A loudspeaker mounting technique that aims to eliminate acoustic interference between the sound waves emanating from the front and rear of a driver is commonly employed. This involves effectively isolating the front and rear radiation, preventing them from canceling each other out, particularly at lower frequencies. An example would be mounting a speaker within a very large, sealed enclosure or within a wall, where the wall itself acts as a barrier.
This method is significant because it helps to produce a cleaner, more accurate sound reproduction. By preventing destructive interference, the system allows the full range of frequencies to be heard without unwanted cancellations or reinforcements. Historically, achieving this ideal has been a design goal for audio engineers seeking to improve the perceived audio quality, particularly in home and professional audio applications. Its application contributes significantly to the low-frequency response and clarity.
