Since 1968,

offering the many gifts of music… and of sound with sight… enjoyed by all, all of the time

through innovative, knowledgeable, high value, high-fidelity A/V system designs.

The ONLY accurate way to enjoy the audio of video programing

because it alone solves all of the inherited problems ALL other A/V speaker arrays have.

This picture is of the front set of the in-wall speakers that constitutes part of the SeriesX Certified speaker array design.


The remained speakers are in-ceiling side and rear speaker systems.

The problem with all other surround sound speaker systems - their heritage.


The History Lessons Forgotten


    First was stereo — two channels, it was very good.

    Then came “quadraphonic” (until Quad, the manufacturer of audio equipment in England, got upset and threatened to sue) that became just multi-channel.  David Hafler of Dynaco came up with the Quadaptor that worked great!  So far, so good; then came the marketers.

    Then came the add-on subwoofer — you notice that I did not write “subwoofers”.  Back then, it was so big that the marketers felt that people would put up with only one and they made a big deal that low frequencies are omnidirectional, so you only need one — wrong on two points.  To prove that this marketing claim is wrong go to any store that sells subwoofers.  Ask the salesperson to turn off everything except the subwoofer.  Then, while listening to music: close your eyes, turn around, stop, and try to point toward that one subwoofer.  You’ll be able to because they are directional, so where they’re placed and how many are important.

    Then came the add-on, single, different, small center channel speaker where most of the sound you listen to comes from.  Three more problems here: the small speaker limits the quality of the sound, the different speaker does not correctly integrate with the front speakers, and the single speaker places the sound in the wrong position wherever it is placed.

    Then, came the add-on, small, rear speakers that have the same first two problems as the center speaker.

    Then, came the add-on, tiny front, center, and rear speakers that exaggerates the integration problem.


The History Lesson Learned


The senior designer sold audio equipment through all of these stages of add-ons and knew of the limitations.  One day, he decided to try to solve all of these inherent problems that all surround-sound speaker systems have and he did, thus the birth of the SeriesX speaker systems, and then the creation of the SeriesX Certified speaker array design that uses available components done right.  


The research, testing, and calibration laboratory that helped us develop the SeriesX Certified speaker array design, and lets us find the best value products and calibrate our systems.

A list of the improvements that a SeriesX Certified speaker array  design has over all others is listed below.


P.S. The "X" in the SeriesX name does not stand for how many improvments there are to using this array of speaker systems, although it should  be a reminder.  It stands for the roman numeral X that stands for 10 - the minimum number of individual speaker systems needed to successfully create an accurate surrounding sound field: six full-range and four subwoofers.
