The HF105 Compression Driver is a driver for high frequencies, with a 91mm total diameter, a 37mmvoice coil, a Ketone Polymer ring diaphragm and radial phase plug.
The HF107 Compression Driver, the second new model in the high frequency range measures 120mm in diameter.
The FD371 model is a Bullet Driver and comes with a frontal aluminium horn, so this driver is ready to be used in sound enclosures right out of the box. Incorporating a ferrite magnet assembly, a 37mm voice coil, Ketone Polymer ring diaphragm, horn loaded with central ogive; 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.
It can be employed in multiple way applications, even with very high crossovers (5, 6, 7 KHz) and it is optimal for medium sized two-way systems as well, given that it may be used down to very low frequencies for the type of product.
