The new ultra-flat UA-131-UF speaker is here! With only 5 cm depth it is a true problem solver. The speaker fits behind a flat fabric tension frame and can be perfectly integrated into any interior. Another use case is as an L-C-R system behind a screen, making an ultra-flat home theater solution possible. There are numerous possibilities and problems that the new UA-131-UF can address and solve. The overall performance is comparable to that of a very good bookshelf speaker, thanks to an elaborate bass reflex design in the enclosure. Soon, this model range will be complemented by subwoofer models that are also only 5 cm deep.
