Part of the Krix Architectural Series (AS), the Hemispherix SPS is a single point stereo speaker with dual tweeters and a dual voice coil woofer, providing unsurpassed performance in a very compact package. Two inputs allow both left and right channels to be connected for stereo sound from a single speaker, making it ideal for use in applications where installing two speakers is not desired or practical. The product is therefore perfect for use in hallways, bathrooms, eaves, under balconies and other tight spaces.


The Hemispherix SPS features a 125mm (5”) mid-bass driver with a durable polypropylene cone and an oversized, low distortion magnet system. Two high-grade 20mm (½”) ring radiator tweeters are mounted at opposing 20° angles, providing room-filling stereo sound.


Manufactured from weather resistant materials and featuring a rust resistant stainless steel grille, the Hemispherix SPS is suitable for installation outside under alfresco areas and in eaves, or inside the house in bathrooms, ensuites, or any other room. The semi-enclosed design means that the moving parts of the speaker are protected from dust and other ceiling contaminants while providing excellent bass performance for such a low profile speaker.


The  paintable  bezel  grille,  which  is  slim  and  attractively-styled,  locks  onto  magnets  at  the  front  of  the  speaker  for  easy  installation,  delivering  high fidelity  sound  with  magical simplicity.

“Can in-ceiling speakers deliver a truly musical sound, rather than mere background music? When it’s a stereo indoor-outdoor model from South Australia’s loudspeaker maker Krix, the answer is a remarkable ‘yes’.”
