​We've prepared this spreadsheet to help installers match pre-existing ceiling cut-outs with compatible JBL In-Ceiling speaker options for retro-fitting.  Utilize the color guide in the top right to quickly determine which JBL options are viable, then reference the power, frequency, and coverage specs to ensure the best option is chosen for the install.  Download a copy of the spreadsheet from the margin for quick reference or offline use.

All hyperlinks are disabled in the above image, but functional in the file available for download.  As always, feel free to reach out to Technical Support with any questions at 1-844-776-4899, option 3
