  • Trimless magnetic grille
  • Fits inside 70mm wall cavity
  • Fully enclosed backbox

Designed for use as both fronts and surrounds, the IW-30 will disappear into the room, leaving you to enjoy the soundtrack.


The IW-30 is a compact in-wall speaker, ideal for creating a two channel music or multichannel home theatre experience. With performance surpassing its size, the IW-30 is well suited to small to medium home theatre rooms as main or surround speakers, or as a left and right pair for stereo music.

As a rectangular in wall version of the in ceiling IC-30 (Hemispherix AS) and IC-32 (Hemispherix A20) speakers, the IW-30 offers precise tonal matching, but will also provide excellent synergy with any of the Krix speaker range. Designed to fit within a 70mm wall cavity, its fully enclosed back box ensures acoustic integrity and prevents rear sound radiation from being transferred to adjoining rooms.

Bass and midrange clarity are delivered through the 100mm bass driver, while the 20mm ring radiator tweeter sits within an integrated waveguide for improved dispersion. The single piece trimless grille is held in place by magnets at the front of the speaker, and can be painted to match the decor of any room.

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