ULTRA speakers are designed for the most demanding music lover.

Carefully built by hand with the best materials and selected in pairs, they are delivered in fine wooden boxes.

The mid-bass driver ULTRA K-165 uses a high-tech fabric cone “Made in Germany” in conjunction with linear suspension and a narrow-tolerance copper voice coil with a linearized NEO motor.
Built in a filigree aluminum basket for optimal air flow, these are the ingredients for outstanding neutrality and sound quality.

The tweeter ULTRA T-30 with its 30mm coated silk dome is characterized by a particularly low resonance frequency and extreme neutrality. The linearized NEO magnet system with the complex rear ventilation of the cone in the solid aluminum housing enables the wonderfully spatial and precise audio reproduction with an extremely wide frequency range.
