Lavoce Expands Into the High Frequencies at NAMM 2022

Lavoce Italiana, the professional loudspeaker transducer company used the 2022 NAMM Show to officially launch two Next Generation high frequency drivers with unique features, expanding even more the company's fast growing catalog. The DN14.30TK is Lavoce's new 1.4” exit neodymium compression driver, a refined and more compact driver with a titanium diaphragm. Also new is the BF10.10LA, the company's first entry into the compression tweeter category.

This Test Bench explication focused on the 835PB ferrite 1.4” aluminum diaphragm compression driver, from Radian Audio Engineering. Features for the 835PB 3" diaphragm, 1.4" exit, compression driver includes a 3” polyimide voice coil former with a copper clad aluminum edge wound ribbon wire voice coil, a self-aligning field replaceable diaphragm assembly, and the most important feature, a proprietary processed and hardened aerospace-grade aluminum alloy diaphragm over a three slit phase plug. The 835BP is also available with a beryllium diaphragm. This article was originally published in Voice Coil, February 2020.

This was the first time Test Bench featured a product from the highly respected Radian Audio Engineering. Radian sent the 950PB and the 760NEOPB, two of the company’s flagship compression drivers. The 950PB and the 760NEOPB share several features. They are both 2” exit compression drivers, with a useful response above 10 kHz. The 950PB and the 760NEOPB use neodymium motor structures and pure aluminum diaphragms with a proprietary mylar suspension that greatly reduces second- and third-order harmonic distortion. The two transducers mainly differ with regard to their voice coil diameters. This article was originally published in Voice Coil, November 2014.

This Test Bench focused on a ribbon driver from Bozhen New Audio Lab. The CQ76 is a ribbon loudspeaker designed for household hi-fidelity systems as a mid-high unit, featuring a crossover frequency at 1500Hz and very low distortion under high power output.
