I saw contraperture acoustics on the Internet once. (contraperture acoustics -http://www.pana.com.ru/eng/objects/things/112 ), in which the speakers are positioned facing each other. It's an interesting idea, but I didn't like the design. I wanted this model to look more modern. Link to the model: https://3ddd.ru/3dmodels/show/akusticheskaia_sistema_model_moego_dizaina
