Atlantic Technology and Solus-Clements Introduce H-PAS Bass Technology

Atlantic Technology and Solus/Clements have joined forces to develop, market, and license a new loudspeaker design protocol capable of delivering deep, low-distortion bass response at output levels unobtainable through conventional bass-alignment techniques.

This technology will allow speakers with smaller cabinets and drivers to achieve levels of performance normally associated with much larger speaker systems. Proof of concept prototypes will be demonstrated at the CEDIA EXPO 2009.

The new patent-pending system, called H-PAS, (Hybrid Pressure Acceleration System), combines elements of several speaker technologies: bass reflex, inverse horn, and transmission line. Using a unique cabinet design, these technologies are cascaded to pressurize and accelerate low frequencies. The signals travel through a passive resonance/harmonic distortion line filter. The final result is the ability of an H-PAS design to deliver extended deep bass with exceptionally low distortion.

H-PAS does not require the use of special drivers or any kind of on-board electronics or outboard equalization. It is a purely passive system, completely compatible with all amplifiers and AV receivers. The inventor of the technology is Philip Clements of Solus/Clements Loudspeakers, a 30-year plus CE industry veteran and loudspeaker designer. For the past eight months, Clements has worked closely with Atlantic Technology to develop a range of compact designs using H-PAS protocols. Clements has contracted with, and appointed Atlantic Technology as the exclusive licensing agent for the technology, and will now continue its development with Atlantic.

The H-PAS demonstration model that will be on display at the CEDIA Expo utilizes two four-inch drivers in an enclosure of approximately 1.4 cubic feet to produce bass that extends to 29 Hz (-3dB) at Sound Pressure Levels that exceed 105dB. Bass harmonic distortion is under three percent.

"Until now, I would have considered it virtually impossible to achieve such high levels of bass performance and quality in such small enclosures," president of Atlantic Technology, Peter Tribeman, said. "With higher performance from smaller cabinets, and the potential for lower manufacturing and shipping costs, we believe H-PAS has applications in almost every corner of the loudspeaker business."
