HiWave BMR12 Compact 2" Full-Range Square Speaker 12W 8 Ohm NXT New Transducers Limited
Balanced Mode Radiator
HiWave BMR Series are the first full-range, off-the-shelf drive units using HiWave's patented BMR technology. Square BMR12 2" drivers combine the qualities of HiWave's flat panel speakers and the pistonic movement of conventional speakers. The technology's wide directivity enables flexible placement options, while the wide frequency response means BMR drivers can also deliver cost savings to engineers, since no crossover components or frequency-specific drivers are required. Excellent for line arrays or most any other type of sound project where space is limited and sound performance can't be sacrificed!
The BMR12 2" drive unit has an excellent and extended frequency response with wide directivity and is ideally suited to compact full-range applications that require a high performance acoustic solution.
