Voxativ – AC-Pi-Fe



The Voxativ AC-Pi-Fe driver has a magnetic field of 20.000 Gauss.  This makes it become the strongest ferrite-magnet widebander on the market.
This driver is equipped with an underhung coil for full and rich sound. Furthermore, a wooden cone is mounted. With this you can optimize resolution and bass response of your DIY speaker system without compromising an accurate stereo image.
Enclosure possibilities:
• Fullrange mode in all high-end back-loaded horns (free schedule available)
• As a high- and midrange driver combined with a fast dipole woofer
• As a fronthorn driver, fullrange or 2-way
