Two new high-frequency drivers and a “bullet” driver are the two latest additions to the growing FaitalPRO line of loudspeaker drivers with ferrite magnet structures. They will on display at the 2012 Prolight+Sound/Musikmesse show later this week in Frankfurt.
The new HF105 compression driver offers a 91 mm total diameter, a 37 mm voice coil, a Ketone Polymer ring diaphragm, and radial phase plug.
Despite the use of a ferrite magnet assembly, the HF105’s weight is just contained at 2.4 pounds (1.1 kg), while it has an elevated efficiency capable of an average 107 dB from 1.4 to 20 KHz. The minimum recommended crossover frequency is at 1.7 KHz, with a nominal power rating of 40 W and a maximum of 80W.
The HF105 is suited for medium and small sized 2-way enclosures and line arrays, coupled with a woofer not over 12 inches. The HF105 is the ferrite version of the HF104 neodymium driver already available, and it brings forth excellent mechanical and acoustic characteristics from the original version—while achieving a slightly different tonality through its optimized ferrite magnet assembly.
The new HF107 compression driver measures 120 mm in diameter and 44 mm voice coil. It is the “big brother” of the HF105, also offering a Ketone Polymer ring diaphragm structure coupled with an innovative single slot annular phase plug,
The average efficiency level of the HF107 is 109 dB from 800 Hz to 20 kHz, the recommended minimum crossover frequency is at 1 kHz, and the nominal power rating is 70 watts and maximum power rating is 140 watts.
The HF107 is recommended in 2-way applications of a certain “importance”, or powerful line arrays with a 12- /15-inch woofer, and weight is 5.3 pounds (2.4 kg). Great care was taken in the study of the single slot annular phase plug in order to help ensure consistency in the response on the whole bandwidth while keeping an excellent extension towards the high frequencies.
The new FD371 bullet driver, complete with aluminum horn with 40-degree conical dispersion, is ready to be used in sound enclosures right out of the box. Incorporating a ferrite magnet assembly, a 37 mm voice coil, and a Ketone Polymer ring diaphragm, it has an average efficiency of 107 dB on a frequency range from 2.5 to 20 kHz, with an impressive minimum crossover frequency at 2.5 kHz.
Nominal power rating is at 35 watts, with a maximum power at 70 watts. It offers a very extended response and controlled directly at the highest frequencies.
The FD371 can be employed in multiple way applications, even with very high crossovers (5, 6, 7 kHz), and it is optimal for medium-sized 2-way systems, given that it may be used down to very low frequencies
Weight is contained, regardless of the use of a ferrite magnet, to 2.6 pounds (1.2 Kg). The size of the frontal squared flange with rounded corners is 102 mm.
The horn and assembly have been purposely studied to perform an acoustic load that extends as much as possible towards the low frequencies, while maintaining good control of directivity towards the higher and uppermost frequencies.
