Atlantic Technology - AT-2 with H-PAS Technology

	The AT-2 Bookshelf Loudspeaker Full-range sound from under 16 inches! How do you follow up the most highly-reviewed product in your company's history? Introducing the AT-2. The compact AT-2 speaker delivers a level of deep bass not previously thought possible from a "bookshelf"-sized speaker. The AT-2's patented H-PAS bass system (Hybrid Pressure Acceleration System) is the reason. It combines elements of several speaker technologies--acoustic suspension, bass reflex, 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.

Connectivity

	The AT-2 uses the highest-quality gold-plated 5-way binding posts to ensure the best connection possible. Dual sets of posts are provided to allow for bi-amplification, when the very highest quality installation is desired. In addition, a 3-position tweeter level control makes it easy to adjust for different listening room acoustics or personal preferences.


Aesthetics
The curved side panels are finished in a luxurious gloss black paint with subtle metallic flake highlight, applied in a multi-coat process and hand-rubbed to a lustrous shine.

The H-PAS vent at the bottom of the cabinet is precisely calculated to be a certain percentage of the driver's total radiation area. About 6 inches deep into the cabinet from the opening of the vent is a cross-hatched metal "debris guard" that prevents small objects from entering the speaker.
Quality Materials, Innovative Design
	The crossover in the AT-2 uses the best components available (1% tolerance), hardwired on custom-tooled epoxy boards. Lesser speakers traditionally use 10% tolerance components hand-wired on masonite boards.

	The AT-2's innovative tweeter is a complete "system" onto itself. An oversized 4mm treated textile surround (rarely found on any tweeter, at any price) gives this transducer exceptional excursion, which facilitates its low 2kHz crossover frequency. An integral aluminum back chamber reduces the tweeter's resonant frequency to 700Hz The aluminum rear chamber also functions as a massive heat sink that allows for a greatly increased voltage drive through the HP x-over section, for great power handling and extended output levels.

	A convenient wire management system ensures a neat installation, and allows for the use of virtually any cable imaginable. Note the leather-grained surface, which is present on the rear, top and front baffle section (behind the grille).
