Revival Audio Sprint 4 Floorstanding Speakers

Revival Audio Sprint 4 passive floorstanding speakers are designed for home music systems using an external amplifier supporting 4-ohm loads. They combine dedicated bass reproduction with separate midrange/bass and treble drivers in a 2.5-way design.

Developed and designed in France, these speakers bring acoustic technologies from the ATALANTE series into the SPRINT range. Their development draws on almost four decades of experience.

The design also reflects collaboration with Paris-based A+A Cooren Design, a recipient of the Le French Design 100 award. Acoustic engineering, a specially finished cabinet, and a removable front panel form part of the Sprint 4 design.

Benefits of the Sprint 4 Design

• Targeted resonance absorption – Patented ARID+ technology works with a dedicated rear acoustic chamber, absorbing more than 95% of unwanted chamber resonance.
• Responsive bass diaphragms – BSC construction combines stiffness with low weight, supporting fast, even driver response and controlled bass dynamics.
• Controlled treble directionality – The asymmetric ELYTRON front panel acts as a waveguide, giving this visible component a specific acoustic role.
• Reduced cabinet diffraction – The front panel’s shape reduces the cabinet’s influence on midrange and bass reproduction through its diffraction-reducing geometry.
• Coordinated driver operation – The 2.5-way crossover aligns the two BSC drivers, improving phase accuracy while extending low-frequency reproduction.
• Removable magnetic front panel – Magnetic attachment makes the panel easy to fit and remove, with fabric-covered protective grilles attached from behind.
• Improved treble dispersion – The tweeter’s asymmetric suspension supports more linear, resonance-free dome movement and allows sound waves to spread more freely sideways.

Who Are These Speakers For?

The Sprint 4 suits listeners building a music system around separate amplification and their chosen source components. Its passive architecture places speaker amplification in the connected amplifier, making amplifier matching part of the system setup.

For record listeners, the Sprint 4 reproduces vinyl playback through source equipment connected to that amplifier. It also accommodates contemporary playlists through connected sources, allowing the same speakers to serve different music collections.

These floorstanding speakers are intended for living rooms and dedicated home entertainment spaces. Their application centres on domestic music listening, with the external amplifier connecting the speakers to the rest of the system.

Technical Specifications

Why Choose Revival Audio Sprint 4?

The Sprint 4’s BSC diaphragms use basalt, selected felt, and a special polymer adhesive as a coordinated three-layer structure. The felt sits behind the basalt diaphragm, while the adhesive lies between these materials. Together, these layers provide diaphragm damping alongside the basalt construction’s balance of rigidity and lightness.

The RASC tweeter combines a soft dome with a coating developed using a proprietary formula. Meanwhile, its enlarged ferrite magnet system generates strong magnetic force. Its BCD rear cover has carefully modelled asymmetric edges that absorb resonance and help achieve the low tweeter resonant frequency.

The Sprint 4 brings almost four decades of development experience to a cabinet with a deliberately shaped acoustic front panel. Its ELYTRON geometry controls high-frequency directionality, linking the speaker’s exterior form to its acoustic behaviour.

FAQ

Which external amplifier is suitable for the Revival Audio Sprint 4?

• The Sprint 4 requires an amplifier capable of handling its impedance load. Its minimum impedance reaches 3.8 ohms at 200 Hz, an important figure when checking amplifier compatibility.

Can the Sprint 4 work with vinyl and playlist-based home music systems?

• Yes. The Sprint 4 reproduces records and contemporary playlists through suitable source equipment connected to the external amplifier. Those sources feed the amplifier, which powers the speakers.

How do the two BSC drivers divide the sound?

• One BSC driver handles midrange and bass, while the second concentrates on bass reproduction. The crossover coordinates their operation for more accurate phase behaviour and extended low-frequency output.

Does the 91 dB figure describe the complete speaker?

• No. The 91 dB figure describes the individual tweeter’s efficiency. The complete Sprint 4 has 89 dB sensitivity, measured at 2.83 V from a distance of one metre.

How much rear-chamber resonance does the tweeter treatment absorb?

• The tweeter’s patented resonance-control system and rear acoustic chamber absorb more than 95% of unwanted chamber resonance. This treatment addresses resonance within the tweeter chamber.

What does the asymmetric tweeter suspension contribute?

• The asymmetric suspension helps the dome move more linearly without resonance. It also lets sound travel more freely sideways, improving high-frequency dispersion.

The Revival Audio Sprint 4 combines dedicated driver technologies with a 45 Hz-22 kHz frequency response for home music listening.
