Atlantic Technology Now Shipping AT-Series Tower Speaker

Atlantic Technology is now shipping its AT-Series tower speaker, the AT-3. This two-way speaker is the 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% smaller. H-PAS has a proprietary cabinet design that directs the woofer’s back wave through an internal inverse horn structure for 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 the 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 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 lightning-fast transient response reacts and stops three to five times faster than slower, heavier, low-resonance drivers. The net result, along with H-PAS, is bass that extends to 29 hertz (-3 decibels) at Sound Pressure Levels that exceed 106 decibels and bass harmonic distortion is under 3%.

A new 1-inch liquid-cooled silk dome handles high frequencies. The crossover frequency is lower than a typical two-way speaker blending with the woofer to give the system a top-to-bottom transient response that belies its price. 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.

The woofer-tweeter alignment combined with the low crossover point for a two-way speaker, with its symmetry and phase characteristics, provides side-to-side lateral dispersion, enhancing stage depth and imaging while reducing unwanted floor and ceiling reflections for the cleanest, most coherent sound.

The parallel second-order crossover uses components of the very highest quality with 1% value tolerances to ensure the best sound possible. The back panel’s three-position switch changes the output of the tweeter to compensate for different room acoustics and personal taste.

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 is included for an uncluttered installation.
