Piega Premium 801 Introduces Horn-Loaded Ribbon Tweeter to the Premium Series

Swiss loudspeaker manufacturer Piega SA, based on the shores of Lake Zurich, has built its reputation on ribbon driver technology and meticulously crafted aluminium enclosures. With the introduction of the Premium 801, the company expands its Premium Series with a model that introduces a new technical approach while remaining firmly rooted in Piega’s established design philosophy. Positioned between the Premium 701 Gen2 and the Coax Series, the Premium 801 targets listeners looking for advanced acoustic engineering combined with elegant, space-conscious design.

Key Facts

• First Premium Series loudspeaker from Piega featuring a horn-loaded ribbon tweeter
• Newly developed three-way architecture with revised crossover topology
• SSD ribbon tweeter combined with a horn for increased efficiency and controlled dispersion
• New 140 mm FSD midrange driver designed for improved linearity
• Four 140 mm FSD bass drivers for higher output capability and deeper bass extension
• Aluminium extruded enclosure designed to minimise resonances
• Suitable for placement close to rear walls
• Manufactured in Switzerland at Piega’s Lake Zurich facility

Aluminium Enclosure Design for Acoustic Stability

The Premium 801 employs an aluminium enclosure formed from a high-pressure extruded profile. This construction method provides a rigid, low-resonance structure that supports fast transient response and controlled energy dissipation. The seamless front baffle contributes to a clean visual appearance while also serving acoustic purposes by reducing diffraction effects.

Three different foot options are available, allowing the loudspeaker to be adapted to a wide range of living environments. Users can choose between a standard round base, furniture gliders, or an optional aluminium base plate with adjustable spikes for precise levelling and mechanical decoupling.

Horn-Loaded Ribbon Tweeter Technology

The most notable technical innovation in the Premium 801 is the combination of a magnetostatic SSD ribbon tweeter with a horn attachment. According to the manufacturer, the extremely low mass of the ribbon enables very fast impulse response, while the horn increases efficiency, improves horizontal dispersion control, and enhances presence energy.

By moving the acoustic centre of the tweeter closer to the midrange driver, the horn-loaded design is also intended to improve time alignment and phase coherence. This approach aims to deliver a more stable spatial presentation and a smoother transition between frequency bands.

FSD Midrange and Bass Driver Platform

The midrange driver used in the Premium 801 has been developed specifically for this model. Its symmetrical voice-coil arrangement is designed to ensure linear membrane movement, which can result in reduced distortion and a more natural reproduction of vocals and acoustic instruments.

Bass reproduction is handled by four 140 mm FSD woofers. The increased total diaphragm area compared to previous Premium models is intended to support higher sound pressure levels while maintaining control and depth in the low-frequency range.

Crossover Design and Amplifier Compatibility

The crossover network of the Premium 801 has been engineered with amplifier compatibility in mind. A stable impedance curve and a nominal 4-ohm load make the loudspeaker suitable for a wide range of amplifier designs, including both Class AB and modern Class D solutions.

The connection panel features robust screw terminals and supports bi-wiring. Piega’s Multi Connectors, previously introduced in the Coax Series, are used to ensure reliable and low-loss signal transmission.

Sound Character and Intended Performance

According to Piega, the horn-loaded ribbon tweeter delivers an open and dynamic high-frequency response while preserving fine detail. The integration with the midrange driver is designed to sound seamless, allowing voices to appear clearly defined and spatially precise.

The four bass drivers contribute a solid low-frequency foundation that aims to remain controlled rather than exaggerated. Overall, the Premium 801 is positioned as a loudspeaker combining analytical precision with long-term listening comfort.

Price and Availability

The Piega Premium 801 is available in three finishes. The aluminium silver anodised version is priced at € 4.950,- per unit, while aluminium black anodised and aluminium white lacquered versions are priced at € 5.250,- per unit. The optional aluminium base plate with adjustable spikes is available in silver or black anodised finishes and costs € 525,- per unit. All versions and accessories are available through authorised retailers.

Conclusion

With the Premium 801, Piega introduces a new technological concept within its Premium Series. The use of a horn-loaded ribbon tweeter represents a notable departure from previous designs and is intended to improve efficiency, coherence, and spatial precision. Combined with a newly developed FSD driver platform and a rigid aluminium enclosure, the Premium 801 positions itself as a technically ambitious evolution rather than a simple model extension.
