Atlantic Technology Shipping AT-3 Tower Speaker

All-new 2-way tower is designed with the company’s H-PAS technology in a cabinet size 25 percent smaller than the AT-1.

Atlantic Technology is now shipping its next generation AT-Series tower speaker, the AT-3. This 2-way speaker is the improved successor to the AT-1. Like the AT-1, it incorporates Atlantic Technology’s H-PAS technology for enhanced bass performance, yet its cabinet size is 25 percent smaller. The AT-3 is available at $3000 a pair (MSRP).

In 2011 Atlantic Technology introduced its patented bass system called H-PAS (Hybrid Pressure Acceleration System), breaking the conventional “Iron Law” of speaker acoustics that you can’t have deep bass and good sensitivity in a reasonably sized enclosure.

H-PAS has a proprietary cabinet design that directs the woofer’s back wave through an internal inverse horn structure for a continuous compression of the back wave and couples it to an acoustic bass trap chamber. The chamber expands the effective enclosure volume at low frequencies, filtering out parasitic resonances and distortion to clarify bass exiting the front cabinet port. As a result, the AT-3 delivers extended deep bass at high output levels with low harmonic distortion.

The AT-3 uses a new, lightweight, high-resonance 6.5-inch woofer. This driver features a lighter, rigid, concave formed fiberglass cone with greater uniformity, continuity, and reduced cone breakup possessing an instant, pulse reaction and unmatched transient response for improved clarity and lower distortion. The driver’s inherent fast transient response reacts and stops 3 to 5 times faster than slower, heavier, low-resonance drivers. The net result, along with H-PAS, is bass that extends to 29 Hz (–3 dB) at Sound Pressure Levels that exceed 106 dB and Bass harmonic distortion is under 3 percent.

High-frequencies are handled by a new 1-inch liquid cooled silk dome. The crossover frequency is lower than a typical 2-way speaker. The foam tweeter “frame” ensures uniform dispersion, response smoothness and tonal balance (with or without the grille attached) for better imaging and a more enjoyable listening experience.

Many additional high-quality details make the AT-3 a perfect fit for a high-end audio system. Heavy-duty cast iron feet with adjustable spikes are included to solidly couple the speaker to carpeted flooring and optional rubber feet are provided for hardwood floors. Gold-plated binding posts can accommodate heavy-gauge cable or banana connectors, plus there are removable terminal straps for bi-wiring. Wire management for the cabinet back are included for an uncluttered installation.
