Elevate Your Monitors to New Heights
The BaseTwo25 is not a traditional subwoofer; it is a specialized extension system designed to improve your existing monitors' performance. By transferring the heavy lifting of low frequencies to the Base system, your main monitors benefit from significantly reduced intermodulation distortion and increased headroom. This results in a cleaner, more detailed midrange and a low-end that is perfectly time and phase-coherent with the rest of the frequency spectrum.
Force-Cancelling Engineering:
Each BaseTwo25 tower features two 10” aluminum woofers at the top and two 10” passive radiators at the bottom, mounted in a back-to-back force-cancelling configuration. This setup cancels out internal vibrations, ensuring that the towers remain stable even during the most demanding bass-heavy tracks. This physical stability translates to industry-defining clarity and control in the lowest octaves.
Precision Control with BaseAmp1200:
Flexible Crossover: The included BaseAmp1200 features a discrete filtering module with a 4-step crossover selection (40, 60, 80, 100 Hz). This allows you to fine-tune the integration between the towers and your main monitors regardless of room size or speaker model.
Instant Comparison: A front-panel bypass button (and a rear footswitch jack) lets you switch instantly between the full-range three-way system and your standard two-way setup. This is a critical tool for checking how your mixes will translate to smaller playback systems.
A Full-Range Monitoring Standard:
With a combined 1,400W of power (700W per channel) and a massive 127 dB dynamic range, the BaseTwo25 handles the extreme transients of modern high-resolution audio with ease. Its vertical design ensures that the bass drivers are in close proximity to the nearfield drivers, maintaining a cohesive point-source image that traditional sub-placements often destroy.
Stereo Extension to 20 Hz: Maintains stereo imaging and spatial cues through the lowest octaves.
Force-Cancelling Design: Opposing drivers and radiators eliminate cabinet vibration for maximum detail.
Midrange Clarity Boost: Offloading bass frequencies reduces distortion in your primary monitors.
BaseAmp1200 Powerhouse: 1,400W total power with high-end Class-A/D hybrid technology.
Variable Crossover & Level: Precise adjustment to match any studio environment or monitor model.
Bypass Functionality: Switch between 2-way and 3-way modes via front button or footswitch.
Handmade in Finland: Built with premium components for professional longevity.
