distortion. This distortion can and will damage loudspeaker 
components and will not be covered by warranty.

of playing. Additional improvements will be evident after 100 
hours of playing time, at which point the speakers have 
reached their full musical potential. 

Room acoustics and positioning of the speakers within the 
room have an important effect on sound quality. To find the
