15" ultra low distortion woofer, extended frequency response down to 35 Hz (-6 dB)

  • The U15 is a 15” compact subwoofer that provides powerful low frequency response. Low port compression and optimised enclosure design give a tight, accurate bass response that is ideally suited for mobile and installation applications.

Main Features

  • 15″ ultra low distortion woofer
  • Extended frequency range: 35 Hz – 150 Hz (-6 dB)
  • Power handling: 1000 W (AES)
  • Maximum SPL: 133 dB (peak)
  • System impedance optimised for smaller LINUS Loudspeaker Management Amplifiers

State-of-the-art drivers

The U15-Sub is equipped with an extremely long excursion 15” ultra low distortion woofer. The motor delivers extreme high magnetic flux for increased efficiency. The 3” voice coil is 32 mm high, ensuring ultra linear excursion of 22 mm/pp at consistent magnetic force.

State-of-the-art carbon-fiber cone ensures maximum stiffness and low moving mass.

The aluminum shorting rings reduce intermodulation distortion, minimise induction variation while 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.

System solution

The U15-Sub is designed to work exclusively with CODA Audio LINUS amplifiers as an integrated solution for DSP control, amplification, network remote control and diagnostic.  The integrated solution ensures optimal performance and protection. 

Matching the Impedance of Speakers and Amplifiers

Although U15-Sub can work with all LINUS amplifiers the 4 Ohm speaker impedance is optimised to draw more current from a smaller amplifier like LINUS5-C delivering uncompromised high output at reduced system cost.


The U15-Sub is perfectly suited as a sub-extension for the HOPS, TiRAY, CoRAY, D-Series and G-Series systems and can be used in variety of installation and mobile applications.

Typical applications are Houses of Worship, Theatres, Clubs and live sound events.
