Overview
ULTIMEA built the Skywave Dual as a soundbar based cinema system with dual wireless subwoofers and four wireless surround speakers. A dual band wireless link holds all channels in sync, and Atmos and DTS:X height effects come from dedicated up-firing channels.
Receiver class channel count and deep bass without running speaker wire across the room is the core draw for living room theaters. Wireless here means no audio cables, not no power cables.
Who it's for
Dedicated movie rooms and large living rooms suit the channel count and dual subs. Small spaces and anyone sensitive to neighbors will find it too much.
Pros and cons
- Dual subwoofers with deep extension
- Six height channels for Atmos
- No speaker wiring between units
- Per-speaker level control
- Every speaker needs a power outlet
- Large system for small rooms
- Heavy shipping weight
Performance notes
Immersion comes from object based decoding that steers sound to the height and surround speakers, so placement and level matching matter. Individual surround level control compensates for uneven seating. Two subwoofers spread bass more evenly across the room.
