Surface mount loudspeakers Soft dome tweeter The newly developed 1-inch soft dome tweeter is the perfect component to deliver short-throw high-definition high frequencies. Rich, punchy bass with low distortion Using the Kelton method^2 the CM-510ST filters out unwanted mid- and high-range frequencies and includes our newly developed Vortex Bass Accelerator technology to deliver pure, smooth bass with a quick response. Newly developed Vortex Bass Accelerator Discover warm bass with the newly developed Vortex Bass Accelerator. The bass-reflex port has been constructed with ribs to ensure that air flows without distortion, to maximise low frequencies and eliminate any unwanted vibrations. Dust and water resistant The CM-S54T, CM-S56T and CM-S58T are IP54 rated. The tough plastic enclosure and included protective terminal cover enable you to cover every inch of space with sound – even in some outdoor areas.^ Original curved enclosure design The CM-S speakers fit neatly into the design of any room thanks to their unique shape. Because they’re neither square nor round, they always look at home – whether they’re mounted on a flat or curved surface. Flexible 8 ohms impedance An impedance of 8 ohms gives high and low impedance options. Deploy two subwoofers on a one-amp channel, dropping the impedance to 4 ohms, and create a perfect solution for a single-amp installation. Compact cabinet with floor and wall mounting options Even though it produces a large, rich bass sound, the technology inside the CM-510ST is packed into a 50-litre box that saves space and fits discreetly into any location. Useful M8 holes make it easy to position the subwoofer wherever you want. Fix it to the floor, wall or ceiling in the location that best suits the installation and sound coverage.
