Our History

BGW Systems, Inc. is a highly successful California corporation engaged in the business of designing, manufacturing, marketing and distributing high quality electronic equipment. BGW has built a strong reputation for building the most rugged, reliable and long lasting products in the industry. BGW's product line includes Audio Power Amplifiers for professional, industrial, commercial, theater and cinema markets, Racks and Rack Mount Accessory Products, Self-powered Subwoofer Systems, Rack Mount Computer Systems, in addition to Custom and OEM products.

During the period from 1968 to mid-1972 the company was engaged in extensive research and development activities. It was during this period that the company developed its first product. At present, the company produces four lines of power amplifiers; the "Professional Series", "Performance Series", "Grand Touring Series", and the BGW "Millennium Series".

In July 1974, BGW Systems was chosen by Universal Studios to supply power amplifiers for use in movie theaters worldwide. These amplifiers were an integral part of Universal's Sensurround sound system featured in "Earthquake", "Midway", and "Rollercoaster". During that period, thousands of BGW Models 750 and 750A's were purchased by Universal. And, most are still being used today in Universal Studios' theme parks.

The company's manufacturing facilities are clean and modern. The Sheet Metal facility is truly State of the Art. The 35 ton computer numerical controlled Turret Punch Press fabricates all panels, chassis and brackets. Bending operations are performed on two Press Brakes--one with numerical control back gauge (one axis); the other has two axes numerical control back gauge. Shearing operations utilize a six foot State of the Art Shear with a computerized gauging system. Graining operations are performed on a special time-saver graining machine. A CNC Machining Center allows fabrication of the balance of metal components and heat sinks. Having this complete facility gives the company the ability to develop new products quickly and to produce high quality packaging for all products.

BGW Systems has earned an enviable reputation for reliability and quality. Testing of the products at various stages of manufacture insures proper operation of each unit. A complete electrical test of each amplifier is performed by a computerized audio test system. The computer prints out the results of each test. Since the first amplifier, each unit has been individually tested. Shaker Table testing is also used on a 100% basis. Each amplifier is operated while strapped to a Shaker Table to determine if any intermittent electrical problems exist. The exclusive modular construction makes BGW amplifiers easy to maintain in the field, if needed. By simply replacing a module, service becomes a quick and easy task.

BGW is also an outstanding OEM supplier to many leading firms including NASA, the U.S. Navy and 3M Corporation, for whom we have designed and manufactured special audio amplifiers and customized computer systems
