Atlantic Technology AT-3 with H-PAS Technology
Atlantic Technology introduced a unique, patented design for a game-changing bass system called H-PAS in 2011, 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 unique, proprietary internal cabinet design where the woofer’s back wave travels through an internal multi-compression chamber with an inverse horn structure for a continuous compression of the bass wave and couples it to an acoustic bass trap chamber. Now, the next generation is here!
The AT-3 is the improved successor to the acclaimed AT-1 featuring refinements developed since the first generation resulting in a floor standing speaker with the same head shaking deep bass from a cabinet 25% smaller than the AT-1. Improvements in the AT-3 include a new computer optimized internal cabinet design for a rigid, inert structure without restricting the critical internal airflow that’s key to H-PAS. All new drivers and crossover components are housed in an elegant curved cabinet with a beautiful metal-flake, hand polished gloss-black fine furniture finish.
High-frequencies are delivered by our new 1-inch liquid cooled silk dome with speed and quickness for an outstanding transient response. The crossover frequency is lower than a typical 2 way speaker which blends the tweeter perfectly with the woofer to give the system a top-to-bottom transient response that belies its price. Driver alignment and positioning is optimized with the lower crossover frequency with its symmetry and phase contributing to the speaker’s wide horizontal dispersion. The parallel second-order crossover uses components of the very highest quality and adheres to strict 1% component value tolerances to ensure the best sound possible.
The back panel has a three position switch to change the relative output level of the tweeter to compensate for different room acoustics and personal taste. The +/- positions subtly adjust the tweeter output by very slight amounts over its operating range from 2 kHz to 20 kHz. These positions change the speaker’s spectral balance by adjusting the proportion of treble to bass over a wide frequency band.
The AT-3 is a speaker of extraordinary high performance and is intended for use in top-shelf music or home theater systems. Additional high-quality details make the AT-3 a perfect fit for a high-end audio system.
Heavy-duty cast iron feet with spikes are included with the AT-3 to solidly couple the speaker to carpeted flooring. Adjustable spikes allow the speakers to be leveled and optional rubber feet are also provided to protect hardwood floors and provide a solid, vibration-free foundation.
Gold-plated binding posts are made to accommodate heavy-gauge cable or banana connectors.
Plus removable terminal straps allow for bi-wiring or bi-amplification when ultimate performance is the goal.
Sold individually and available in Gloss Fleck Black.
