Martin-audio C8.1T 天花喇叭

The C8.1T has been specifically designed for higher ceilings where its high SPL capability and controlled 90° dispersion enable it to provide excellent intelligibility in more reverberant rooms. It features an 8" (200mm) unit with a carbon fibre loaded, polypropylene cone and a 1" (25mm) horn-loaded dome tweeter mounted side-by-side for optimum dispersion and smooth response off-axis. The enclosure is ported to extend the low frequency performance and the 5-point mounting system ensures that installation is fast and secure. Input and link terminals make paralleling units a simple operation and a steel cover plate protects the input connector against fire.

These products comply with UL2043 Fire Tests for Heat & Visible Smoke Release for Discrete Products and their Accessories Installed in Air Handling Spaces.
