UK - NXT plc, best known for its flat panel loudspeaker technology, recently announced the launch of its Balanced Mode Radiator (BMR) technology. BMR, the company says, builds on NXT's expertise in bending wave physics by using a unique balancing technique, which allows flat panels to be used in wide bandwidth drive units. The panels, which can be either circular or rectangular, are mounted in a chassis much like a conventional drive unit. This similarity aids the manufacturing process, allowing BMR drive units to be built using conventional loudspeaker techniques.

While BMR's low frequency performance is equivalent to conventional drive units of the same size, the high frequency range is extended with the wide directivity characteristic of all NXT technologies. Increasing the bandwidth in this way means that the number of drivers required to cover a given frequency range can be reduced. As the technology is scalable, full-range drivers are feasible, potentially eliminating any requirement for low frequency-specific loudspeakers.

BMR is suited to a broad range of applications, with the rectangular devices particularly suitable for slimline aesthetic designs. NXT chief technology officer, Henry Azima, commented: "10 years after the filing of the original Distributed Mode Loudspeaker (DML) patents, our development teams continue to invent and evolve our existing technologies. The latest NXT technology is a result of our commitment to inventiveness and underlines our expertise in the field of bending wave physics."
