Zu Audio has been making loudspeakers for 22 years and we’ve been fans and customers for over a decade. Sean Casey has never played by the rules in the high-end audio world and that’s perfectly fine on our book. The pandemic has not been kind to our friends in Utah; supply chain issues have led to long delays and the end of the Omen Dirty Weekend project as well. The new Zu Union 6 lineup has been unveiled and we’re very intrigued.
The Zu Union 6 Series
Zu Audio has decided to revamp its speaker product line. Their new Zu Union 6 Series are designed to replace several recent models: Omen Dirty Weekend, Omen 2, Soul Supreme, Omen Bookshelf, Omen Center Channel, and Zu Cube.
Making such a move is a big undertaking. Here is what Zu Audio had in mind:
- Raise resolution, transparency, and tone.
- Make each speaker unfussy with respect to room placement and connected gear.
- Remove 12 ohms and 16-ohm models and go with the mass market 8-ohm standard.
- Eliminate the Zu set-up task of finding the right room floor-to-speaker gap.
The Union 6 is described by Zu Audio as a “full-spectrum, highly resolving and robust floor-standing loudspeaker”.
