Sorry it’s me again  - no, the Beosound Core can’t connect to speakers wirelessly either. It performs the same function as the Beoconnect Core - essentially that of a streamer and preamp, but it runs on an older platform with fewer features and minus the HDMI, although it does have an optical output which is useful, unlike the Beoconnect Core. I’m pretty sure it’s only the TVs that have ever been able to connect to other speakers wirelessly - no Beosound ‘system’ ever has. The Transmitter 1 is a standalone Wisa transmitter box that you can connect a stereo or 5.1 audio system (B&O or otherwise) to and then connect to 2/2.1/5.1 WISA speakers wirelessly. Most recently the Beosound Theater can connect to other WISA speakers wirelessly. I think those are the only B&O options.
