The name Concentro signifies the extraordinary in every respect. The compact Concentro S 503 masterfully delivers the ‘wow factor’ from a surprisingly small package.
AS-XR technology Unique, eye-catching, and acoustically ideal: the crystalline shape of the membrane provides the perfect balance of stiffness and damping.
Modern Hybrid Design The progressive design elements from the Concentro Series combine with the clean lines of the Vela Series to create a strong visual presence.
StepX-JET Since no two rooms are the same, midrange directivity can be adjusted using the exchangeable DCRs supplied.
Be in no doubt, the S 503 is a true Concentro in every respect. Design features and technical details that drove the success of the S 507 and S 509 are now combined in compact dimensions. The trapezoid basic shape, convex shaped baffle, and gently angled cabinet combine in a strikingly organic way to create a strong visual statement.
The extensive list of patented features and the revised woofer magnet system guarantee superlative sound. The effortless performance can be adjusted to suit the room acoustics. Close your eyes and you’ll instantly forget you’re listening to a compact speaker … all you hear is music.
The Concentro S 503 is available in black and white highgloss finishes and in high-gloss walnut veneer. The LS 100 stand specially developed for the Concentro S 503 is an available option.
