The ultimate bookshelf speaker for esoteric audiophiles. The Esoterix Altum is a refined speaker, designed to truly enhance the full two channel listening experience, whether playing old favourites on vinyl, or enjoying the definition and detail of the latest high resolution digital tracks.


In developing this revolutionary speaker, the Krix engineering team paid particular attention to imaging – the meticulously engineered waveguide controls the directivity to present a soundstage much larger than expected. Paired with the renowned Scanspeak Revelator tweeter, the result is an accurate and detailed stereo image, delivering extreme definition with a very smooth response.


The bass and midrange are superbly handled by a 165mm driver incorporating leading edge transducer technology, highlighted by an innovative cast aluminium basket and a large neodymium-iron-boron magnet for increased power handling. Perfectly tuned with the cabinet and sizable double-flared vent, the Esoterix Altum is able to produce bass much larger than its size would suggest.


Detail isn’t only in the sound. The distinctive fully-mitred cabinets provide a seamless look with no visible joins, while the striking prismatic geometry and optional matching stands ensure these bookshelf speakers will look stunning in any environment.


For the ultimate sound experience at home, play it through Krix.

Wow! That was our very first thought when first we heard the Krix Esoterix Altums in our listening room. We’re prepared to bet that that’s what you’ll think too when you hear a pair for the first time.
