A closer look at the Auditorium
The Auditorium (left) is certainly not small. However, it appears almost modest compared to the enormous Atriums.
Above and below: Clarisys Audio makes no secret of the fact that its designs are originally derived from classic Apogee models. For instance, the Auditorium was inspired by the Full Range. Although the basic magnetostatic principles remain similar, Clarisys Audio implemented improvement upon improvement with every new incarnation. The upside of this approach is clear, even if the consequence is that an early Auditorium model is no longer fully representative of current performance levels. On the other hand, the speakers’ modular design often allows upgrading a model to a later spec.
These back-panel photos of the Auditorium’s CNC-milled aluminum panels illustrate perfectly just how thoroughly they deviate from the original MDF-backed Apogee designs.
Besides looking fascinating, the construction is designed so that the entire backpanel and magnet structure can be removed while leaving the ribbons in place. This way, a speaker can easily be repaired or upgraded in the field. Invisible in these pictures is another change Clarisys Audio made to the original designs, concerning the infamous deteriorating damping foam. Current refurbishment jobs by Graz-approved installers use foam that is said not to deteriorate. Clarisys Audio does away with foam altogether and applies piano felt, as used in a Grand Piano.
The pure aluminum ribbons are vertically suspended between left and right rows of Class N52 Neodymium magnets. These magnets are used on all Clarisys Audio models. Copper foil wiring is used throughout for the internal connections.
One of the Auditorium’s defining features is the dual pure aluminium bipole ribbons for both midrange and high frequencies. These custom-engineered drivers are mounted in a back-to-back, in-phase configuration, creating a true bipole radiation pattern from 250 Hz upward. This is the case for all models, including the Studio Plus and upwards.
Brand New: Aria
The Aria is the latest model that can be seen as a more sensible descendant of the Atrium. At the heart lies the Clarisys Audio signature dual pure aluminium midrange/treble ribbons, operating in a true bipole configuration. These full-length, back-to-back ribbons begin at 275 Hz and radiate in perfect phase. Each of the Aria’s bass towers employs the latest-generation curved ribbon panel, which minimizes panel resonances and controls modal behavior. The two towers are connected via external crossovers engineered for ultimate purity and flexibility.
With a more modest height, four towers instead of six, but with its double foils inherited from the Auditorium, the Aria could be very special.
I love how Clarisys Audio lays out its technology in the open so you can see exactly what’s inside, while maintaining a curvaceous, artful appearance.
