A High-End Series of Recessed Ceiling Speakers for Architectural Integration
With this new series of recessed ceiling speakers, Martin aims for elegant integration in places where aesthetics matter as much as sound quality. The C115 fits this "premium" logic: it visually disappears while ensuring even coverage and clear reproduction for background music as well as announcements. Its switchable low impedance / 100 volts design allows integration both in classic installations and multi-zone sound reinforcement projects.
For Which Installations and Users Is the Martin C115 Intended?
The Martin C115 is aimed at installers, integrators, and operators seeking a reliable, versatile, and easy-to-deploy ceiling speaker: retail stores, restaurants, hotels, reception areas, offices, meeting rooms, corridors, cultural venues, as well as challenging areas such as humid environments. Thanks to its very good intelligibility at low levels, it is particularly suitable for transit areas where a homogeneous background sound is desired without any sense of harshness, while maintaining excellent speech clarity.
