603 S3 Tower Speaker

The 603 S3 stands as the largest offering within the 600 Series, catering perfectly to expansive rooms and home theater setups. It seamlessly melds our revolutionary Titanium Dome™ tweeter with the precision and clarity embodied by the renowned Continuum™ cone FST™ midrange driver.

A Symphony of Sound

Harnessing commanding scale and authority, the 603 S3 employs dual bass drivers to fill the room, while refined terminals and advanced drive unit positioning establish it as the pinnacle of budget-friendly tower speakers in terms of sophistication.

Elegant Layers of Detail

The all-new 603 S3 ushers in the introduction of our exceptional Titanium Dome tweeter, uniting unparalleled resolution and insight with a polished, fluid high-frequency reproduction. The outcome? A true-to-life and immersive window into your favored music.

Remarkable Audio Realism

Incorporating a grille mesh for the tweeter that's even more acoustically transparent, a concept derived from our revered Signature models, the 603 S3 achieves extraordinary resolution and realism alongside the novel Titanium Dome tweeter.

Precision and Transparency in Sound

Thanks to its composite construction, the Continuum cone circumvents the abrupt shifts in behavior that often hinder the performance of conventional drive units. With the 603 S3, experience a performance that's more open, neutral, and characterized by the utmost precision and transparency in delivering vocals and instruments.

Upgraded Connectivity

Pioneered from the speaker terminals introduced in our acclaimed 700 Series range, the speaker terminals featured on the new 603 S3 boast a refined layout and an unobstructed signal path, ensuring optimal connection between your amplifier and loudspeakers.
