What makes a 'loudspeaker' any different to a studio monitor, or bookshelf etc, they look basically the same?
In the old days, monitors were for analysis, loudspeakers for listening.
In the 80's Yamaha NS-10 loudspeakers became ubiquitous pop music small monitors in studios. IMO, sonics suffered from using them. Later Genelec self powered. I never cared for either, monitoring or listening.
