The hd MP12N is a full-range speaker that has been specifically designed and optimized to be a true multi-purpose speaker for fixed installations and mobile applications. The innovative acoustic design achieves true linear response – not just in terms of flat frequency response, but also in the dynamic range and all other acoustic parameters. A precisely developed and elaborate crossover ensures outstanding performance of the compact speakers. The housings of the hd MP12N are equipped with the most powerful neodymium woofers with 600 W / 2400 W (RMS / Peak). The new neodymium high-frequency driver is coupled to a large, rotatable horn with a particularly low crossover frequency, which guarantees a high directivity and controlled dispersion in the important voice range. Different horn versions allow horizontal and vertical radiation characteristics of either 90° x 60° or 60° x 40°.

The acoustic and mechanical design guarantees a coherent, trouble-free and balanced reproduction of different music styles and sounds even without additional DSP. Harmonic Design MPs can be easily connected to any standard power amplifier. Noteworthy is the unique reproduction of transients and the tonal depth and clarity of effects. The SuperVented housing design combined with an extremely durable voice coil paired with the neodymium magnet geometry assembly of the latest technology makes the hd MP12N a dynamic full range speaker. They are seamlessly integrated into the Harmonic Design system philosophy by simply adding multiple hd Sub-Series or hd P-Series subwoofers or operating up to four hd MPs on one channel of the Harmonic Design system amplifiers.

The rounded, asymmetrical housing is made of high-strength multiplex wood and is provided with a weatherproof polyurethane coating. The integrated 35 mm tripod adapter allows use on a tripod as a front system and is complemented by two practical monitor angles of 32° and 45° for discreet and high volume monitor applications. Three Speakon connectors – two on the back, one on the bottom – ensure invisible and kink-free wiring. A powder-coated steel grille with acoustic foam on the inside protects the speaker components. An ergonomic handle for transport is placed on top. Extensive accessories and twelve integrated M8 mounting points provide maximum flexibility for daily changing sound reinforcement tasks. In addition to the extremely robust polyurethane coating in black, RAL colors are available.
