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.

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.

From the penthouse suites we descend to the 29th floor, where the first system I ran into was the three-way, three-driver (beryllium tweeter, carbon-fiber midrange, carbon-fiber woofer), $26.5k Rockport Technologies Atria IIfloorstander in a raked, ported, triple-laminated, constrained-layer-damped enclosure. Driven by Nagra’s Classic INT integrated (Nagra had a particularly good show), sourced by AMG’s V12 turntable with AMG 12JT “Turbo”tonearm and a DS Audio DS 002 optical cartridge (with DS 002 phonostage), the Atrias were simply superb on The Band’s “King Harvest” [MFSL]—vocals, bass, guitar, piano, organ, everything. I didn’t really like the original iteration of the DS Audio optical cartridge, but this one! Folks, the way it separated out and resolved Richard Manuel and Levon Helm’s harmonies on the choruses of “King Harvest” simply had to be heard to be believed. Both singers were so clear, distinct, and lifelike it sounded as if they were separately miked and equally mixed. The entire system provided superb delineation of detail without any loss of color or thinning down of the power range and bass, and with a spaciousness—on The Weaver’s “Goodnight Irene,” for example—that the original DS Audio cartridge could only have dreamed of supplying.
