SALT LAKE CITY, UTAH – We are thrilled to unveil the X4 Ultra, an extraordinary speaker that transcends cost limitations and elevates your listening experience to new heights. Building upon the success of the X4 Premium, this remarkable upgrade incorporates cutting-edge features that set new standards in audio fidelity and stability, delivering a truly immersive and captivating auditory experience.

Enhanced Crossover System
The X4 Ultra introduces an enhanced crossover system that redefines audio fidelity. By carefully selecting top-tier components, we have minimized distortion and prioritized transparency, ensuring the most revealing detail and musicality possible. The inclusion of copper foil inductors and oil-impregnated film capacitors achieves a remarkable balance, resulting in precise imaging, a spacious soundstage, and an immersive listening experience that brings the music to life in all its glory.

Sturdy Aluminum Base
To provide superior stability and support for the X4 Ultra, we have reengineered the aluminum base. This redesigned base accommodates the larger crossover and offers robust reinforcement. Additionally, the X4 Ultra features support for vibration isolating IsoAcoustics Gaia feet. The four-point contact system of Gaia feet not only acoustically isolates the speaker from the floor but also effectively eliminates unwanted harmonics, ensuring a cleaner midrange and tighter bass response. With the X4 Ultra, you can indulge in the purest form of audio bliss.

Our relentless pursuit of audio perfection led us to create the X4 Ultra—an upgrade that defies limitations and delivers an unparalleled listening experience, "We have carefully crafted every detail, from the enhanced crossover system to the sturdier aluminum base. The result is a speaker that not only satisfies the most discerning audiophiles but also pushes the boundaries of audio excellence."
