Diapason Didascalia – Italian Craft Meets Acoustic Precision
At the Audio Video Show in Warsaw, Diapason revealed the Didascalia – a two-way floorstanding loudspeaker that embodies the spirit of Italian sound culture. Developed by Paolo Tezzon and Alessandro Schiavi, it combines hand-crafted design with cutting-edge electroacoustic research. The result is a loudspeaker built to convey music with natural timbre, emotional intensity, and spatial realism.
- Diapason Didascalia – two-way Italian floorstanding loudspeaker combining artisanal woodwork and advanced acoustic engineering. Designed by Paolo Tezzon and Alessandro Schiavi for natural, precise, and emotionally engaging sound reproduction.
Few countries embody the connection between aesthetics, emotion, and technology as completely as Italy. With the new Didascalia, Brescia-based manufacturer Diapason presents a loudspeaker that unites these values in a striking form. Conceived by Paolo Tezzon and Alessandro Schiavi, two names closely associated with the “Italian School of Electroacoustic Design,” the Didascalia translates decades of craftsmanship and acoustic research into a modern high-end statement. The speaker aims to combine natural musicality with structural precision – a harmony of form and function reflecting Diapason’s enduring philosophy.

The Italian School of Electroacoustic Design
The Didascalia pays homage to the Italian School of Electroacoustic Design – a philosophy emphasizing musical naturalness, dynamic balance, and emotional communication. While two-way designs traditionally aim for purity and coherence, Diapason’s engineers have extended these virtues with modern acoustic solutions for deeper bass extension, resonance control, and spatial accuracy.
Cabinet and Aesthetic Engineering
Each Didascalia is hand-built in Italy, its enclosure crafted from carefully aged and vacuum-dried walnut sections bonded with viscoelastic compounds for resonance suppression. Alternatively, a lacquered version uses a layered HDF-and-Tulipwood sandwich. A CNC-milled aluminium exoskeleton frame reinforces the structure and dissipates vibrations. The cabinet surface is polished in multiple stages, finished either in open-pore natural wood or mirror gloss. The result is a speaker that feels architectural yet organic – unmistakably Italian in design language.
Drivers and Acoustic Architecture
At the heart of the Didascalia lies a complex two-way design augmented by two side-mounted passive radiators. The 29 mm silk-dome tweeter, manufactured by Scan-Speak to Diapason’s specifications, employs a low-resonance aluminium chamber and a powerful neodymium motor for transparency and transient accuracy. The 180 mm mid-bass unit, with its hand-coated paper-nylon diaphragm and AirCirc neodymium system, is designed to achieve low distortion and high dynamic headroom.
Two 220 x 260 mm racetrack passive membranes extend the response down to 25 Hz. An electromagnetic brake system allows the listener to fine-tune bass damping in three steps, adapting to room acoustics and placement.
Mechanical and Temporal Optimization
The baffle, covered in Eco-leather, is shaped to align the acoustic centers of both drivers for time coherence. This yields a phase-stable soundstage with precise imaging, even at short listening distances. A newly designed spike system with elastomer damping decouples the speaker from the floor, reducing mechanical feedback and enhancing bass clarity.
Crossover and Internal Wiring
The crossover network is entirely hand-wired and symmetrically structured, using Jantzen Audio C-Coil inductors and Mundorf Supreme EVO Silver/Gold/Oil capacitors and resistors. This ensures a stable impedance curve and a neutral tonal balance. Internal wiring employs Van den Hul CS12 Halogen Free cables – a consistent choice for reference-grade transparency and reliability.
Price and Availability
The Diapason Didascalia is available now through selected high-end audio dealers at € 59.000,- per pair. Distribution in Germany and Austria is handled by IAD GmbH, while Pathos Audio Ineichen is responsible for Switzerland.
Conclusion – The Essence of Italian Loudspeaker Art
The Didascalia demonstrates Diapason’s mastery in merging craftsmanship and technology into a singular musical experience. It combines traditional two-way purity with innovative mechanical and acoustic refinements, producing sound that is transparent, natural, and emotionally involving. A loudspeaker created not merely to reproduce music, but to convey its soul.
