Now you can feel music & movies.
The booming bass of the music, a goosebump-inducing explosion in the movie or a captivating scene in your favourite game - nothing makes you feel audio entertainment as intensely as a subwoofer. The 10-, 12- and 15-inch woofers of the Monolith™ series let you experience auditory entertainment completely anew. The 500-1000 watt RMS amplifiers give the subwoofer the necessary power to display the lows as accurately and powerfully as if you were right in the middle of the action.
Powerful punch, spacious sizes.
The drivers of the Monolith™ subwoofers have been completely revised and now make an even bigger statement in terms of performance, clarity and linearity. Inaddition to the technology, the exterior has also been revised and is now evenslimmer and of higher quality. All the individual needs are taken care of.Should it be a slightly more compact 10-inch Woofer, or the enormously powerful15-inch flagship? You decide!


If THX® is onit, you're guaranteed high quality.
The accurate basses, which sound in a frequency range well below 20 Hz, are produced by THX®-certified technology. This is important to us, as THX® has stood for constant top-level quality in the field of audio engineering for over 40 years. In the certification process, values like output level, distortion and the signal-to-noise ratio are tested.
