Compact and versatile, the second-generation Yu4 brings clear, powerful sound to the spaces where you listen most. Re-engineered drivers paired with advanced DSP tuning deliver greater clarity, a more balanced sound signature, and unexpected depth for its size. Whether you’re spinning vinyl, streaming new tracks, or jumping into a game, Yu4 integrates seamlessly with your entire setup. 
A powerful Class-D amplifier platform delivers 110 W RMS (160 W Peak) of total output. 1” silk dome tweeters provide clear, responsive highs while the 4” abaca-reinforced paper cone woofer fills your room with smooth, controlled bass down to 60 Hz. Modernized connectivity includes Bluetooth® 5.3, USB-C audio playback, and an analog input with a selectable phono preamp. A timeless silhouette with elevated detailing, Yu4 complements any modern space with approachable, intuitive, high-fidelity performance. 

PERFORMANCE THAT ADAPTS - Built to perform, designed to adapt — Yu4 prioritizes acoustic performance while offering versatile connectivity for today’s sources and tomorrow’s add-ons. With USB-C power, analog and digital inputs, plus subwoofer output, it’s easy to connect a turntable, TV, computer, subwoofer, Wi-Fi transmitter, or future audio accessories, ensuring your speakers remain useful and adaptable for years to come.

REFINED ACOUSTICS, MORE POWER - Re-engineered drivers, custom DSP tuning, and a redesigned amplifier platform work together to deliver a balanced presentation with improved clarity, deeper bass extension down to 60 Hz, and 30% more output power. The result is room-filling sound that remains composed and natural at any volume.

SMOOTH & NATURAL SOUND - Designed for all the ways you listen. A 1" silk dome tweeter delivers detailed, fatigue-free highs, while the 4" abaca-paper woofer provides controlled bass and natural midrange reproduction. Together, they create a balanced, warm sound signature that's enjoyable across music, movies, and everyday listening.

INTELLIGENT CONNECTIVITY & SUB INTEGRATION - Ready for modern systems — Switch effortlessly between analog and digital sources with Bluetooth 5.3, USB-C, 3.5mm aux, optical, and an RCA input with integrated phono preamp. When a subwoofer is connected, Yu4 automatically applies an 80 Hz high-pass filter, reducing distortion and allowing the speakers to focus on midrange and high-frequency detail for cleaner, more dynamic sound.

THOUGHTFUL, DURABLE DESIGN - Crafted with attention to every detail — Rigid MDF cabinets minimize unwanted resonance, while seamless silicone trim rings create a clean, refined appearance and help reduce diffraction around the drivers. Integrated mounting points and intuitive on-speaker controls make Yu4 equally at home on a desk, shelf, stand, or media console.

INTUITIVE REMOTE CONTROL - Complete control from anywhere in the room — The included remote features tactile silicone buttons for effortless operation, with dedicated controls for volume, playback, input selection, and bass and treble adjustment. Fine-tune your listening experience without leaving your seat.
