Bag End loudspeakers began in 1976 in a small shop by people dedicated to the pursuit of making high quality loudspeaker systems. Over the decades Bag End has employed the very best construction techniques and innovative acoustical designs into their products. The ground breaking introductions of Time-Align and ELF Technologies into sound reinforcement and studio monitor loudspeakers in the 1980’s was followed by Minima One self-powered systems, the highly unique E-Trap electronic bass trap and the Neptune series of ultra performance high power systems. Over the decades Bag End has been a leader in providing uniquely good sounding products and extraordinary service to our customers world wide.

    The beginning

    Bag End officially began in 1976 but the roots go back to 1968 when Jim and Henry first met in their high school theater department. In the early 70’s interest in live theater, music and rock bands intensified, of special interest was sound equipment. Throughout the early 70’s they constantly built and rebuilt speaker systems for their band. By the mid seventies other bands were asking them to build sound systems and, mostly by accident, a company was formed to build sound systems.

    Bag End was formed

    Bag End officially formed in 1976 in the basement of 134 West Slade in Palatine Illinois. This was Bill Schwingel’s house, a third partner at the time. The house is now preserved as a historical building (although not because Bag End was founded there). Over the next few years the company built a national reputation for high quality speaker systems. The company expanded to include a second basement and garage. In 1979 Bag End moved into an industrial building in Barrington, Illinois. The company headquarters remained in Barrington for the next 35 years. In 2014 the company moved into a larger facility in Algonquin, Illinois

    Throughout the next 30 years musicians, recording engineers, churches, theaters, nightclubs, museums and more found Bag End loudspeakers to be the most excellent available.  Our photo gallery highlights some of the products, users and applications over time.

    A decade later Bag End introduced the first widely available Extended Low Frequency (ELF) system based upon the Long/Wickersham ELF technology. This bass technology, in wide spread use today, revolutionized the way we think about high fidelity bass systems.

    Electronic Bass Trap

    In 2003 Bag End introduced another ground breaking technology, based upon the patent of Dr. Reza Kashani, an electronic bass trap. The Electronic bass trap known as the E-trap is an acoustical device independent from, and not connected to, a sound system. It is a very powerful tunable low frequency acoustic absorber making it an extremely useful tool in small room acoustics.
