The Product

The Electro-Voice SX300E is a 300 watt, 12 inch two-way, high efficiency, constant directivity portable speaker system. Through the extensive use of computer aided design and modelling, EV engineers have developed a state of the art professional loudspeaker system. Its performance and physical design make it perfect for many applications requiring quality sound in portable and fixed environments. The high frequency section utilizes a molded 65° x 65° constant directivity horn. This unique pattern contributes to high intelligibility where vocals sound natural yet cut through in reverberant and noisy rooms. Coverage pattern is uniform and sound quality off axis is very well maintained, even at 45°. The horn’s unique VaripathTM throat geometry helps driver output to penetrate to the corners of a room, areas which are not described in the usual specifications of horizontal and vertical coverage angles. This results in more uniform coverage throughout, even to those parts of the audience that typically do not receive the strongest coverage. The high frequency horn is driven by the DH3, a one inch, wide bandwidth, titanium diaphragm driver using a unique, convex drive TimePathTM phasing plug structure for smooth and extended high frequency response.

The Manufacturer

Electro-Voice had very humble beginnings when in September 1927, Lou Burroughs and Al Kahn began a small business servicing radio receivers in South Bend, Indiana. As a consequence of the Great Depression, they soon found themselves insolvent owing $5,000. This provided enough of an incentive for them to move their business in the direction of audio products, and in June 1930, they incorporated their business under the name Electro-Voice. At the time both Burroughs and Kahn felt that microphone designs around were of poor quality and over priced so they purchased a lathe and a drill and started producing about one microphone a week. Not long after Burroughs left the business, leaving complete ownership to Kahn. By 1933, the previous business debts were completely paid off and Electro-Voice began hiring employees to help in the production of the new designs. In 1936, twenty people were hired and Lou Burroughs returned as chief engineer.

Throughout the 40s, 50's and 60's Electro-Voice continued to grow and innovate producing a variety of products such as phonograph pickup cartridges and the first automatic TV booster. Loudspeakers and microphones joined their portfolio and with the brand gaining popularity and respect in the music industry Electro-Voice was established as a household name. In 1998 EV merged with equipment manufacturer Telex Communications, then in June 2006, EV, along with all of Telex Communications, became part of Bosch Security Systems division. Today EV is highly respected and continues to manufacture widely used broadcast microphones as well as loudspeakers and various other professional audio equipment.
