Rectangular built-in acoustics

 

— a fairly common form of built-in acoustics. Suitable for any number of speakers and is very popular with multi-way models, although single-way models are also found. One of the main advantages of this shape over the oval one is the presence of a full-fledged cabinet, which to a certain extent smooths out the influence of the wall material on the acoustic properties of the speakers. In addition, marking and preparing a rectangular seat as a whole is noticeably easier than an oval one.
