Onyx Subwoofers

Onyx Subwoofers

Refined Bass
Like the Onyx line of speakers, the Onyx line of Subwoofers from MB Quart are the perfect first step into the High End sound of MB Quart. The Onyx subwoofers feature a thermal formed polypropylene cone and 1.5” aluminum voice coil for strong musical bass. They also feature the same style deep drawn heavy gauge stamped steel basket as Reference along with treated spiders and spring loaded wiring terminals to make installation easy. Match the Onyx subwoofers with Onyx speakers and power them with any of the MB Quart Onyx amplifiers. Onyx subwoofers perform best in vented enclosures.
