As a leading manufacturer of loudspeakers, Energy Speaker Systems takes great pride in the construction of speakers. While the manufacturing process of many of our speakers in extremely complex and proprietary, we've presented some images here from our factory, from our woodshop, driver assembly, to final production. Energy employees work diligently, with the latest materials, technology and equipment, to make the most consistent, highest quality products on the market today.
Using MDF (medium density fiberboard) as a starting point, the life of a speaker starts to take shape. MDF is used because it is extremely rigid and inherently resonance free, making for an inert cabinet, which does not color sound. Large sheets of MDF are taken to one of several large CNC (computer numeric control) machines, which are connected to sophisticated computers. Programs are designed for every speaker made, and each piece of MDF is sent through a CNC routing machine, where it is shaped and all holes are cut. Special grooves are cut into the wood, to allow for extremely strong joints when the cabinet is completed. The use of these extremely complex and expensive machines is extremely accurate and consistent cuts, ensuring every speaker built is identical.
At the other end of the building speakers are being built. As an extremely complicated process, that is very time consuming, driver assembly allows Energy to control every aspect of construction, ensuring our extremely high standards are met. The process begins by assembling a basket with a magnet (or two) and attaching the cone, voice coil, spider and dust cap. This process takes place in a matter of minutes, and using special adhesives, strength and durability are ensured. At the end of the each driver line each speaker goes through rigorous testing, to ensure it meets our standards for quality, in terms of sound quality and looks. Right next to the driver assembly line is our amplifier assembly line. As a leader in subwoofer design and construction, Energy designs and builds its own amplifiers, ensuring the quality customers demand. This assembly process mates heat sinks with circuit boards, power supplies and the controls that make an amplifier work. Highly trained workers ensure that our quality standards are met, and each amplifier that is built is tested using the latest in computer technology.
The last stage of making a speaker involves final assembly. This is the point where the cabinet is assembled and glued together, drivers and crossover are installed into the cabinet and all insulation and bracing is installed. Highly skilled workers who are extensively trained complete these tasks, with incredible precision. After assembly, every speaker is tested in an anechoic chamber, in conjunction with exclusive software, is measured next to our reference cabinet. Using the tightest tolerances in the industry, we ensure that the 1st and 1000th speaker off our assembly line sound exactly the same.
