Yu4 Passive

Yu4 Passive 2nd Gen is a passive two-way bookshelf speaker pair. Each cabinet combines a 1-inch silk dome tweeter with a 4-inch abaca-reinforced paper cone woofer, covering 60 Hz to 22 kHz. Power handling is 80 W peak (55 W RMS) per speaker at a 4 ohm impedance.

The enclosure is rigid MDF with a laminate finish, intended to limit unwanted vibration, and the drivers have a silicone trim for a flush front. A threaded 1/4"-20 hole in the base allows mounting on compatible stands, and the small footprint makes the speakers easy to place on a desk, a console or as part of a surround system.

There are no built-in inputs for sources or wireless connections. An external amplifier that works with 4-ohm speakers is required, so the system's sources and features are determined by the amp or receiver you choose. The box includes the pair, eight self-adhesive rubber feet and a quick start guide.
