    audio impedance
    Pat Brown 07/09/13 10:14 AM,
    The impedance of a loudspeaker characterizes the opposition that it presents to current flowing from the amplifier. The impedance is both complex and frequency-dependent. Complex means that it is not a pure resistance, but a combination of resistance and reactance. As a result, the voltage and current waveforms from the amplifier are not in-phase. Frequency-dependence means that the opposition to current flow varies with the applied frequency – a natural occurrence in a reactive load. The curve in Figure 1… View this story

    FaitalPRO has introduced three new ferrite woofers: the 18-inch 18HW1070, the 12-inch 12FH530, and the 10-inch 10FH530. The new 18HW1070, dubbed the “high-performance subwoofer,” is outfitted with a 4-inch (100 mm) voice coil. It has a rated nominal power handling specification of 1,600 watts AES, with maximum power handling of 3,200 watts. “We wanted to create an 18-inch loudspeaker for subwoofer use that would be similar to our 18XL1600 in terms of acoustic characteristics, power, frequency response, Thiele & Small… View this story

    Bose Professional has expanded its range of RoomMatch array module loudspeakers with the new RMS218 VLF-subwoofer module. The RoomMatch RMS218 subwoofer is designed to integrate with Bose RoomMatch Progressive Directivity Arrays in enhancing program material that extends down to 25 Hz. The RMS218 subwoofer includes dual Bose LF18 18-inch high-excursion, 4.5-inch voice coil, neodymium-magnet transducers. The V-baffle design features a large center port to reduce airflow turbulence and distortion, while minimizing enclosure width to allow integration with all RoomMatch modules.… View this story

    The original Dan Rooney’s Cafe & Bar was established in Pittsburgh in the early 1900’s by the Rooney family—the same family that owns Empire City Casino today. This lively Pittsburgh watering hole has been recreated at Empire City Casino to bring the Rooney family spirit, culture, and story to the people of Westchester and the tri-state area. Recently the nightspot installed a new sound system based upon D.A.S. Audio loudspeaker components to add to the atmosphere of the venue. Pittsburgh,… View this story

    Turbosound Aspect loudspeakers have been deployed at the Café Del Mar in Meydan Beach, Dubai by audio designer Joe Chidiac of Pulse Middle East to help generate a focused, high-energy dance floor sound field. Chidiac was invited to design the venue’s audio, lighting and rigging system based on the solid reputation he has built up in the UAE region, and by the high profile of his audio-visual and lighting design at the Diablo nightclub project in Dubai, which is owned… View this story

    Modifying the directivity characteristics of loudspeaker arrays through electronic delay has become increasingly popular. Whereas 20 years ago the only option was expensive dedicated digital delay units, and a few years later the original BSS Omnidrive was a luxury, the advent of inexpensive digital processing has changed the game. The design of complex arrays using a relatively high number of processing channels, as required to electronically modify the directionality of an array, is now affordable and widely implemented. However, virtual… View this story

    Málaga, one of Europe’s most historic cities, is building a much-needed new metro / subway rail network. And with the expertise of PA / VA integrators LDA AudioTech, Renkus-Heinz Iconyx beam steering loudspeakers will make individual station announcements crystal clear. The main economic and financial center of southern Spain, Málaga thrives on tourism, construction and technology services, while other sectors such as transportation and logistics are beginning to expand, with the growth of the Andalusía Technology Park (PTA) setting a… View this story
