Why buy direct
Layered, beautiful details
The new 603 S3 introduces our all-new Titanium Dome tweeter, which combines exceptional resolution and insight with smooth, refined high-frequency reproduction. The result? An accurate and immersive insight into your favorite music.
Truly amazing sound
603 S3 introduces our new and even more acoustically transparent tweeter grille mesh, first developed for our revered Signature models. Alongside the new Titanium Dome tweeter, the resolution and realism is exceptional.
Precision and transparency
Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. With 603 S3, experience a more open, neutral performance that delivers voices and instruments with precision and transparency.
Upgraded speaker terminals
Derived from the speaker terminals recently introduced in our 700 Series range, the speaker terminals on the new 603 S3 feature an improved layout and a cleaner signal path between your amplifier and your loudspeakers.
Add a subwoofer for deeper bass
Whether you have a traditional hi-fi system or home theatre set up, a subwoofer allows you to experience fuller sound, richer detail, and a more immersive listening experience.
Power your listening experience
AV Receivers provide the brains and brawn of a home theatre system while amplifiers are the heart of a hi-fi system. Take care to choose one that's perfectly suited for your requirements, including the features you need and having enough power to drive your loudspeakers.
