CEDIA News: Atlantic Technologies and Solus/Clements Team-up to Develop HPAS Bass Technology

By September 9, 2009

HPAS Bass Technology, demonstrated this morning at CEDIA 2009, is targeted to achieve deeper, low-distortion bass from smaller cabinets and drivers. The demonstration was conducted by Peter Tribeman from Atlantic Technologies (in photo) and Philip Clements of Solus/Clements Loudspeakers, both veteran speaker manufacturers who are collaborating in developing HPAS. Although still in the final stages of development, the HPAS bass demo was convincing, producing dynamic, deep bass (with no subwoofer) from two 4.5" drivers in a tower enclosure measuring 40" high.

The secret of HPAS is the cabinet design, which is a combination of acoustic suspension, inverted horn and bass reflex speaker designs all wrapped up in one enclosure. Their was even a presentation of the mathematics that went into the design, but most of the equations were way over my head. The system was driven by an Outlaw Audio RR2150 stereo receiver with 100-watts x 2. The HPAS system is scalable from large speakers to bookshelf-sized models and has been licensed to six speaker manufacturers whose names were not disclosed. Atlantic plans on introducing speakers with HPAS technology later this year. More info as it becomes available.
