The U4-Sub is equipped with twin extremely long excursion 18″ ultra low distortion woofers. The strong motor delivers extreme high magnetic flux for increased efficiency. The 4″ voice coil is 32 mm high, ensuring ultra linear excursion of 20 mm / pp at consistent magnetic force.
The state-of-the-art carbon-fiber cone ensures maximum stiffness and low moving mass. Three aluminum shorting rings reduce intermodulation distortion, minimising induction variation whilst reducing thermal compression. This design dramatically reduces the distortion of a typical subwoofer at longer excursion levels, and improves the overall sound quality and performance characteristics of the cabinet.
The U4-Sub has been designed to work exclusively with CODA Audio LINUS Loudspeaker Management Amplifiers as an integrated solution for DSP, amplification, network remote control, optimal performance, protection, as well as extensive possibilities for system tuning and monitoring.
The U4-Sub is perfectly suited as a sub-extension for G-Series, CUE-Series and TiRAY, extending the system performance down to 30 Hz. Typical applications are dance clubs, theatres, houses of worship and live sound venues.
