|Alcons Audio's pro-ribbon technology takes a giant leap forward with the development of the RBN1801 pro-ribbon driver. The RBN1801 is a mid/high frequency transducer designed for high output and high fidelity professional sound reproduction applications. Based on the principles of Isophasic planar driver technology, the RBN1801 provides an effective radiation length of 18" (46cm), offers an extreme power handling of 3kW for 200ms, and a high efficiency of 108dB with 1Watt @ 1m. With a 90° wave-guide, the efficiency reaches 110dB. Featuring a frequency range of 1 kHz to 20 kHz. (±3dB) the RBN1801 sports a maximum SPL of 145dB.
"We wanted to explore the possibilities of increasing the performance of the RBN601, our initial pro-ribbon driver and evolution platform for the RBN-series of ribbon transducers," says Philip de Haan, head of Alcons Audio R&D. "We already downscaled the patented 601 into the 401, which is used in our LR14 ultra-compact line-array and VR8 compact monitor. With our research going further into array-technology, the need existed for a larger, single-diaphragm driver. As a driver with these required specifications simply didn't exist, the necessity arose to develop this driver ourselves."
De Haan continues: "Because of enlarging the engine of the driver, we encountered a totally different set of physical challenges that we had to cope with; not only in the development stage but also in the production process where each driver should be manufactured within 1dB deviation."
Tom Back, Alcons Audio's managing director adds: "The RBN1801 will become the platform for a range of new, evolutionary solutions for installed sound, live sound, cinema audio, and the recording studio market, starting with the upcoming Q-series."
