Pro-Ject Audio Systems has expanded its streaming portfolio with two new products aimed at simplifying integration between traditional hi-fi systems and modern networked audio: the Stream Box E and Wireless Box E.
Both devices are built on WiiM OS, positioning them within a growing multi-room ecosystem that Pro-Ject has been developing alongside its core analogue offering.
The Stream Box E is designed as a compact network streamer and digital preamp, intended to add streaming capability to existing systems without requiring wholesale upgrades. It supports services including Spotify Connect, Tidal Connect and Qobuz, and can be deployed in several configurations; as an add-on to a legacy amplifier, as the control centre in a simple separates system, or paired directly with active speakers.
Alongside its digital functionality, the unit includes an analogue input, allowing sources such as turntables to be distributed across compatible devices within the Pro-Ject ecosystem.
The Wireless Box E takes a different approach, targeting speaker-level integration. The device acts as a wireless receiver for passive loudspeakers, attaching directly to speaker terminals to eliminate the need for traditional cable runs. Each speaker requires its own unit and a mains power connection, with optional extension cabling available where direct mounting is not practical.
In use, the Wireless Box E is intended for scenarios where running speaker cable is either undesirable or impractical, including multi-room expansion and flexible speaker placement. While optimised for Pro-Ject’s own speaker range, it can also be used with third-party passive loudspeakers with compatible terminal layouts.
Both products form part of a wider platform that includes the Uni Box S3, introduced in 2025, allowing multiple devices to be linked across a home network. The system supports both independent playback and synchronised multi-room audio, including the distribution of analogue sources.
