Extra thin square in-wall in-ceiling 16,5cm (6.5“) coax speakers 8Ω 50W RMS


The MTX iWs65 16.5cm loudspeaker (50W RMS) sounds like a hi-fi speaker, but it stays unobtrusive by fitting into a wall or ceiling and it clearly takes up 100x less space. Our expertise of over 40 years in caraudio has enabled us to offer it characteristics suitable for mounting in an infinite cabinet (without speaker). Its diameter of 16.5cm and its good power handling ensure a pleasant and very musical bass level.
