We showed 2 systems in an open plan environment, the aim was to get more people to see the product, rather than trying to get people into a cramped sound room. This worked very well for us. We were showing, in the front, Silver Night PSE & Revolver Cygnis loudspeakers. These speakers were specifically designed to work with our amps. At the rear we were playing a continuous slideshow through our 3 box Elite and Quattro world class pre-amp.
