12" neodymium ultra low distortion woofer, extended frequency response down to 38 Hz (-6 dB)

  • The U12 is a 12” ultra 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

  • CODA Audio 12″ neodymium ultra low distortion woofer
  • Extended frequency response down to 38 Hz (-6 dB)
  • System impedance optimised for smaller LINUS amplifiers
  • Maximum SPL 130 dB (peak)

State-of-the-art drivers

The U12 is equipped with an extremely long excursion 12” neodymium ultra low distortion woofer. The neodymium motor delivers extreme high magnetic flux for increased efficiency. The 3” voice coil is 26 mm high, ensuring ultra linear excursion of 16 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 U12 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 U12 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 U12 is perfectly suited as a sub-extension for the HOPS, CoRAY and D-Series systems and can be used in variety of installation and mobile applications.

Typical applications are Houses of Worship, Theatres, Small clubs, Mobile DJs and live sound events.
