The 603 S3 is the largest speaker in the 600 Series and is ideal for a large room or home theater. It combines our new Titanium Dome™ tweeter with the accuracy and transparency of our acclaimed Continuum™ Cone FST™ midrange driver.
The two low-end drivers provide enough power to fill the room, while the improved connections and enhanced driver positioning make the 603 S3 our most advanced affordable floorstanding speaker ever.
The new 603 S3 introduces our all-new Titanium Dome tweeter that combines exceptional resolution and insight with smooth, refined high-frequency reproduction. The result? An accurate and immersive experience of your favorite music.
The 603 S3 features our new, acoustically superior tweeter grille mesh originally developed for our acclaimed Signature models. Combined with the new Titanium Dome tweeter, this provides unprecedented resolution and exceptional realism.
With its composite construction, the Continuum Cone avoids the abrupt transition that can degrade the performance of a conventional driver. With the 603 S3, experience a more open and neutral reproduction of voices and instruments, with greater precision and transparency.
The speaker connections of the new 603 S3 are derived from those recently redesigned for our 700 Series. They provide a better layout and a noisier signal path between your amplifier and speakers.
