There’s many ways to define efficiency and in the case of Atlantic Technology’s new Hybrid Pressure Acceleration System (H-PAS) design, the word can be applied to more than how easily the speaker converts amplifier power into sound.
The Boston-based company kicked off the 2009 CEDIA Expo by introducing the technology, which Atlantic Technology’s president and founder Peter Tribeman described as a breakthrough that can be applied to everything from computer speakers to freestanding speakers.
“This technology is scalable ... you can use it to build everything [including subwoofers,” says Tribeman.
“The real benefit of H-PAS is at about 65Hz on down. We take out the resonances of the drivers and the cabinet and all you hear is the fundamentals [of the notes].”
Tribeman explained the H-PAS as a combination of several designs that’s highlighted by the use of special algorithms that were applied to speaker enclosure designs.
“There is no special crossover, it’s all in the cabinet,” he notes.
Tribeman recalled the initial idea for H-PAS had come from his colleague Philip Clements of Solus/Clements Loudspeakers who had shown an early version of the design years ago during a consumer event.
Clements says that it’s important to note that the technology’s affect on music and movie playback benefits more than just low frequency extension.
“The greatest advantage [of H-PAS] in my opinion is not [low frequency] extension, it’s its dynamic extension,” he says.
“Dynamic range has been the weakest link of loudspeakers for years.”
