Peter Tribeman's voice dropped to a whisper as he gave me the word a few weeks ago about a bass-related technology that will figure prominently in Atlantic Technology's exhibit at CEDIA. Atlantic will license the H-PAS (Hybrid Pressure Acceleration System) technology from inventor Philip Clements of Solus/Clements. As chronicled in this press release, it will combine bass reflex, inverse horn, transmission line, and a resonance/harmonic filter, all with no active electronics or special drivers. CEDIA-goers will hear (we are told) two 4.5-inch drivers in a 1.4 cubic foot enclosure produce bass output of 105dB down to 29Hz, +3dB, with bass harmonic distortion under three percent. Said Tribeman: "Until now, I would have considered it virtually impossible to achieve such high levels of bass performance and quality in such small enclosures.... This new system is the first ever to break the famous Iron Law of loudspeaker design, which states: 'deep bass extension, compact enclosure, or good efficiency...pick any two at the expense of the third.' For the very first time, due to Phil Clements' breakthrough design, we can have them all." The first product to ship will be the H-PAS-1 floorstanding speaker in the fourth quarter. Another 6.5-inch tower and bookshelf model will follow next year. Pricing TBA. We can't wait for the pre-show demo.
