Patented sound system processor used in RIVA's award-winning Bluetooth speakers creates a broad sound field from a compact system

FOUNTAIN VALLEY, CA.,December 22, 2015: Audio Design Experts, Inc. (ADX™), recognized for its best-in-class audio products and the parent company of lifestyle brand RIVA Audio, announced today the issuance of a patent by the U.S. Patent and Trademark Office ("USPTO") for its Trillium™ sound system processor that creates a broad sound field from a compact multi-speaker.

The patent for invention #9,197,963 B1 covers Trillium™, the innovative audio technology that separates RIVA's Turbo X and S premium mobile speakers from other products in the wireless category. The proprietary process up-mixes the left-right stereo signal and outputs it through three channels of amplification and seven transducers to create a stereophonic image that sounds much larger than the actual speaker size would indicate. The sound system processor creates a broad sound field by directing the appropriate signals to the three active speakers placed on the left, center and right side of the cabinet. The output of these three speakers allows the sound to mix in-air to create virtual left and right speakers outside the enclosure, giving the user a more natural presentation.

The processor further augments the low frequencies of the speaker with signals for four passive radiators: two located on the front and two on the back, which offer additional depth and impact to the music. The symmetrical arrangement balances the speaker's vibrational forces to prevent the resonances that might color the sound, while also preventing unwanted speaker movement. And thanks to the unique Trillium™ processor, the RIVA Turbo X and RIVA S speakers do not exhibit off-axis comb filtering, thus providing a wider listening area with smooth, crystal clear sound, even at high output levels.

"Trillium™ is an example of RIVA's imagination and innovation to revolutionize the wireless speaker market and challenge the preconceived notions of what a Bluetooth speaker can be." said Donald North, President and Chief Engineer of RIVA Audio. "More than just small, portable boxes, RIVA's speakers are made to truly expand the musical sound field and provide the user with a more natural listening experience."

With over 100+ years of combined experience, the ADX™ team has decades of accumulated industry knowledge related to design, materials, production techniques, construction, marketing, service, and sound. The audio engineers of ADX are the original innovator of the #1 selling sound bar in the U.S., developed the top three rated sound bars in America as reported by a major consumer magazine, and hold world record titles for dB Drag Racing for the Pro 1001+, at 164.9dB and the Pro 1001+ at 169.4dB. Through their lifestyle brand RIVA Audio, ADX™ has won additional accolades from CNET, Digital Trends, Sound &Vision, Mashable, Home Theater Review, Consumer Electronics, and Innovation & Tech Today. To date, ADX™ has been awarded nine patents and additional patents pending in the audio field bolstering the company's ability to deliver innovative audio technology.
