At the Rocky Mountain Video Fest, Emerald Physics displayed its new sets of emerald physics 2.7 loudspeakers. They feature bi amplification and are dsp controlled. These are driven by the Phoebe II Amplifiers. This system provides huge spread spectral technology providing all enveloping sound by Wyred 4 Sound. The voice and instrumentation is simply amazing (according to this video review anyway): the singers voice appear to be hanging in space with the base thundering about with the instruments clear and crisp. The sound system really appears to be next generation as the music to the listener appears to be circling around the room. The narrator is amazed and compliments the audio team.
