Helix S 6X coaxial speakers (165 mm).

Helix S 6X - 2-Way Coaxial Speakers 6.5" (165 mm).
 

Sound quality meets elegance – The S speaker series turns every ride into a special sound experience. 
In addition to the novel, timelessly elegant design, the 2-way coaxial system offers an exceptional sound quality. 
Uniquely sensitive and crystal clear, the silk dome of the tweeter conjures the music into the room. 
Due to its central position inside the mid-woofer, the music is perceived as a point sound source and thus optimizes the tonal balance. 
The result: an incredibly homogeneous and natural sound.
