603 S3

The 603 S3 is the largest loudspeaker in the 600 Series and is ideal for larger rooms and home theaters. It combines our new Titanium Dome™ tweeter with the accuracy and transparency of our acclaimed Continuum™ cone FST™ midrange driver.

A celebration of sound

Room-filling scale and authority come courtesy of two bass drivers, while improved terminals and enhanced drive unit positioning make 603 S3 the most sophisticated affordable tower speaker we've ever made.

607 S3

Offering power and scale that belies its compact form, the 607 S3 bookshelf speaker combines our new Titanium Dome™ tweeter with the accuracy and transparency of our acclaimed Continuum™ bass/midrange cone.
