In search of the rediscovery of natural sound, Voxativ has gone one step further. With respect to the old Voigt, Jensen and Klangfilm drivers, this type of transducer is now revised using a completely new fieldcoil technology. 

 

The price refers to a matched pair.

Description

The AC-X 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-X 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 designs of the 1920s or Internet based DIY projects, the Voxativ field coil will never reach a temperature limit that can cause voice coil damage. 
 
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.
 
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
