Bookshelf speakers combining performance and value.

Available Finishes:

Soundly based on dynamic balance.

Consisting of one floor-standing and three bookshelf models, the S series offers upcompromised performance with unmatched value. The way tweeters and drivers are matched, the way the crossovers are designed, the way the cabinet mechanics are "voiced" to the components, the way the custom-made screws hold it in place, serve to make the S series a great choice for any indoor home loudspeaker application.

The S8 incorporates the SL5000 Dynamic Balance 1" dome tweeter and the new MW8000 Dynamic Balance 7.5" driver to produce the power and authority of an 8" driver without the typical midrange distortion. A 7.5" bass radiator is incorporated to complete this design. The larger driver, bass radiator, and S Series tweeter produce a level of performance you might expect only from larger floor-standing loudspeakers, yet due to the efficiency of this design it can still be tucked into a bookshelf.
