Product Description

What are the essential elements that make something revolutionary? Truly revolutionary are things that have staying power and unfold with long-lasting impact – as opposed to those that create a short-lived, spectacular flash in the pan. That’s how we define a genuine revolution. It is the consequence of countless smaller evolutionary steps. AUDIO PHYSIC’s top model CARDEAS has managed to set a new standard in its class worldwide. To take something that is already excellent and still improve upon it, that is our motivation and the inveterate quest of our development team, thus we began making numerous tiny adjustments and refinements. Except for its outward appearance, there was “not one stone left upon another”. The newly-developed CARDEAS plus+ bears the “plus+” for good reason. The result: a revolution.

The CARDEAS plus+ is the foundation of all AUDIO PHYSIC loudspeakers in the REFERENCE line. In fact, we mean that literally. Just take the body with its rejuvenating side panels leading to the baffle, that avoid parallel planes; there is the curvature in the back; the slightly rear-tilted angle of the cabinet – painstaking design details that lead to vast stability and eliminate even the slightest possibility of any materials taking on a life of their own and impairing the sound.

The CARDEAS plus+ is now taking a decisive step even further. The cabinet not only continues to boast all its solid stiffening properties exhibited up to now, it also features an entirely new design on the inside. As we already saw in the very successful Plus+ versions of VIRGO 25 and AVANTERA, there are additional ceramic foam cabinet struts. This very stiff material has a porosity of more than 85%, which means the inner volume required for the lowest bass tones is hardly reduced. Due to their low mass, the ceramic foam elements retain hardly any energy and also dissipate it very quickly – before the cabinet body can begin building up any undesirable vibrations. The porous structure of the material means an enormous increase in the surface area. Even without the absorbing materials otherwise used, this reliably prevents cavity resonance.

The intelligent design factor of the CARDEAS plus+, combined with its cutting-edge mix of materials, guarantees the utmost in precision and freedom of distortion – from the softest pianissimo up to thundering volumes. This purity and signal fidelity have positive impact on the overall listening spectrum. There is no better working environment for the forward-looking HHC (hyper holographic cone) chassis, a proprietary development, with its unique architecture. As in all the models in the REFERENCE series, the tweeter is not directly connected to the baffle. Like the midrange drivers, it is uncoupled from the cabinet using an ingenious weave construction in SSC (“string suspension concept”) engineered materials. This prevents even the most delicate vibrations in the baffle from spreading to the membranes, and makes the rendering of even the finest musical intricacies seem second-nature. CARDEAS plus+ handles vibrations that spread over the connection cables directly at their potential source. The crossovers between mid-range drivers and tweeters are also uncoupled from the cabinet using SSC elements. In addition, the HHC high tweeter features state-of-the-art vibration-damping contacts. This manifests itself in even higher resolution and more authentic spatial definition.

In order to guarantee absolute signal fidelity in the vital mid-range, the interior walls of the sealed mid-range chamber – eliminating interactions with the other chassis via enclosed air volumes – features grid-shaped elements. Sound emitted by the membrane into the chamber interior is partially absorbed by it, and partially reflected diffusely, drastically reducing the energy impacting on the body and pushing back on the membrane. The result: mid-range performance of unparalleled clarity, absent of all lethargy, compression and embellishment.

The layout of the crossovers was further streamlined, the painstakingly-selected components satisfy the highest standards. Entirely new interior wiring provides for unprecedented homogeneity across the entire frequency spectrum of the CARDEAS plus+.

The lowest frequencies are handled by two especially long-throw, 10’’ woofers in a push-push arrangement, refined in many details, and geared towards bass-reflex coordination. They are located opposite one another in the flanks of the loudspeakers. This enables the CARDEAS plus+ to attain ultra-precise definition, even when the dB meter is barely showing a blip, independent of volume. And even for larger rooms over 40m², it offers the required boost of energy.

The significance of the terminals on loudspeakers is widely underestimated. They are the first point of entry, and if the signal is impaired at this point, the finest intricate details will be missing later. With its trusted Vibration Control Terminal, AUDIO PHYSIC impressively masters this phenomenon. In addition, the CARDEAS plus+ uses as standard WBT nextgen connectors in fine silver design. These fine silver connectors offer unique conductivity for vibration uncoupling, and they are immune to issues involving eddies or mass storage effects.

It is a variety of seemingly minute details, the sum of which afford the listener revolutionary sound performance. Discover the true noble elegance of a large concert grand piano, the unlimited dynamics of bombastic brass interludes or the finely-layered inner nuances of a harp solo. For the CARDEAS plus+, there is no limit, and the horizon opens up right into the heart of the music. Unlike any other loudspeaker, CARDEAS plus+ underscores the AUDIO PHYSIC motto: “No loss of fine detail”.
