Thanks Pano I had some open baffle built for the C1802, but we were waiting for the woofer (I ordered W18, they sent F18!) that was missing but I'll try them first without since vendor cannot figure out a solution. Hope now it will only be a question of weeks (after ordering everything in December...). Will post pics when it's hooked up (to a Wiim Amp as I was planing to use the active filtering the app offers).
Please do! It sounds like a project that is worth its own thread. Always fun to see amd learn from people’s OB builds.
