I have a complicated install for a unusual bar/restaurant that I could really use some insight into. The location has a series of 4 interconnected rooms and a outdoor patio/courtyard. None of the rooms are larger than 350 sq.ft. The site is a restaurant with a very popular bar/lounge scene which starts to ramp up after dinner service is over. They have D.J. in two to three nights a week and a capacity of 175 people. Each zone needs to be able to have the volume controlled individually and all zones always play the same source. My question is, since this is a venue where high quality audio is a priority and volume levels can get elevated ( but not to the level of a dance club or live music venue) is a 70v system capable of high quality sound or should I stick with a stereo amp speaker set up? Thanks, Jim
