way down to 20 Hz, it ensures that you have a clear view of the spatial information across the entire frequency spectrum. The system consists of a massive 110 lb (50 kg) sealed cabinet and a dedicated FlexAmp1200 rack unit, providing a staggering 1,400W of total power to ensure your low-end is both powerful and pristine.
Product Description
Surgical Control and Versatility:
The "Flex" in FlexBase25 refers to its incredible adaptability. The front panel of the FlexAmp1200 features three main dials that allow you to sculpt your sound in real-time:
Crossover Frequency (35–260 Hz): Choose exactly where your main monitors stop and the FlexBase begins. High settings clean up the midrange of smaller monitors, while lower settings add a subtle "missing octave."
Subwoofer Level: Easily adjust the bass energy to match your room's acoustics or the specific vibe of a project.
Mono-Stereo Spread: A unique control that lets you decide the width of your sub-bass—from a focused mono center to a wide, immersive stereo image.
Acoustic Excellence and Power:
Dual 10" Aluminum Drivers: The cabinet houses two opposite-facing, long-throw 10-inch drivers. This sealed-box design ensures a fast, dry, and high-impulse response, eliminating the "smearing" often found in ported subs.
Abundant Headroom: Driven by 2x700W (RMS into 4Ω), the system delivers a maximum 117 dB SPL. This massive power ensures that transients are reproduced with zero compression, providing the headroom needed for modern, bass-heavy productions.
Seamless Integration: The system lives inline between your interface and your monitors. With a single click of the bypass switch (or optional footswitch), you can return your monitors to full-range for a quick reality check.
Finnish Craftsmanship:
Handmade in Finland, the FlexBase25 is built with the same meticulous attention to phase accuracy as Amphion's flagship monitors. Its compact, vertical "monolith" design allows it to sit on the center line between your monitors, saving floor space while providing a rock-solid sonic foundation.
