Design and technology
The Diesis Aura speaker inherits the advantages of innovative technologies from previous experiences, housed in a cabinet of reduced weight and dimensions that allows it to maintain the same sound qualities as the flagship model by Diesis, even in smaller spaces.
The painstaking construction, cutting-edge design approaches, and the selection of the finest materials and components available allow the Diesis Aura to be an absolute reference for realism, dynamics, transparency, articulation, coherence, and engagement.
The supporting structure is also made of CLAD 58 covered in exquisite eco-leather. For the low-frequency range, the same 12-inch woofer, cut at 200 Hz, has been adopted. For the mid-bass frequencies, a 10-inch transducer is used without limitations in the low range and is cut at 1800 Hz to ensure a precise and natural crossover with the high frequencies, where a one-inch compression driver is employed. This compression driver is made using the same technology and materials as the Caput Mundi, making it instantly recognizable.
At low frequencies, the speed in the exponential horn is specially designed by Diesis Audio for this model, allowing excellent off-axis dispersion. The crossover filter, with a different cutoff compared to the upper model, utilizes the same extraordinary components and top-level capacitors customized to our specifications, as well as pure copper coils with extremely low resistance in series with the signal.
It is a 2-way + 1 system achieved by adopting three speakers and utilizing the Double-Bass technology. This involves using two different speakers within the same cabinet (hence why it cannot be referred to as a 2.5-way system) without any high-pass filter (hence why it cannot be referred to as a 3-way system). However, with precise selection of their parameters and filter design, it allows combining the qualities of a large woofer necessary for proper crossover with the horn.
