Pro-Ject Wireless Box E Plug-in Streaming Amplifier, Black Overview
The Pro-Ject Wireless Box E is designed for turning passive speakers into a compact wireless streaming system without adding a traditional amplifier. It connects directly to the speaker terminals of compatible Pro-Ject loudspeakers, giving each speaker built-in amplification and network streaming in a neat, space-saving form. For speakers from other brands, the optional Connect it LS Flex cable adds extra setup flexibility.
Streaming is powered by WiiM OS, giving you access to music services through the Pro-Ject Home App, alongside dual-band Wi-Fi for reliable everyday listening. Pro-Ject True Wireless Receiving also lets the Wireless Box E receive audio from compatible products such as the Uni Box S3, Stream Box E, and latest-generation Pro-Ject streamers. This makes it a practical choice for multiroom systems, wireless vinyl playback from the T2 W, or simply modernising an existing pair of passive speakers with less cabling and fewer boxes.
