The FS AC-3B is the logical extension of our successful model AC-2x. Changes were mainly done to the suspension. The big neodymium magnet system got stronger once again.

The suspension material is now a very fine goat leather. This has as a natural substance in comparison to foam or rubber and much better acoustic properties. It reduces the internal friction considerably so that the saved energy is now fully transformed in cone movement and impulse reproduction.

In the listening test you will immediately notice the difference: Much more details. Things are present that were previously swallowed. More purity and again a stronger bass response. The whole music is submitted with an almost royal softness which so far has never been heard - except with our AC-X.

Again a magnetic system is used, were the voice coil is underhung and always working in the homogeneous magnetic field. A new, stronger Neodymium magnet is used whose reserves are never exhausted. The magnetic power is extremely high.

This loudspeaker is simply the best full-range driver for all backloaded horns. No subwoofers needed !
