The Italian R&D team at Lavoce created the new DN10.143 and DF10.143 by optimizing the complex methodology of annular diaphragm design and adopting their successful Next Generation development approach for compression drivers. From the original design concept this optimizes every aspect of performance target and production process to ensure the perfect balance of a high-quality acoustic performance with consistency, reliability, and cost.
The optimized annular diaphragm design used in the DN10.143 and DF10.143 compression drivers has the advantage of delivering higher sensitivity and extended low frequency performance than typical dome diaphragm designs. This also presents a lower distortion characteristic across the whole operating frequency range, which is further enhanced by the first break-up modes of the annular diaphragm exhibiting at a higher frequency. Both models specify a conservative 1800Hz recommended crossover point, so together with their high sensitivity, wide usable frequency range and low distortion characteristic, they add another interesting flavor to Lavoce's established range of 1" exit compression drivers.
The DF10.143 has a ferrite magnet motor structure and offers 35W AES power rating with 107.5dB sensitivity, and a frequency range of 1200Hz to 20000Hz. Using the same 1.4" edgewound copper-clad aluminum voice coil and one-piece high temperature polymer annular diaphragm and surround, it offers similar benefits as the DN10.143 but with an obvious price advantage. This makes the DF10.143 the perfect solution for pushing the operating HF bandwidth limits for more cost-conscious line array projects or high-output 2-way or 3-way cabinet designs.
"Since launching the first model of our Next-Generation range of compression drivers in 2019, we are very happy to have gained the attention of many of the worlds’ most renowned pro audio brands, so enhancing our range with Annular diaphragm models is a logical next step. We are also proud of the perfect synergy our state-of-the-art Italian R&D center and wholly owned manufacturing plant in China offers our customers, and for sure DN10.143 and DF10.143 further exemplifies this unique proposition," says Pierpaolo DeMinicis, Pro Audio Division Manager.
New 6.5" Common HF/LF Magnet Coaxial
The new Lavoce CSF061.71K is a professional ferrite magnet 6.5" coaxial with a precision crafted common HF/LF motor which has been carefully optimized by their Italian R&D team and compliments the 8" version, CSF082.00K, launched in 2021. Both models form the beginning of a wider range of steel basket common motor coaxials with 10", 12" and 15" sizes coming later in 2023. All the models are designed to offer premium point-source solutions with a price-competitive edge.
Every Lavoce common HF/LF magnet model offers an instant point-source solution and feature common magnet ‘optimized flux’ motors which bring the LF and HF voice coils in closer unification than traditional coaxial designs. This better combines their acoustic centers for improved coherency, dispersion and alignment optimization in a lighter weight and compact package.
"Our R&D team based in Potenza Picena have really harnessed the complex nature of common HF/LF magnet coaxial design to produce an attractive premium performance coaxial proposition. We are experiencing a high level of interest in this category for portable and install applications, so CSF061.71K is a welcome addition which will offer system designers a higher power 6.5” coaxial solution for single point-source projects or as the mid-high in a three-way system," explains Kevin Shove, Lavoce's International Sales Director.
