    Made in USA - A Video Tour of Benchmark's Manufacturing Operations

    Since 1983, Benchmark products have been designed, assembled, and tested in the USA. Our products are now shipped to every continent, but we are firmly committed to keeping our manufacturing in the USA.

    In celebration of our 33rd anniversary, we have released a series of four videos that show our USA manufacturing operations. These videos show many of the operations required to build top-quality professional audio products. You will see automated hi-tech manufacturing equipment, but you will also see plenty of good old-fashioned hand craftsmanship.


    Watch us transform a solid bar of aluminum into a finished Benchmark faceplate


    Watch us transform raw sheets of metal into finished enclosures


    Watch as hundreds of tiny electronic components are accurately placed on circuit boards


    Watch the final assembly and test process


    We hope you enjoy these videos. If you would like to ask questions or make comments, we encourage you to post them on the Benchmark Media Systems FaceBook Page.

    Making Sound with Plasma - Hill Plasmatronics Tweeter

    by John Siau June 06, 2023 2 min read

    At the 2023 AXPONA show in Chicago, I had the opportunity to see and hear the Hill Plasmatronics tweeter. I also had the great pleasure of meeting Dr. Alan Hill, the physicist who invented this unique device.

    The plasma driver has no moving parts and no diaphragm. Sound is emitted directly from the thermal expansion and contraction of an electrically sustained plasma. The plasma is generated within a stream of helium gas. In the demonstration, there was a large helium tank on the floor with a sufficient supply for several hours of listening.

    While a tank of helium, tubing, high voltage power supplies, and the smell of smoke may not be appropriate for every living room, this was absolutely the best thing I experienced at the show!

    System Performance Calculations

    by John Siau June 03, 2023 13 min read

    If an audio system is composed of multiple components, we may have detailed specifications for each component, but we will not know the performance of the combined system without doing some calculations. You may have questions such as these:

    • Will my audio system produce audible noise?
    • Will my audio system produce audible distortion?
    • How will my audio components work together as a system?
    • How loud will my audio system play?

    Use Benchmark's online audio calculators to find answers!

    For example, if we know the output power of an amplifier, as well as the sensitivity and impedance of our loudspeakers, we can calculate the maximum sound pressure level that our system can produce.
