Part of the Krix Architectural Series (AS), the Hemispherix A20 can be used for home theatre, stereo listening, or high-quality background music. It features a 20 degree angled baffle to project the sound to your primary listening area, meaning less sound is reflected off walls and other surfaces. Your experience is clearer, there is a more three-dimensional soundstage, better definition for music listening, more articulate dialogue, and more realistic and involving sound effects in movies.

The fully-enclosed back box maximises and controls bass, protects from ceiling debris and drastically reduces sound leakage into adjoining rooms. With speaker components mounted directly to the front baffle of the speaker, the Hemispherix A20 delivers a true high fidelity sound in a neat package.

Tonally balanced to the Krix floorstanding and bookshelf range, the Hemispherix A20 allows you to enjoy accurate and controlled bass, as well as midrange clarity delivered by a 100mm driver with a large magnet and aluminium shorting ring. Extended high frequency performance is provided by the 26mm ring radiator tweeter.

The paintable bezel grille, which is slim and attractively-styled in rust-resistant stainless steel, locks onto magnets at the front of the speaker for easy installation, producing the ultimate sound with magical simplicity.
