The Volcanix is designed to fit behind acoustically transparent screens and other shallow locations, this is one versatile subwoofer. Don’t let the ‘slim’ name fool you, this subwoofer combines enormous punch with deep extension to fill you room with bass.

  • Down firing dual ports
  • Includes Grille
  • Heavily braced enclosure

Welcome to the profound experience of true low-frequency effects with the Volcanix Slim, a dedicated home cinema in-room subwoofer. Experience stunning depth and realism in cars chases, building explosions and rumbling earthquakes, while also benefiting from tonal accuracy and the enhanced bass performance you need to truly feel a rock concert or the strings of a symphony orchestra.

The built-in ICEpower® class D amplifier delivers 450 watts RMS, while the large 305mm bass driver, with huge 50mm long throw voice coil, is specifically developed for low frequency reinforcement. With two large down-firing ports to give a 40% larger vent area than the Volcanix, the Volcanix Slim provides improved bass performance at higher volumes.

Its front mounted control panel with LED display allows easy adjustments, while proprietary Krix rubber feet improve acoustic isolation on hard and soft floor surfaces. Available without a front grille, for use behind an acoustically transparent screen, or with a front grille for those displayed in full view.

Ask today why 60% of Australian cinema's use Krix cinema speakers. Sydney Hi Fi Mona Vale offers a full custom design and installation service that will give you the absolute best sound coupled with peerless industry service.
