If you are in a desert and having a band performing in front of a wall is better than having a band performing in a desert. Space without boundaries is evil. You have no reflected sound waves and everything is dissipated in a space, an open space. Reflections are important, especially the first reflections.
Sometimes bothers me the question what is the meaning of all this endless chasing of the perfect sound? Looking on it objectively it is a pain. First of all one puts a lot of effort gathering the knowledge, because it is something that requires hundreds of hours of reading and digging into that matter. Then hours of voluntary work have been put into modifying or creating components. I’ve spend weekends braiding cables, creating custom wooden compartments for filters, adjusting damping material of the speakers, soldering cables, glueing and grinding wood and so on. Sometimes I am asking myself why didn’t I spent this time doing something sensible?
Speakers are the most important component in an audio chain. I can’t remember any other component that has influenced my home audio system as much as speakers did. Speakers disperse the sound waves inside the room interacting with its boundaries and one shouldn’t think about them separately but in conjunction with the particular room.
