Atlanta - Atlantic Technology is going to the Expo to demonstrate a prototype bookshelf speaker incorporating H-PAS (Hybrid Pressure Acceleration System) bass technology, which delivers targeted bass performance with 50 percent smaller cabinets, smaller drivers and lower costs, the company said.
It will join an existing H-PAS floorstanding model.
The prototype AT-2 is only an 8.75-inch-wide by 15 5/8-inch-high by 12.25-inch deep, yet with an interior acoustic volume of less than 2/3-cubic foot, it delivers bass response down to 39Hz at -3dB, the company said.
"H-PAS allows exceptionally deep bass response with very low distortion relative to speaker size," the company said. "The H-PAS-enabled low frequency reproduction is notable for its power, clarity and impact, with none of the often muddy, indistinct mid- and lower-bass anomalies that characterize many other designs.
The bookshelf speaker features single 5-1/4-inch long-excursion woofer and the same 1-1/8-inch Low Resonance Tweeter used in the AT-1. Its crossover frequency of 2,100 Hz is much lower than most conventional two-way speakers to deliver much wider horizontal midrange dispersion.
Atlantic Technology expects to begin production early in 2011 and plans to license out the technology.
H-PAS was designed to break what the company calls "the iron law of loudspeaker design," which among other things, states that among three major goals of speaker design - deep bass extension, a compact enclosure and good efficiency - speaker designers must choose two at the expense of the third.
H-PAS combines elements of bass reflex, inverse horn, and transmission-line speaker technologies to pressurize and accelerate low frequencies, the company explained.
