• The latest generation 4 inch drivers has now been build into the new Qohm sources. The weight is further down to 3.1 Kg.  The specification level is increased also; bringing the sound power level up to 123 dB Lw, and the 50 Hz band level up to 98 dB Lw which is the highest we have seen in the industry.

  • With 3.1 kg, or 9.5 kg for the soft bag with all equipment from amplifier to tripod, it means that building acoustics measurements are now possible for anyone to do, and it no longer requires two persons for a measurement campaign.

  • The McGill university in Montreal Canada has a large set of Qohm sources installed with some dedicated equalization equipment. In the recording research centre at McGill, the very light weight omni-directional sources are used in experiments to influence musicians during their performance recording using replay. And, a set of two of the same Qohm sources are also used when going over the world to investigate the acoustics of large performance sites with exceptional acoustic properties. See the 16 sources suspended over the recording area at McGill in the photo below.
