High Definition Sound Standard (HDSS®) is the most revolutionary development in sound reproduction this century. Products containing the HDSS® logo deliver a natural and pure sound so clear that Edward Raithel of Cobb County, GA, who has been blind and deaf since childhood, was able to hear sounds denied to him since he was a toddler.
Since the invention of the modern loudspeaker in the 1920’s, designers and engineers have struggled to make a speaker that reproduces a sound that comes close to the original sound quality. Trying to develop a driver capable of handling the whole audio spectrum within a small cabinet remained unresolved until Jan Plummer, president of TBI Audio, invented the Embedded Transmission Line (ETL).
Sound systems tend to emit distortion. With today’s need for compactness, the challenge of designing a smaller speaker cabinet poses a problem for audio engineers. As speaker- size diminishes so does its ability to reproduce low-frequency signals. Other ranges are also negatively impacted by the lack of space needed for sound waves to complete their cycles. The result in most cases is distortion.
Many companies are using electronics to lessen the distortion. According to Sherwin Greenblatt, retired CEO of Bose, “…To a large extent, in the audio field, consumer electronics is computers. So, if you look inside a modern Bose product, it's actually a computer…” Forward looking companies using HDSS® avoid this computerized sound.
Sharp, Marantz and other companies are currently using ETL in their audio products. It is unprecedented for well-known leaders in the audio industry to use the technology of another loud speaker company. Perhaps that is why companies are lining up to sign licensing agreements to make sure they are not relegated to obsolescence.
ETL technology, marketed as HDSS®, is making a wave that is drowning the competition with natural sound—the music consumers want to hear.
