Voxativ – AC – X2



The AC-X2 is driven by a large field coil instead of a permanent magnet. With this magnetic force, the driver reaches the physical maximum and an extreme dynamic performance.
The AC-X2 has a Qts between 0.25 and 0.6 depending on the supply voltage which can be set from 6 to 18 volts. It enables the user to adjust the driver to all useful installation conditions and playback requirements. The optimal value in our experience is 12V.
Different to the AC-X unit this driver is equipped with a wooden cone for ultimate bass response. Just imagine how wonderful an open baffle or backloaded horn design will sound using this drive unit. Simply power it up with an 1 watt single ended tube amplifier.
Delivery includes a switching power supply.
Further power supply options are:
• N1 – A transformer power supply 12V fixed
• N3 – An adjustable power supply. Switchable voltage from 12V to 19 V DC in 0.5V steps.
• N2 – A high-end battery power supply 12V fixed, with loading automatics
Enclosure possibilities:
• Fullrange mode in all high-end back-loaded horns (free schedule available)
• Fullrange mode in an open baffle design (free schedule available)
• As a high- and midrange driver combined with a fast dipole woofer
• As a fronthorn driver, fullrange or 2-way
