Electric horn shell is what to do

Most loudspeaker systems consist of drivers mounted in an enclosure,STR-Z4302

 or cabinet. The role of the enclosure is to provide a place to physically mount the drivers, and to preventM48T02-200PC1

 sound waves emanating from the back of a driver from interfering destructively with those from the front; these typically cause cancellationsSTTA1206DI

 (e.g., comb filtering) and significantly alter the level and quality of sound at low frequencies.The simplest driver mount is a flat panel (i.e., baffle) with the driversstr6454

 mounted in holes in it. However, in this approach, sound frequencies with a wavelength longer than the baffle dimensions are canceled out, because the antiphase radiation from the rear of the cone interferesm56730

 with the radiation from the front. With an infinitely large panel, this interference could be entirely prevented. A sufficiently large sealed box can approach this behavior
