The Final Audio DX6000 marks the Japanese manufacturer’s inaugural entry in a new line of open over-ear headphones. Instead of relying on exaggerated claims, Final Audio captivates with distinctive design elements that provide both quantifiable and perceptible advantages. The designers assert that the Final DX6000 effectively resolves the shortcomings that have plagued numerous high-end dynamic models in the past.
Final DX6000
At the heart of the DX6000 is a 50-millimeter dynamic driver with a wafer-thin, pure magnesium diaphragm. This metal is about a third lighter than aluminum, yet is very stiff and boasts favorable internal damping properties. In practice, this promises reduced partial vibrations and therefore less distortion. This is a characteristic typically offered only by very expensive beryllium or heavy sandwich diaphragms in loudspeakers. The finish is delicate: Final relies on oxidation and targeted folding to ensure stability and durability. The specified impedance is 47 ohms, and the DX6000 has a sensitivity of 83 dB/mW. It weighs 363 grams, without cable.
Another detail is the monolithic injection-molded frame surrounding the diaphragm. Eliminating the need for adhesive reduces the moving weight, allowing the diaphragm to move almost perfectly like a piston. The voice coil itself is made of a lightweight aluminum alloy and is connected via air wiring, i.e., directly without rigid conductors. This lowers the resonant frequency and improves the impulse response in the bass. Lightweight diaphragm systems tend to have peaks in the high frequencies. Final uses no additional coil or damping weight here, but integrates a passive network into the signal path to keep the higher frequencies linear.
While many closed-back designs generate bass through the volume of the earcups, the DX6000 relies on the bass capabilities of the driver itself. The enclosure is open, with the front and back blending almost seamlessly. This creates a more realistic spatial effect and minimizes resonance within the earcup. The DX6000 combines rare materials, a largely glue-free mechanism, and an open-back design. Those already using open-back headphones will particularly appreciate the combination of deep, uncolored bass and an airy soundstage.
