The BMS 5530ND and 5531ND compression drivers both use the company’s unique patented design, combining a neodymium magnet assembly, polyester diaphragm, and 44.4 mm copper-clad aluminium sandwich in- and outside voice coil with Kapton former, offering a 113 dB sensitivity (1W/1m) with an extended high frequency response up to 20 kHz in a very small size and low weight, in 8 or 16 Ohm configurations. With the new BMS designs, loudspeaker system designers can create new products with no compromise, while reducing the size, weight and cost of the driver components.

That includes new line arrays and beam steering systems, which will benefit from the reduced 72 mm outside diameter to create very tight, high-output arrays, and deliver maximum output from minimal height. When multiple 5530/5531 drivers are closely mounted, the recommended crossover drops to 850 Hz.

Because of their small size, the BMS 5530ND and 5531ND are the only solution for creating high output beam steering systems with perfect directivity control, low crossover of 850 Hz and 72 mm acoustical distance between sources. In fact the recommended crossover is one octave lower than other drivers in this category, while the maximum output is 4-6 dB higher. This allows the design of high output loudspeaker systems, including high-quality point sources, powerful line arrays and vertical beam-steering columns with high fidelity, high resolution sound and perfect directivity, reducing size, weight and cost.
