Atlantic H Pass Technology
An Atlantic Technology technical expert talks how H-pass technology has broken through the glass wall of sound acoustics. H pass technology has deep bass in a smaller system cabinet. Check out the video for more information.
Building on the incredible success of the highly acclaimed AT-1, the compact AT-2 delivers a level of deep bass performance not previously attainable from a bookshelf-sized loudspeaker.
The AT-2’s patent-pending H-PAS™ bass system (Hybrid Pressure Acceleration System) is the reason. It combines elements of several speaker technologies— bass reflex, acoustic suspension, inverse horn, and transmission line—in a unique configuration to deliver powerful low frequency response that breaks the “Iron Law” of loudspeaker acoustics: the notion that you couldn’t have deep bass extension, good system sensitivity, and reasonable enclosure size all in one design. H-PAS changes all that.
- Atlantic's Patented H-PAS technology ensures extended, dynamic bass.
- Exclusive Low Resonance Tweeter for wide dispersion
- Compact cabinet fits perfectly on bookshelves.
- Dual 5-way binding posts for hookup flexibility. Looking at you, Audiophiles!
Using a unique cabinet design, the elements of the combined speaker technologies are cascaded one to another in such a manner as to pressurize and accelerate the low frequency backwave as it travels through the cabinet. The internal matrix of the cabinet captures the backwave of the driver below its resonance and pressurizes and accelerates it before it exits the vent. The internal workings of the cabinet are such that the low frequency efficiency of the system actually increases with decreasing frequency—exactly the opposite of conventional system behavior, where output below resonance drops rapidly. The cabinet produces a reciprocal output of the driver’s natural roll-off, yielding flat acoustic response to well below that of conventional designs using like-sized drivers and cabinets. H-PAS does not require the use of special drivers, any kind of on-board electronics or outboard equalization. It is a purely passive system, completely compatible with all stereo amplifiers and AV receivers. In addition, the low frequencies travel through an internal passive resonance/harmonic distortion line filter to further clarify the sound. As a result, the H-PAS design delivers extended deep bass, with high output levels, and exceptionally low harmonic distortion.
