The new ML 28 subwoofer from France-based Amadeus combines a set of unique acoustical properties with high-timbral precision and extraordinary power handling capability. It’s fitted with dual high-power 18-inch transducers with ventilated voice coils, including high-density neodymium magnets and Double Silicon Spider (DSS) to improve excursion control and linearity. The two drivers are positioned in direct-radiating mode.
The ML 28 is also equipped with low-velocity laminar ports using progressive termination, which optimize the air streams to limit the effects of port compression and extremity diffraction. These developments help result in extraordinary sound pressure level of up to 141 dB with a power handling capacity of 5.600 watts at nominal 4-ohm impedance.
The ML 28 features a proprietary internal reinforcement structure designed to neutralize any standing waves and to suppress energy loss caused by vibrations. This unique construction technique creates an unmatched tonal accuracy for low frequencies, even at high sound pressure levels. Engineers at Amadeus worked to compute these detailed and important internal physical characteristics, built prototypes and tested them, then refined the structure until their sonic expectations were met.\
The ML 28 is designed for use with conventional loudspeakers as well as line array systems manufactured by Amadeus, including the company’s PMX, UDX and DIVA Series, and includes standard presets that are compatible with all well-known digital crossovers.
