Hi Scholl.I find most DJ type setups not that good. Some are just about painful. They had a barbaque at work and speakers set up outdoors. You could hear the poor woofers dying. It's not about sound for a lot of these systems. It's just NOISE.
One place where there are some nice sound systems is many movie theatres. I suspect a lot of these are horn loaded. I wonder how many people frequenting this board use horns for home theatre. I use mine for stereo and suspect most people do. My wife listens to surround sound downstairs, I listen to stereo (Pi 7's) upstairs.
Wayne doesn't have a formal "theatre" system suggestion on his list although that's where most people want to be today. It might be worth adding some info on this.
Grant.
