True greatness comes from within.

Just as a singer’s voice has little to do with the size of his body, the physical size of the brand new SON has little to do with its sound. The acoustic furniture, which is only about 90 cm high and equipped with a field coil loudspeaker, is soundwise among the biggest.

As a result of the fine-tuned combination of a unique field coil speaker with an ultra-fast high frequency driver, music played through the SON fills the room with sound, while the technology takes a back seat. The perfect execution of the finest components, accomplished in the Wolf von Langa workplace, will delight; and in conjunction with their award worthy designs, they will fit nicely in any upscale residential ambience. The SON is a perfect speaker for the living room, the music room, the library, or any place in the home where people like to enjoy the sound of their own favorite music. Played loud as quiet, the SON is the right speaker for you.
