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. 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.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.
