LNGR 1-2-CX is the active smart-speaker project in the LNGR SPKR family. The enclosure remains a 320 mm square front with 300 mm depth and passive radiators on the sides. The interface stays deliberately minimal: a round volume display, one encoder and two buttons for AirPlay and Bluetooth.
The current streaming computer is a Raspberry Pi 3A with a 64 GB card. AirPlay and Bluetooth are core functions; Spotify Connect via librespot remains on the software roadmap. The 8-inch coaxial driver will only be frozen into the P1 CNC geometry after physical component verification.
P0.2 remains available — as an archive
Do not use as the current manufacturing release.
The P0.2 files dated 24 August 2026 document an earlier iteration with different hardware assumptions. They remain downloadable for traceability but are explicitly not P1.
