## Overview

The Atlantic Technology AT-2-S-GLF bookshelf speaker redefines compact audio with its patented H-PAS system, delivering deep 44Hz bass at over 103dB SPL with less than 5% distortion. Featuring a 5-1/4" graphite-loaded woofer and an advanced low-resonance 1-1/8" tweeter, it offers audiophile clarity and customizable high-frequency output via a 3-position switch. Finished in luxurious gloss black metal-flake paint and equipped with bi-ampable 5-way binding posts, this speaker blends cutting-edge acoustic engineering with elegant design for professional-grade sound in a compact footprint.

## Description

Product Description 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) 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. Using a unique cabinet design, the AT-2 utilizes a 51/4-inch driver in an enclosure of approximately .6 cubic feet to produce bass that extends to 44 Hz (-3dB) at Sound Pressure Levels that exceed 103dB. Bass harmonic distortion is under 5 percent. The AT-2 is finished in a gloss black metal-flake paint, applied in a multi-coat process and hand polished for a luxurious appearance. A 3-position High Frequency Energy switch is included, as are high-quality dual 5-way binding posts, to allow for bi-amplified operation when ultimate performance is the goal. There is a 1/4"-20 threaded insert on the bottom panel for secure attachment to speaker stands. From the Manufacturer 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. Exceptionally advanced Low-Resonance Tweeter and patented H-PAS bass technology Heavy-duty, bi-ampable 5-way binding posts and 3-position High Frequency Energy switch A Better Way to Generate BassUsing a unique cutaway 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. Bookshelf and bass, no longer mutually exclusive 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.Design DetailsThe AT-2 utilizes a 5-1/4" driver in an enclosure of approximately 0.6 cubic feet to produce bass that extends to 44 Hz (-3dB) at Sound Pressure Levels that exceed 103dB. Bass harmonic distortion is under 5 percent. Comparable performance in a conventionally-designed loudspeaker would require bass drivers of at least triple the size in an enclosure at least twice as large. The AT-2 also uses an exceptionally advanced 1-1/8" Low-Resonance Tweeter (LRT) that affords a lower crossover frequency (2200 Hz) than is normal in a two-way system. The result is exceptionally wide dispersion through the midrange without the upper-midrange "beaming" normally exhibited by woofers in a two-way speaker. The tweeter's oversized 4mm textile surround--rarely, if ever, found in a tweeter--allows for long excursion and very high power handling. As innovative as the H-PAS design is in the bass region, the AT-2's tweeter is equally impressive in the higher ranges. This is a total loudspeaker system of amazing capability and accuracy. All the crossover components are the very highest quality, and adhere to strict 1% value tolerances, to ensure the best sound possible.Finish and FeaturesThe AT-2 is finished in a gloss black metal-flake paint, applied in a multi-coat process and hand polished for a luxurious appearance.

Review: Excellent highly accruate audiophile speakers at great price. - These speakers use a very unique patented concept to create low frequency accurate base from a small speaker. Notice I said low frequency, not deep as in not loud. Most speakers distort up to 10% the bass, more distortion as it gets to lower and lower frequencies. This speaker uses a new concept, the inverse horn, which uses the energy inside the speaker to accelerate and magnify the bass frequencies. It has a vibration chamber and that excites certain frequencies, and pushes them into a narrower and narrower horn, then out the port at high speed. It's called HPAS, High Pressure Accellerated Sound I think. Unlike the physics though settled with other speakers, with this speaker, the deeper the bass, the LESS distortion is produced. Also, the lower demands on the mid-range/woofer allow it to work in an area of non distortion since it's the reverse side that's pushing all the air through the reverse horn. . Most speakers distort when they are forced to drive frequencies not in the part of their linear frequency response. How does this translate into your sound. For me, words that I might not hear clearly with other speakers, I can hear pronounciation much clearer.
Review: Great speakers - I purchased these speakers when they were priced at $900 each. I have no idea how they are being sold here at this lower price. They are wonderful speakers, well worth what I paid for them. And great on the WAF (Wife Acceptance Factor).
