3.5-Way Sealed MTM Loudspeaker with Coaxial Mid / High

Echo is a large-format loudspeaker designed for presence, control, and spatial precision. Built around a sealed MTM architecture, it combines dual 10" low-frequency drivers with a coaxial mid / high assembly to create a coherent, high-efficiency system that scales effortlessly from intimate listening to room-filling playback.

At the center of Echo is a coaxial mid / high driver, allowing midrange and treble to radiate from the same acoustic point. This point-source behavior locks vocals and instruments firmly in space, while the symmetrical MTM layout stabilizes vertical dispersion and preserves wide, even horizontal coverage.

The sealed enclosure is tuned for speed and control rather than excess bloom. Bass remains tight and articulate, integrates cleanly with subwoofers, and retains its character across a wide range of listening levels.

The front baffle is 3D printed as a single, precision-formed structure, shaping the acoustic loading and driver geometry to ensure consistent crossover behavior and controlled diffraction. Each baffle can be produced in custom finishes and colors, allowing Echo to remain visually as considered as it is acoustically exact.
