FaitalPro is targeting manufacturers of portable speakers with the pair of new compression drivers added to its HF range. The ferrite magnet HF111 and neodymium HF142 have been designed with reduced dimensions and at a lower weight than their predecessors.

The HF111 is a medium-sized compression driver featuring a 37mm voice coil and 1-inch mouth. It has a domed diaphragm constructed from ketone polymer and offers deliberately balanced, controlled parameters so as to make the unit compatible with a wide range of applications. The manufacturer also claims an efficiency of 107dB with a frequency response of between 2kHz and 20kHz and 40W of applicable power, in addition to a maximum of 80W AES. HF111 is designed specifically for use in two-way systems with a horn compatible with its 1-inch throat, as well as in multi purpose systems with a 10-inch companion woofer. Its linear response and frequency extension also make it suitable for use in smaller line array systems.

Suggested applications for the HF142 include use in large monitors, two-way systems, alongside a 1.4-inch horn or large woofer, in a line array with a waveguide or flanked by a woofer or a midrange system of large dimensions. A large drive with a 65mm coil, ¼-inch throat and a magnetic circuit with a neodymium ring, it also has a ketone polymer membrane and possesses a 4-slot phase plug. It’s capable of handling continuous power of 80W and a maximum of 160W. It has a 110dB efficiency and range from 900Hz to 18kHz.

On the lower end of the frequency range, the 12RS550 is a 12-inch woofer with ferrite magnet. It is aimed at those producing two- or three-way speakers for use in a variety applications, such as in clubs or as studio monitors. Its EBP is 108Hz and it has an efficiency of 93dB with typical bass use from 45Hz to 2,500Hz. It houses a 77mm voice coil and boasts a maximum power of 1,000W with 500W nominal.

Then there’s the 10PR320 and 12PR320, 10- and 12-inch woofers that mark an evolution of FaitalPro’s previous PR300 models. Based on a more flexible magnetic circuit, these are described as ideal for where ‘woofers are needed to extend the low frequency response beyond the standard products available’. Each includes a 65mm, 2.5-inch coil with a 600W maximum power by AES standards.

In other news, improvements have to been made to ‘stabilise’ the dome titanium for the manufacturer’s HF drivers with 74mm voice coils. This is achieved by added a specific treatment on the outer diameter of the diaphragm suspension clamping. The result is said to be more stability and linearity in the response.
