Why should one bother trying to understand basic acoustics? The most simple (and correct) answer is that study of basic concepts enables one to sort through the truth, semi-truth, myths and flat-out errors that pervade the pro audio industry. The fundamentals of acoustics (and physics) do not change, although some “experts” try to prove otherwise. New equipment, toys and theories come and go, but the basic building blocks of sound and its related concepts do not. If university level training…

Sound Waves Sound moves through the air like waves in water. Sound waves consist of pressure variations traveling through the air. When the sound wave travels, it compresses air molecules together at one point. This is called the high pressure zone or positive component(+). After the compression, an expansion of molecules occurs. This is the low pressure zone or negative component(-). This process continues along the path of the sound wave until its energy becomes too weak to hear. The…

This time in Real World Gear we look at the big guns - large format line arrays, those with 12-inch and larger woofers. Line arrays are modular, multi-way enclosures arrayed in vertical columns, with their cabinet’s geometry optimized to provide full-frequency transducer coupling from one enclosure to the next along the height of the array. This is achieved at lower frequencies with cone transducers forming a column from one cabinet to the next, at frequencies where the distance between their…

The TM Array is actually nothing but a line array in the vertical, and a point source in the horizontal. Line arrays in theory are based on omni-directional sources, placed relatively close together, so subwoofers are the perfect choice for building a line array just by their nature. The vertical coverage is controlled by the (vertical) length of the array. Ten boxes, which is a length of about six meters, provide a good directivity down to frequencies of about 45…
