Atria II
Rockport Technologies is proud to announce the Atria II as the successor to our acclaimed Atria. While maintaining the elegant form of its predecessor, the Atria II establishes an entirely new level of musical realism.
Capitalizing on the benefits of our new waveguide mounted beryllium tweeter, we have completely redesigned the crossover in the Atria II to create a fundamentally transformed loudspeaker. The Atria II also uses our latest generation of custom, carbon fiber sandwich composite cone drivers designed and developed from the ground up by Rockport Technologies.

Both the bass driver and midrange driver utilize a revolutionary new carbon fiber fabric in their cone construction that further increases the stiffness/weight ratio of the cones, ensuring pure pistonic behavior throughout their entire operating range. The midrange and bass drivers also feature newly designed cone profiles as well as state of the art, ultra-linear, high-power motor systems. The result is vanishingly low distortion, incomparable resolution, and enormous dynamic range.

The Atria II’s triple laminated, constrained mode damped enclosure boasts a solid 4 inch thick front baffle and variable section thickness (up to 2½ inches thick), curved side panels which not only create an elegant form, but also endow the enclosure with immense stiffness and minimum resonant signature. The Atria II’s enclosure also features large sweeping chamfers and ever changing baffle dimensions that virtually eliminate diffraction anomalies. Visually stunning, the Atria II’s raked back form and high gloss piano black finish are commensurate with its remarkable sound.
One of the most important design considerations for the Atria II was that it would play music with a far greater sense of scale and ease than one would ever expect for a loudspeaker of this size. We’re extremely pleased that we’ve met or exceeded all of the design goals for the Atria II. And, while it was designed to work well in smaller rooms, make no mistake, the Atria II is a lionhearted speaker that surprises on every level.
