About The Elementi Audio Onyx Subwoofer

Onyx is a floor mount subwoofer designed to be the primary LFE subwoofer or to balance room modes when used with the larger Obsidian subwoofer. The Onyx can be mounted around the perimeter of the cinema to reinforce and even out the bass response throughout the cinema or placed under the screen. This subwoofer uses a 15” Neodymium ultra-low distortion driver with a 4” voice coil for low power compression and will handle 2,400W of amplifier power. Its energy is focused to produce high SPL and flat frequency response from 30-150Hz and then roll-off down to 20Hz.

All Elementi subwoofer are fully digital and benefit from floating 32 point DSP processing, digital crossovers, FIR filters with correction in the frequency and time domains, look forward speaker protection, high flow PASCAL amplifiers and high quality D/A converters.

Each speaker is custom tested and run in to ensure optimal performance out of the box.
