Biamp Desono SPA-TR400 Trim Ring (10-Pack)

The Biamp Desono SPA-TR400 is a finish trim ring for the Desono DX-IC6 and C-IC6 ceiling loudspeakers (black and white, including the DX-IC6-B), sold in a 10-pack.

It covers the mounting cutout around the loudspeaker for a clean finished edge once installed. This is the current DX-series part number for the ring previously sold as D6-CATR-10PK, per Biamp's DX-series rebrand cross-reference.
