AC - X2

 

The rediscovery of natural sound: 
Voxativ fieldcoil technology combined with a cone made from real wood. 

 

The price refers to a matched pair.

Description

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
