STEG SG650C Component set

In terms of design and technology, the STEG philosophy is continued without exception:
The gentle, precious appearance reveals a number of smart details like the new, hemispherical shaped dust cap for an optimized frequency response in the upper midrange area, the perfectly linear magnet structure for lowest possible distortion, the multiple ventilated voice-coil for high power handling as well as the rigid and aerodynamically efficient die cast basket. Used as a provider of low-frequencies the Q65C finalizes audiophile sound concepts that are designed entirely for authentic musical reproduction and enjoyment.
