S3X-H - Yes, even better The S3A is one of ADAM’s most famous models and is found in many of the most prestigious recording studios all over the world. The successor of this world famous model is the S3X-H, a monitor second to none within its size and price point. Unlike the S3A, the new X-model incorporates a 4” HexaCone-midrange as part of the redesigned construction to further improve the musically most important midrange. This new design provides more detail with improved radiation characteristics while presenting a musically coherent sound. To produce deep, tight bass both woofers now work within the same frequency range and radiate symmetrically. This allows for a problem free installation in any multi-channel application.
