- Dual Sound Modes: A physical rear switch alters the internal DSP curve between DJ Mode (punchy, energetic bass kicks) and Production Mode (flat, accurate reference response).
- Front-Loaded Bass Reflex: Custom 4-inch fiberglass woofers utilize grooved air ducts to push out tight low-end audio, even when positioned directly against a wall.
